Without ROOM_PASSWORD the guest password defaults to empty, and a client
sending a blank password is granted read+write access (can post). Every
other board's room_server env sets ROOM_PASSWORD; the ThinkNode M6 and M1
were the only two shipping an open room. Default them to "hello" to match
the rest of the tree; operators can still change it at runtime with
'set guest.password'.
next_check and next_gps_update stored a future millis() value in a signed
long and compared with a naive '>'. After the ~24.8-day millis() sign flip
the deadline sits above the wrapped millis(), so the block never runs again
and GPS->RTC time-sync (and the location cache refresh) stall permanently
until reboot. Switch to unsigned deadlines with the wrap-safe signed-
difference compare '(long)(millis() - deadline) > 0', matching the idiom in
Dispatcher::millisHasNowPassed.
Also: reorder the MicroNMEALocationProvider ctor init-list to declaration
order (silences -Wreorder) and drop the always-true 'if (_claims > 0)' guard
in claim() (claim() always runs after _claims++, so it is >= 1).
The M6 is the only board whose simple_repeater env ships with MESH_DEBUG=1
and GPS_NMEA_DEBUG=1 enabled. MESH_DEBUG=1 adds a 5-second boot delay
(examples/simple_repeater/main.cpp) plus verbose per-packet serial prints on
the hot RX/TX path; GPS_NMEA_DEBUG=1 echoes every GPS UART character to the
serial console (MicroNMEALocationProvider.h). Every sibling repeater env
(M1, M3, t1000-e, RAK, Heltec) ships these off, and the M6 room_server env
in this same file already has them commented. Comment them out to match.
External watchdog support was added (but never merged) for MeshTower V1. The update's V2's #defines to follow the conventions set there and piggy back off the support already written for V1.
The host-side build/verify/inspect/serve CLI now lives as a standalone Rust
project at https://github.com/vk496/motatool. Remove the in-tree C++ copy
(tools/motatool/) and repoint the docs (ota_protocol.md, ota_user_guide.md,
tools/mota/README.md) at the standalone repo.
No cross-dependency either direction: MeshCore's firmware build never invoked
motatool (only tools/mota/ Python glue runs in the build), and motatool depends
only on the shared .mota wire spec in docs/ota_protocol.md. tools/mota/
(pio_endf.py EndF hook, motalib.py reference lib, gen_targets.py) is unchanged.
The T096 is an nRF52840 with the same S140 v6 SoftDevice and flash geometry as
the RAK4631, so it can reuse the shared rak4631_hw OTA recipe (ENABLE_OTA +
OtaFlashLayout_nrf52.h — APP_BASE 0x26000, staging ceiling 0xD4000, all
static_asserts satisfied by the stock nrf52840_s140_v6[_extrafs] ldscripts).
With the OTAFIX bootloader (oltaco PR #42 adds the T096 board) a node applies
in place; without it the node still discovers/relays/serves OTA and merely
fetch-refuses apply — so a T096 is a useful OTA relay/seeder regardless.
MOTA_HW_ID='"Heltec_t096"' tags the EndF trailer so a .mota built for other
hardware is refused. Propagates to every T096 role via ${Heltec_t096.*}.
Verified: repeater + companion_radio_usb build clean, 14 OTA objects each,
EndF stamped (hw='Heltec_t096', v1.17.0).
Second-channel pipeline for mqtt-observer-plus, mirroring
build-observer-firmwares.yml with full channel isolation:
- rolling tag observer-mqtt-plus-latest (never shared: per-tag asset pruning
would cross-delete on a shared tag)
- FIRMWARE_VERSION v1.16.0-plus, separate build counter
- OTA_MANIFEST_BASE overridden to /v-plus at build time so device pull-OTA
can never hop a plus node back onto the stable channel (env build flags
append after ini flags, so the override wins — verified in the binary)
Not enabled: workflow_dispatch only (push trigger staged in comments), and
the flasher-repo sync is gated behind SYNC_FLASHER=false with a fail-closed
guard so a premature enable cannot clobber the stable config.json. The
header documents the flasher-side prerequisites (channel-aware
update-firmware.py, SPA channel picker, v-plus manifests, plus changelog).
Manual dispatch already works for publishing hand-flashable test builds to
the release page.
The observer firmware workflow depends on three build.sh behaviors that the
keymindCascade merge dropped:
- embedded-version tagging: observer builds report
v<base>[.<FIRMWARE_BUILD_NUMBER>]-observer-<hash> via ver/MQTT/SNMP while
asset filenames stay <env>-v<base>-<hash>
- -DOTA_VARIANT injection (selects the slim per-variant manifest for pull-OTA)
- per-env .partsig emission (OTA partition-compatibility gate)
Re-applied inside the keymind build_firmware/collect_esp32_artifacts
structure. Verified by building Heltec_v3_repeater_observer_mqtt with the CI
flags set and checking the embedded version/URL strings in firmware.bin.
Integrates Mike Carper's transmission-reliability work (direct retries with
SNR-adaptive backoff and CR, flood retry controls, alt-path replies, flood
channel gates) plus its upstream/dev base (as of 2026-07-06) on top of the
observer stack. The flex branch is untouched; this branch is the experimental
integration line.
Conflict-resolution decisions, for future re-syncs (git rerere is enabled and
has recorded these):
- NodePrefs adopts keymind/upstream member order + retry/flood tail. Member
order is in-memory only: /com_prefs stays field-by-field with the same
canonical file order both sides already share through offset 294; keymind
appends the retry tail at 295+ (new canonical size 676). Flex fleet files
load unchanged; retry fields default via direct_retry_prefs_magic.
- loadPrefsInt keeps the fork's legacy MQTT-gap recovery but moves its
detection boundary from 'extra > 5' to 'extra > LEGACY_MQTT_GAP_3SLOT (864)'
so keymind-size tails take the normal read path. COM_PREFS_TAIL_BYTES
retired.
- Dispatcher/RadioLibWrappers: fork watchdog additions + keymind TX overrides
and CAD busy counter are unioned; RxReservePacketManager::queueOutbound
follows upstream's new bool return (false when shedding).
- CommonCLI: fork observer dispatch + versioned /mqtt_prefs machinery kept;
keymind CLI (retry/flood/radioat) taken; duplicate CAD/FEM handlers and
sanitise lines deduped (kept keymind placements to minimize future diff).
- MyMesh (repeater/room): fork alerter/OTA/observer wiring kept; keymind
scheduled-radio system replaces the old pending_* temp-radio members;
applySavedRadioParams() replaces raw setParams at startup.
- ESP32Board: fork manifest-OTA + keymind powerOff/deepSleep and stopOTAUpdate
unioned; startOTAUpdate keeps fork's STA-aware IP with keymind's idempotency
guard.
- build.sh taken wholesale from keymind (fleet builds use GH Actions).
Verified: Heltec_v3_repeater_observer_mqtt, Heltec_v3_repeater,
heltec_v4_repeater_observer_mqtt, Heltec_v3_room_server_observer_mqtt build;
host migration harness (13 MQTT + non-MQTT scenarios) passes with updated
expectations (676-byte /com_prefs; odd-size files normalize on save, not
load); native unit tests 13/13.
Merges three stacked PRs in one push so the rolling release only builds
the final state:
#20 — Complete observer settings migration and upstream-seam cleanup
- Implement the missing one-time /com_prefs -> /mqtt_prefs observer
settings migration (silent data loss on upgrade before this).
- Harden /mqtt_prefs into a versioned format (magic + version +
payload_len header); legacy headerless layouts detected by size and
migrated once. Drop vestigial _legacy_* fields.
- Deployed flex layout pinned by static_assert (Legacy6SlotMQTTPrefs ==
2904 bytes); verified with the host migration harness and on-device
(Heltec V4: presets, WiFi, and origin survive upgrade and reboot).
#21 — Restore upstream duty-cycle enforcement and CAD
- Restore Dispatcher/StaticPoolPacketManager verbatim from upstream/dev
(token-bucket duty cycle, CAD interface); re-apply the MQTT radio
watchdog as pure additions behind WITH_MQTT_BRIDGE.
- Restore cad_enabled and radio_fem_rxgain persistence at upstream's
/com_prefs offsets (byte-parity with upstream, tail 3 -> 5 bytes).
- Add RxReservePacketManager for observer builds: priority-aware shed +
30s stale expiry so heavy throttling can't park the packet pool and
make the node un-administrable.
- Device-confirmed on Heltec V4.2: throttling holds at set dutycycle 1
on a busy mesh, CAD persists across boots, capture continues at full
rate under throttle.
#22 — Drive LoRa FEM RX gain from radio_fem_rxgain
- MainBoard gains setLoRaFemLnaEnabled/canControlLoRaFemLna/
isLoRaFemLnaEnabled; wired for heltec_v4, heltec_t096, and
tracker_v2. radio.fem.rxgain CLI gated on board capability.
- Persisted pref applied at app startup; defaults ON (upstream parity),
so LNA-capable boards gain RX boost on upgrade.
- Guard path device-confirmed on V4.2 (GC1109, PA-only: reports
unsupported). LNA toggle on V4.3/KCT8103L pending hardware.
Multi-hour soak on the full stack: no memory issues or regressions.
Duty-cycle throttling, CAD-under-load, capture decoupling, remote admin under
throttle, and radio-watchdog fire/recover all device-confirmed on a Heltec
V4.2 (busy mesh + off-frequency bench). Notes the watchdog observability
gotchas found during testing: silent on release builds (check stats-radio-diag
err_flags bit 8) and armed only after first radio activity.
Device testing at 'set dutycycle 1' on a busy mesh showed the node becoming
un-administrable within ~2 minutes: the shed policy dropped its own CLI
responses along with repeats, and parked retransmissions (which never expire)
absorbed every budget refill.
RxReservePacketManager now sheds by priority below the RX reserve — only
pri > 1 outbound (multi-hop flood repeats, adverts, trace) is refused, so the
node's own responses/ACKs (pri 0) and login/PATH replies (pri 1) still queue;
below an emergency floor (reserve/2) everything is shed to protect capture.
Queued packets untransmitted 30 s past their scheduled time are expired at
dequeue via a pointer-keyed age table (the pool is a fixed set of packets, so
pool_size slots cover every key). Under normal load the queue drains in
milliseconds and neither policy triggers.
Load-testing the restored token bucket at 'set dutycycle 1' showed MQTT
capture dropping to exactly the TX rate. Queued retransmissions hold static-
pool packets with no expiry, so throttling parks the whole pool in the send
queue; Dispatcher::checkRecv() then discards received packets before logRx()
ever feeds the bridge — each completed TX frees exactly one packet for
exactly one more RX.
Observer builds now use RxReservePacketManager (fork-owned header): once the
free pool drops below a quarter of the pool, outbound packets are refused and
freed, so RX allocation and MQTT capture continue at full rate while the node
sheds repeat load it has no TX budget for anyway. Non-observer builds keep
upstream pool behavior via the same factory; StaticPoolPacketManager stays
byte-identical to upstream.
companion_radio has its own NodePrefs without radio_fem_rxgain (matching
upstream, which doesn't wire companion either), so the startup call added in
e905451d broke every companion build:
MyMesh.cpp:973: error: 'struct NodePrefs' has no member named 'radio_fem_rxgain'
It went unnoticed behind the pre-existing companion build failures.
Also port upstream's FEM LNA overrides for heltec_t096 and heltec_tracker_v2
verbatim (board overrides + isLNAEnabled/const getters), so all three boards
upstream wires now match instead of reporting unsupported. Both variant files
compile; those targets still fail overall on the pre-existing non-observer
MQTT-source build-config issue (unchanged with this work stashed).
performChannelScan was restored as protected non-virtual but upstream declares
it public virtual — match upstream verbatim so the hunk disappears from the
merge surface. Also replace the bare 'extra > 5' tail threshold with
COM_PREFS_TAIL_BYTES, tied by comment to the trailing writes in savePrefs(),
so the next upstream field append updates one named constant.
The unknown-version path kept defaults at boot but any later savePrefs()
(every CLI set command) rewrote /mqtt_prefs as v1 with defaults, destroying
the newer config after a firmware downgrade. Latch _mqtt_prefs_hold when an
unsupported version is seen and refuse to write while it is set — checked
before the NRF52/STM32 open path, which deletes the file first.
Also pin the frozen legacy /mqtt_prefs layouts (472/1464/2904 bytes + 8-byte
header) with static_asserts so every target build re-verifies the deployed
fleet's file offsets, and null-check _obs in AlertReporter::onLoop.
Completes the FEM RX-gain restoration begun in the CAD/prefs change, which
persisted radio_fem_rxgain but didn't yet drive the hardware. Also dropped
by the 22eb9b87 revert; restored to match upstream.
- MainBoard: setLoRaFemLnaEnabled()/canControlLoRaFemLna()/isLoRaFemLnaEnabled()
virtuals (default: can't control — non-FEM boards report unsupported)
- heltec_v4: board overrides driving loRaFEMControl; LoRaFEMControl gains the
isLNAEnabled() getter (it already tracked lna_enabled and drove the FEM)
- CLI: `set radio.fem.rxgain on/off` / `get radio.fem.rxgain` (guarded by
canControlLoRaFemLna, so it reports "unsupported" on non-FEM boards)
- app startup applies the persisted pref: board.setLoRaFemLnaEnabled(
_prefs.radio_fem_rxgain), beside setRxBoostedGainMode
Default is ON (upstream), so on FEM boards the LNA is enabled after upgrade —
a real reception behavior change to confirm on hardware. The other FEM
variants (heltec_t096/tower_v2/tracker_v2) need the same small board-override
addition; until then `radio.fem.rxgain` reports unsupported there (no
regression — status quo).
Builds: heltec_v4 repeater-observer + room-observer (FEM board), Heltec_v3
repeater (non-FEM, base virtuals no-op). NEEDS on-device validation on a
Heltec V4.
Continues restoring features dropped by the 22eb9b87 revert. Both were
upstream-tested code, not intentional fork removals.
CAD (hardware Channel Activity Detection / listen-before-talk before TX),
fully restored and functional:
- NodePrefs.cad_enabled + `set cad on/off` / `get cad` CLI (default off)
- RadioLibWrapper: _cad_enabled + setCADEnabled() + the scanChannel()/CAD
branch in isChannelActive() (Phase 1 already restored the Dispatcher hook)
- getCADEnabled() overrides in the repeater/room/sensor apps (return the
pref) and companion (always on, matching upstream)
radio_fem_rxgain: the NodePrefs field + /com_prefs persistence are restored
here at upstream's exact offsets (293 fem, 294 cad), which makes /com_prefs
byte-identical to upstream through the tail. The field is persisted and
defaults on (upstream default), but the per-board LNA *driving* + the
`radio.fem.rxgain` CLI are deferred to the FEM-hardware change (they depend
on board methods and want per-board bench testing).
The new-format /com_prefs tail grows from 3 to 5 bytes; the old-format
detection threshold and the host migration harness are updated accordingly
(all scenarios pass, incl. the non-MQTT-build variant).
Builds: Heltec_v3 repeater, repeater-observer, room-observer. (sensor /
plain-room / companion fail only on the pre-existing Timezone.h include
issue, unrelated to these changes.)
Commit 22eb9b87 ("Revert 'Merge remote-tracking branch origin/dev...'")
reverted an entire upstream merge to escape a bad merge state, dropping
860 lines across 66 files. Among the collateral never reconciled on a
later re-merge was eb4fa032's token-bucket duty-cycle enforcement — the
mechanism that keeps nodes under a configured airtime budget (and EU
868 MHz nodes under the legally-mandated duty cycle). The fork had fallen
back to fixed per-packet spacing (getAirtimeBudgetFactor reverted to 2.0),
losing the windowed enforcement.
This was never an intentional design choice, so restoring it re-aligns the
fork with upstream and REDUCES the merge-conflict surface: Dispatcher.{h,cpp}
now diverge from upstream by watchdog additions only (77 insertions, 0
deletions) instead of rewriting checkSend()/loop().
Restored from upstream: updateTxBudget/tx_budget_ms/duty_cycle_window_ms/
getRemainingTxBudget/getDutyCycleWindowMs and the windowed budget logic in
Dispatcher; getOutboundTotal() and the 0xFFFFFFFF count-all sentinel in
StaticPoolPacketManager; the getOutboundTotal() call in StatsFormatHelper.
Re-applied the fork's MQTT radio-watchdog on top as pure additions
(#ifdef WITH_MQTT_BRIDGE), keeping formatRadioDiag.
Stored airtime_factor settings keep their meaning: fork's t*factor spacing
and upstream's 1/(1+factor) windowed budget yield the same steady-state
duty cycle; upstream additionally allows short bursts within the window.
Phase 2 (CAD / radio_fem_rxgain, which touch NodePrefs persistence and
per-board FEM wiring) is documented in RESTORE_UPSTREAM_NOTES.md, not done
here. Builds: Heltec_v3 observer + plain repeater. NEEDS ON-DEVICE
duty-cycle validation before merge.

The /mqtt_prefs format was detected purely by struct size, which is fragile
(size collisions across eras) and forced the vestigial `_legacy_*` fields to
be retained forever to preserve byte offsets. With ~several thousand observer
devices deployed from the rolling `observer-mqtt-latest` flasher, this is the
last safe moment to fix it before the observer-settings split ships.
/mqtt_prefs now leads with an 8-byte MQTTPrefsHeader (magic {0xF5,'M','Q','P'},
version, payload_len) followed by the raw payload. The magic's non-ASCII lead
byte cannot collide with a legacy file (whose payload starts with the
mqtt_origin string), so versioned and headerless files are cleanly separable.
An unrecognized (newer) version leaves the file untouched and falls back to
defaults rather than misreading it.
MQTTPrefs is compacted: the six `_legacy_*` fields are removed. Every deployed
headerless layout — pre-slot (OldMQTTPrefs), 3-slot (ThreeSlotMQTTPrefs), and
the shipped 6-slot flex layout (new Legacy6SlotMQTTPrefs) — is field-copied
into the compact struct and re-saved with the header once, on first boot.
Future fields append to the payload and stay backward compatible.
Verified with a host harness that generates a byte-exact deployed flex
/mqtt_prefs (the flex MQTTPrefs is confirmed identical to Legacy6SlotMQTTPrefs,
2904 bytes) and round-trips it through the new load path, plus pre-slot/3-slot
migration, unknown-version safety, magic/origin collision-safety, and the
combined /com_prefs observer-tail recovery. Observer + room-server + no-MQTT
ESP32 targets build.

The Files section (source layout, upstream integration seams, and
on-device settings migration) is developer-facing detail that sat near
the top of the otherwise user-facing MQTT_IMPLEMENTATION.md. Move it to
a new MQTT_INTERNALS.md and link it from the bottom of the main doc.

The NodePrefs->MQTTPrefs split (2eb41bae) left the promised one-time
migration of the old /com_prefs trailing block unimplemented, so users
upgrading an observer node silently lost SNMP, radio-watchdog, and
fault-alert configuration (alerts reset to off; PSK/hashtag/region wiped).
loadPrefsInt now detects an old-format /com_prefs by its size, skips the
legacy zero-filled MQTT gap (6-slot or 3-slot era), and recovers the
trailing observer block into a LegacyObserverTail (reusing the old
firmware's byte291/292 heuristic and per-field availability guards).
loadMQTTPrefs applies those values when the loaded /mqtt_prefs predates
the appended observer fields, and both files are rewritten once in the
current layout. rx_boosted_gain/flood_max_* are also recovered from the
correct offsets (previously read from inside the old gap and reset).
Verified with a host-side harness that round-trips the real old-firmware
savePrefs (from 2eb41bae^) through the new load path across upgrade,
fresh-install, upstream-format, 3-slot-era, truncated, and legacy-variant
cases, plus a non-MQTT-build variant. Updates the stale migration comments
and documents the CommonCLI_Observer seam in MQTT_IMPLEMENTATION.md.

Updated MQTT configuration to succeed when port is defined in mqttN.server but not explicitly set in mqttN.port. Updated documentation to specify that when a full
URL with a scheme is provided, the port setting is optional. Added an
example for local development using a plain WebSocket URL, enhancing
clarity for users configuring custom MQTT brokers.
Spell out how the warm-start seed is actually applied (a user asked): the seed is the --seed <file> given to `motatool serve`, NOT a file dropped into the --dir destination (which starts empty). motatool stamps that one seed into the fresh .part on every `… folder validate` begin, so it's always the named file — no guessing. `validate` is the switch (a plain folder pull fetches from 0); a re-pull re-begins fresh (never resumes a stale partial); a mismatched/absent seed just falls back to fetching those blocks over the radio (correct result, only slower).
The EndF post-build stamper read the version via _cppdef('FIRMWARE_VERSION'), which only sees -D build flags — but MeshCore authors FIRMWARE_VERSION as a header #define in each example, so the stamper found nothing and defaulted fw_version to 0. Every .mota / OTA advert then reported v0.0.0 while `ver` (which reads the header at runtime) showed the real version.
Read the header value as a fallback WITHOUT moving where MeshCore authors it: honor a -D override first (the header's #ifndef guard invites it, for release builds), else read the #define from the example this env builds (via build_src_filter), falling back to the repo-wide value when unambiguous. Purely additive to our own EndF tooling — no MeshCore source changed.
HW-verified: RAK4631 now reports `fw v1.17.0` in ota stats/ls (was v0.0.0), matching `ver`.
Add an admin-only `ota stats` reply: one dense line with the running firmware's merkle content-id (mid) AND its EndF body_hash (only body_hash was surfaced before), version, served-set count + digest, live fetch state/progress, and policy — snprintf-bounded to the 160-byte reply. The remote CLI path is already admin-gated, so it's admin-only over the mesh (send it from the app's repeater command screen, or the WiFi/serial OTA console). A new servedDigest() accessor exposes the beacon set-digest.
HW-verified on RAK4631: reports the fw identity + live fetch state (incl. during a warm-start capture).
Protocol: OTA_REQ and OTA_GET_MANIFEST now carry a want_mask bitmap, so a fetcher asks for specific fragments (all on the first request, only the still-missing holes on a retry) instead of a whole block/manifest window. The WANT_MANIFEST and FETCHING retry loops re-ask only on a no-progress tick, so a lost fragment costs one fragment to recover and a re-request can't collide with an in-flight multi-fragment burst on half-duplex radios.
Warm-start (motatool folder-capture only): new OTA_GET_LEAVES/OTA_LEAVES let `ota pull <#> folder validate` bulk-fetch the target's merkle leaves, authenticate them against the manifest root, diff a similar seed build already staged in the destination, and pull DATA over LoRa only for the blocks that differ. Leaves are bitmap-fragmented + no-progress retry-gated like the manifest, capped at OTA_DIFF_MAX_BLOCKS so the want_mask stays a fixed uint16, and the diff runs a bounded batch per loop tick so it never starves the mesh loop. motatool `serve --seed <build.mota>` injects the seed payload into the destination .part on OP_BEGIN.
Route both begin() and reopen() through a pure mota_nrf52_stage_plan() that bottom-aligns a received .mota below the filesystem region (trailer ending at FS_START, where the bootloader scans) and refuses any size that would overrun that ceiling or overlap the running image — the single place the FS/prefs-safe bounds are enforced. Add compile-time static_asserts pinning the flash-layout ordering (app < staging ceiling < bootloader; in-place workspace ends at/below the ceiling) so an inconsistent constant fails the build instead of silently corrupting user prefs. Cover the pure planner in test/test_ota/test_ota_flashplan.cpp.
The `recv_pkt_region` is set when processing a flood packet in `filterRecvFloodPacket`
but direct/non-flood packets would never pass through that function, so the pointer was
not cleared for them.
`sendFloodReply` would then later use it blindly, which meant that the response would
either inherit the region from the last flood packet, or refer to a non-initialised pointer
if no region floods had been received yet.
Document `ota pull <#> <dest>` (flash|folder, destination mandatory), the folder
pull that captures a device's exact firmware to the host as <mid>.mota (for
delta-building), the paused/resume-on-reconnect behaviour, and that a `motatool
serve` link doubles as the pull-to-folder store. (protocol §10, user guide,
motatool README)
If an `ota pull <#> folder` block-write fails mid-transfer (the motatool seeder
link dropped), the fetch enters a new PAUSED state instead of failing or falling
back to RAM/flash: progress stays on the host, the manager stops requesting, and
loop()/stall-detection leave it untouched (it waits indefinitely). On reconnect
the ESP32 seeder re-registers the folder destination and, if PAUSED, calls
resumeStaged(): OP_STAT re-attaches the host's partial, the leaves are re-read,
and only the missing blocks are re-requested (a brand-new/absent file restarts
from 0). `ota status` reports the paused state.
FolderMotaStore: an OtaStore that streams an in-transit .mota straight to the host
folder over the seeder link (OP_BEGIN/WRITE/SREAD/STAT/FIN) instead of RAM/flash —
the device holds no local staging for it. Wired as a selectable pull destination:
- OtaContext gains a folder_dest (registered by the app while a motatool `serve`
link is up) + its human id (e.g. "tcp 192.168.4.5").
- `ota pull <#> <dest>` now takes a MANDATORY destination; `ota pull <#>` with none
lists the choices (flash always; folder + its link id when connected).
- The ESP32 WiFi seeder registers/clears the folder destination on connect/close —
the same connection both serves the folder and accepts pulls into it.
Captures an exact copy of a device's firmware over the mesh to build a delta
against. Pause/resume on a mid-pull disconnect follows.
Add the device->host WRITE half of the mota-seeder link so a device can capture
a .mota it is fetching off-mesh into the host folder (the same --dir used for
serving), stored as <mid>.mota — e.g. to grab an exact copy of a device's
firmware to build a delta against firmware you don't otherwise have.
- MotaSeederProto: OP_STAT / OP_BEGIN / OP_WRITE / OP_SREAD / OP_FIN (keyed by
mid). Resume needs no host bookkeeping: BEGIN 0xFF-fills the file; on reconnect
the device SREADs the leaves and re-requests only missing blocks (same as flash
resume). Partial = <midhex>.mota.part, published to <midhex>.mota on FIN.
- motatool `serve --dir <folder>` now also handles the storage ops on the same
folder/connection (SeederCore gains the store dir; serve_loop frames the
variable-length WRITE). Host round-trip test added.
Firmware side (FolderMotaStore + `ota pull <#> <dest>` + pause/resume) follows.
hasSeen() was simultaneously a predicate and a mutator — it inserted the
packet hash on every miss, making five call sites that only wanted to mark
a packet as sent call it with the return value discarded.
Split into:
- wasSeen() — pure predicate, no side effects
- markSeen() — explicit insert
All query sites now call markSeen() immediately after wasSeen() returns
false, preserving identical runtime behaviour. The five mark-only send
sites (sendFlood, sendDirect, sendZeroHop x2) now call markSeen directly.
Also fixes three bridge sites (BridgeBase, ESPNowBridge, RS232Bridge)
that had the same query+implicit-insert pattern.
Tests: add test/test_mesh_tables/ covering wasSeen purity, markSeen,
dup stats, and clear. Update SHA256 mock to produce deterministic output
(previously finalize() was a no-op). Add Packet.cpp to native build filter.
Bound OTA-over-LoRa duty cycle across repeaters with one runtime-tunable,
persisted limit (OtaManager::max_hops, `ota config hops <0..8>`, default 3):
- Accept-gate: a node ignores OTA that arrived from more than max_hops hops
away (neither processes nor relays it). 0 = direct only.
- Forward-cap: relay a flood only while still under max_hops, appending this
node's path-hash (hop count increments like the mesh flood routing).
- RAM guard: relay an OTA flood only while more than OTA_FWD_MIN_FREE packet-
pool slots stay free, so heavy OTA (best-effort, lowest-priority) can never
monopolise the shared pool and starve real traffic — a dropped relay is
re-requested by the source.
Persisted in NodePrefs (CommonCLI) and shown in `ota config`. Docs updated.
The discovery beacon previously re-announced at a random 3-10 min interval.
Replace that with a fixed, user-configurable cadence:
- OtaManager::advert_mins() — re-advertise every N minutes after the boot
burst; 0 disables periodic re-advertise (boot burst only). Default 24h.
- Persisted in NodePrefs (CommonCLI) and runtime-tunable: `ota config advert
<minutes>` (0..10080; 0 = off), and shown in `ota config`.
- When periodic advert is disabled, the scheduler still re-checks the config
on a slow timer, so a later `ota config advert <mins>` takes effect live.
Also advertise immediately whenever the served set changes — when a motatool
folder is attached to / detached from the ESP32 WiFi seeder — so peers learn
about newly-available firmware without waiting for the next interval (the
`ota folder` serial path already announced on attach).
Docs: protocol beacon-cadence note + user-guide `ota config advert`.
- Added build flag "SX126X_USE_REGULATOR_LDO" (set to 1 to enable) to use LDO for the SX1262 radio instead of DC-DC when the DCDC pin isn't wired up (e.g. t-echo lite)
- Added additional debug mode diagnostic messages during SX1262 init to better highlight faults
Switch these existing variants from `nrf52_base` to `rak4631_hw` (which adds
ENABLE_OTA + the in-place flash store + the EndF post-build hook), so they get
OTA-over-LoRa. Scope is limited to variants already covered by the
Adafruit_nRF52_Bootloader_OTAFIX in-place apply — no new variants are added.
OtaTargets.h is regenerated to include their target ids.
Discovery was hard to use — a node only advertised at boot, so a peer that
ran `ota ls` minutes later saw "no neighbours".
- First self-advert ~8s after boot, then a short burst (~1 min), then
re-announce at a random 3-10 min interval so a long-running node stays
discoverable without all nodes beaconing in lockstep. The beacon is tiny,
lowest-priority and duty-gated, so a few-minute cadence is cheap.
- `ota ls` now shows the raw target id (`hw XXXXXXXX`) when the env name is
not in this build's OtaTargets.h table, instead of a blank "[other hw]".
Extends the USB-serial folder relay to WiFi so an ESP32 companion can both
serve .mota and be operated headlessly:
- motatool `serve --tcp <host[:port]>`: a TcpTransport sibling of the serial
transport (default port 5001). SeederCore/Folder are reused unchanged — the
COUNT/DESCRIBE/READ protocol is transport-agnostic.
- ESP32 companion: a dedicated OTA seeder port (5001) for `serve --tcp`, plus
an OTA text console on 5002 (`nc <ip> 5002` -> `ota status|ls|announce|...`,
the same handle_ota_command CLI serial nodes have). Both run alongside the
phone-app port (5000); all three coexist.
- WiFi.setSleep(false): ESP32 STA mode's modem power-save periodically sleeps
the modem/CPU and stalls the SX1262 SPI+DIO servicing, leaving LoRa deaf
while WiFi is associated. Disabling it restores the radio (HW-validated:
a V3 WiFi companion is then discovered over LoRa and discovers its peers).
- docs: serving .mota over WiFi (protocol §10.2 + user guide).
Refactored the handling of observer-related settings by moving them from
NodePrefs to a new MQTTPrefs structure. This change centralizes MQTT,
WiFi, timezone, SNMP, and alert configurations, improving code organization
and maintainability. The new structure allows for better separation of
concerns and prepares the codebase for future enhancements.
Refactored the CommonCLI class to separate observer-related command
handling into CommonCLI_Observer.cpp. This change improves code
organization and maintainability by isolating MQTT, WiFi, and other
observer-specific commands from the main CLI logic.
Improved error handling in the MQTT client to log specific reasons
for connection refusals, including detailed return codes. This change
ensures that users are informed of authentication issues and server
availability problems, enhancing the debugging experience.
Remove unused MQTTMessageBuilder members (getPacketTypeString,
formatTimestamp/Time/Date stubs, JSON_BUFFER_SIZE constant) for a
small flash saving with no behavior change.
Replace the per-byte snprintf("%02X") in bytesToHex with a nibble
lookup table, avoiding a format-string parse up to ~512x per publish
on the MQTT task. Output is byte-for-byte identical uppercase hex.
Implemented new commands for configuring and diagnosing NTP server
settings in the MQTT bridge. Users can now set a custom NTP server
and probe connectivity to configured servers. This enhancement
improves time synchronization reliability for JWT authentication
and provides better diagnostics for NTP connectivity issues.
Updated the build-observer-firmwares workflow to exclude .partsig files
when uploading release assets. This change prevents issues with the
slim-manifest generator and ensures that only relevant firmware files
are published, improving the integrity of the release process.
Implemented functionality to generate and compare partition-table
signatures during OTA updates. This enhancement ensures that the
target build's partition layout matches the device's actual layout,
improving the reliability of OTA updates and preventing issues
related to partition changes.
Updated the otaFromManifestImpl method to enhance the display of
available and current firmware versions. The changes ensure that
the short commit hash is included in the status messages,
providing clearer versioning information during OTA checks.
Improved the otaFromManifestImpl method to handle dry run scenarios
by allowing HTTP fetches without TLS, reducing heap usage on no-PSRAM
boards. This change ensures better compatibility and reliability during
OTA checks while maintaining security for actual updates.
Enhanced the firmware versioning system by appending a build number
suffix when available, allowing for better tracking of published builds.
This change improves the OTA update process by providing clearer
versioning information in the embedded firmware string.
Added support for deferred OTA updates in the MyMesh class, allowing
the system to schedule firmware updates to occur after a confirmation
reply is sent. This change improves the user experience by ensuring
that the update process does not block the main application loop,
allowing for smoother operation during firmware updates.
Updated the startOTAUpdate method to serve the ElegantOTA on the
station IP when connected to a WiFi network, enhancing accessibility
for OTA updates. If not connected, it defaults to the MeshCore-OTA
SoftAP. This change improves the user experience by allowing easier
access to OTA updates without needing to switch networks.
Updated the otaFromManifest method to stream-parse the firmware manifest
directly from the network, reducing peak RAM usage during OTA checks. This
change enhances compatibility with slow TLS links by implementing a per-read
timeout, ensuring a more efficient and reliable update process.
Updated the otaFromManifest method to enforce HTTP/1.0 for better
compatibility with CDNs and to handle empty manifest responses. This
ensures that the JSON parser receives a complete body, preventing
errors during firmware update checks.
Added functionality to support pull-based OTA updates by fetching firmware
from a manifest. The new `otaFromManifest` method allows the system to
check for available updates and flash the firmware if necessary. This
enhancement improves the update process for observer builds using the
MQTT bridge, ensuring a more seamless firmware management experience.
Updated the build-observer-firmwares.yml to improve the asset pruning
logic during the release process. The workflow now retains the most
recent build hashes to prevent 404 errors for assets that may still
be requested during build cycles. This change ensures a smoother
release experience by maintaining necessary assets while cleaning
up older ones.
Updated the MQTTMessageBuilder to include microsecond precision in the
timestamp formatting. The formatIsoTimestampForMqtt function now accepts
a microsecond parameter, allowing for more accurate time representation.
Modified related functions in MQTTBridge to utilize the new timestamp
formatting, ensuring consistency across MQTT messages.
Updated the build-observer-firmwares.yml to improve the handling of rolling releases. The workflow now creates a release only if it doesn't already exist, preventing tag conflicts. Additionally, it uploads build artifacts while replacing existing assets and prunes older assets to maintain a clean release. This change enhances the reliability and efficiency of the release process.
Introduced a radio watchdog that detects when the LoRa radio is stuck in RX mode without activity. The firmware can now idle and restart the radio after a configured silence interval, helping MQTT observers recover from missed interrupts. Added CLI commands to get and set the watchdog interval, with a default of 5 minutes. Updated documentation to include usage examples and configuration notes.
- Changed the connection details for the `meshat.se` preset from MQTT over TLS to WSS with JWT authentication.
- Updated related documentation to reflect the new connection method and authentication type.
- Removed fixed username/password mention for the `meshat.se` preset in the documentation.
Before this commit, there was no way to set a different max hop count
for unscoped messages.
Now with this change, by defaul it tracks the flood.max setting, until
a user provides a flood.max.unscoped value, which tax precidence for
packets if ROUTE_TYPE_FLOOD is true.
AUTO_OFF_MILLIS is a power-save feature aimed at battery use. When the
board reports isExternalPowered() == true (USB or other DC source),
blanking the screen serves no purpose — there's nothing to conserve.
But OLEDs are vulnerable to burn-in with static content, so this
behaviour is gated behind a new build flag KEEP_DISPLAY_ON_USB. Default
is unchanged from upstream — the display blanks after AUTO_OFF_MILLIS
on USB or battery. Variants that ship with an LCD instead of an OLED
(e.g. heltec_t096) can opt in by adding -D KEEP_DISPLAY_ON_USB to
their env, gaining always-on-while-powered without exposing OLED users
to burn-in risk.
When the flag is enabled, the implementation refreshes _auto_off every
loop iteration while externally powered, so the timer naturally counts
a fresh AUTO_OFF_MILLIS window from the moment power is removed —
no instantaneous-blank-on-unplug.
Applied to all three companion_radio UI flavours (ui-new, ui-tiny,
ui-orig). Boards without an isExternalPowered() override use the
base-class default in MeshCore.h (returns false), so battery-powered
behaviour is unchanged everywhere.

This is a consolidation of my changes for BME680 on RAK4631 nodes.
I will close my other PRs related to this and link back to this one.
*Background on change:*
This change replaces the Adafruit BME680 driver on RAK4631 with the
Bosch BSEC library. Other boards continue to use the existing
Adafruit path via ENV_INCLUDE_BME680.
This makes the IAQ portion of the sensor functional, and more accurate.
It also contains the math and/or CayenneLPP fixes from my other PRs.
The Bosch code also appears to handle calibrating sensor aging as well,
whereas the Adafruit code is just looking at blind values that can drift
with time. Pretty cool to see this shooting out useful data!
RAK4631 platform.io is set to override to ENV_INCLUDE_BME680_BSEC while
leaving the Adafruit code for other node types. (If this becomes applicable
for other node types in future, awesome! I just don't have hardware
to test against.)
Using the BSEC library introduces IAQ sensor calibration, and saves
the calibration state periodically so it does not have to calibrate
again later.
At startup the IAQ sensor takes 30 minutes to heat and to hit a baseline,
then starts calibrating. Once calibrated, it will save those settings
and will only write settings again if calibration falls back and restores
back to state 3.
This fix also has the gas resistance math fix that was in
[pull 2146](https://github.com/meshcore-dev/MeshCore/pull/2146) so
the adafruit path also can at least show accurate values instead
of looping negative.
Also includes the fix from [pull 2149](https://github.com/meshcore-dev/MeshCore/pull/2149) so the pressure output isn't truncated to 1hPa steps.
*Fixes/Changes:*
- Add bsec_config_iaq[] with the 3.3V/3s-LP/28d calibration profile
- BSEC init applies setConfig() for voltage-correct heater targeting
- IAQ, heat-compensated temperature/humidity, pressure, and altitude
reported over CayenneLPP
- IAQ accuracy reported as analog input over CayenneLPP (0,1,2,3)
- Calibration state persisted to /bsec_state.bin on nRF52 internal
flash; written only when iaqAccuracy improves to >= 2, should
keep write frequency well within flash endurance over device lifetime
- Fix non-BSEC query_bme680: float pressure division, addGenericSensor
for gas resistance (was addAnalogInput, overflows at > 327 Ohm)
- loop() correctly gated for both GPS and BSEC-only builds
- Add fix_bsec_lib.py extra_script to resolve nRF52840 hard-float ABI
mismatch in Bosch's PlatformIO packaging, silly Bosch
One general note outside of this code change: I noticed while BME680
_functions_ in companion nodes, since companion nodes run Bluetooth,
BLE preempts the CPU, and can do so mid-I2C-transaction.
This can cause the BME680 to see an anomaly and drop calibration and
start a recalibrate. This is behavior that will exist (and has existed)
regardless of using the Adafruit or Bosch paths.
This particular companion behavior does not seem to occur in sensor
or repeater nodes since their BLE is off. Probably affects other
I2C devices as well.
*Tests:*
- RAK19003
- RAK19007
- RAK19001
- repeater, sensor, companion
- Introduced a new MQTT preset for NZ Analyzer, including its connection details and JWT authentication.
- Updated documentation to reflect the addition of the NZ Analyzer preset in the slot commands.
- Increased the MQTT preset count to accommodate the new entry.
- Introduced a new MQTT preset for INW Mesh with username/password authentication.
- Updated documentation to include the new preset and its configuration requirements.
- Enhanced credential handling in MQTTBridge to support dynamic username/password assignment for presets requiring per-slot credentials.
- Improved feedback in CLI for users to set credentials when needed.
- Updated `publishPacket` method to ensure proper handling of non-TX packets.
- Added logic in `queuePacket` to directly persist serialized TX bytes in the queue entry, improving efficiency and consistency in packet processing.
Framework for upcoming variant-specific PRs that add LED feedback during boot. The hook gives users visual cues that the device is busy and
shouldn't be interacted with until startup completes.
- Introduced `Heltec_T190_room_server_observer_mqtt` and `Heltec_WSL3_room_server_observer_mqtt` environments.
- Configured SSL certificate handling and embedded files for both environments.
- Set compile-time flags for MQTT settings, including advertisement names, passwords, and MQTT bridge options.
- Updated library dependencies to include necessary MQTT and JSON libraries.
- Introduced two new MQTT presets: `meshcore-ca-1` and `meshcore-ca-2`.
- Updated documentation to reflect compile-time configuration options for MQTT defaults, including slot presets, IATA, and timezone settings.
- Removed legacy default MQTT settings from the code, now relying on the new configuration approach.
Extract the inline cursor-walk in handleRegionCmd into file-local
helpers (skipSpaces, rtrimSpaces, takeToken, splitNameJump,
processRegionDefSegment), grouped immediately above the consumer.
Behavior is identical; addresses PR #2540 review feedback on
readability.
Tighten the region def docs: collapse five Note callouts into three
grouped paragraphs (Behavior / Existing regions / Limits), add a
case-sensitivity caveat plus an error example, note the cursor reset
between split commands, and use generic placeholder names.
Modified the alert PSK command handling to only respond when the sender timestamp is zero, ensuring that the PSK is processed exclusively from the serial command line. This change enhances security and clarity in the command processing logic.
- Introduced a new method `formatIsoTimestampForMqtt` to centralize ISO-like timestamp formatting for MQTT messages, applying timezone preferences.
- Updated `buildStatusMessage`, `buildPacketJSON`, `buildPacketJSONFromRaw`, and `buildRawJSON` methods to utilize the new timestamp formatting function, improving code clarity and reducing redundancy.
- Adjusted `publishStatusToSlot` and `publishStatus` in MQTTBridge to use the new timestamp formatting method, ensuring consistent timestamp handling across status messages.
Remove the hardcoded BLE_PIN_CODE build flag from the Heltec_E290_companion_ble
environment. The presence of BLE_PIN_CODE prevents the unit from operating as a
USB companion. Commenting it out allows dynamic PIN generation and enables USB
companion functionality.
- Added guidance for using a single active WSS broker preset in the T-LoRa V2.1–1.6 MQTT observer environments, clarifying that dual TLS sessions may fail due to memory constraints.
- Updated partition table descriptions to reflect the new recommendation for the `LilyGo_TLora_V2_1_1_6_repeater_observer_mqtt` and `LilyGo_TLora_V2_1_1_6_room_server_observer_mqtt` targets.
- Enhanced platformio.ini comments to emphasize the single broker usage and its implications for memory management.
- LilyGo T-LoRa V2.1 observer envs: set ESP32_CPU_FREQ=240 and
MQTT_TASK_STACK_SIZE=16384 only for those targets so classic ESP32
TLS + JWT connect fits the FreeRTOS task; other boards keep the
default 8192 B unless overridden.
- MQTTBridge: use large JSON stack fallbacks only for PSRAM builds when
heap-backed buffers may be null; non-PSRAM paths use the inline
member buffers only, cutting peak stack in status/packet/raw publish.
- MQTTBridge.h: update the StaticJsonDocument comment (no longer refers
to an 8 KiB MQTT task stack).
Updated the alert PSK implementation to remove base64 support, now requiring a 32-character hex format for private channel secrets. Adjusted related CLI commands, error messages, and internal handling to ensure consistency with the new format. This change enhances clarity and aligns with the mobile app's "Share Channel" output. Relevant updates made across multiple files, including documentation and preference handling.
Enhanced the CLI command for setting the alert PSK to support both base64 (24/44 chars) and hex (32/64 chars) formats. This change allows for greater flexibility in key input, accommodating the mobile app's "share" output. Updated error messages for clarity and ensured that previously derived hashtags are cleared when a new PSK is set. Relevant adjustments made in CommonCLI and MQTT implementation documentation.
Add a new command `region bulk` for defining region hierarchies in a single line. This command allows users to create multiple regions in a single message. Updated the documentation to include usage examples and detailed parameter descriptions.
Modified the sendFlood method in AlertReporter to incorporate path hash size, ensuring compatibility with the repeater's configured path.hash.mode. This change enhances the handling of alert floods by accommodating different regional mesh configurations.
Added support for `LilyGo_TBeam_1W_repeater_observer_mqtt` and `LilyGo_TBeam_1W_room_server_observer_mqtt` in the MQTT implementation documentation. Updated partition table references to `default_16MB.csv` for these observers, clarifying the requirements for flashing firmware and the implications for stored settings. Enhanced the platformio configuration for both observer types, including build flags and dependencies.
Updated the fault alert functionality to include an optional region name for scoping alert floods, allowing operators to override the default scope. Introduced a list of banned channels (e.g., Public PSK, `#test`, `#bot`) to prevent spamming community channels with alerts. The implementation ensures that alerts are only sent to private PSKs or non-banned hashtags. Relevant changes were made across multiple files, including updates to the CLI for setting and retrieving the new `alert.region` preference.
Implemented a new fault alert system that broadcasts notifications over LoRa when WiFi or MQTT connections are down for a specified duration. The alerts are configurable via CLI commands, allowing operators to set private PSKs or hashtags for alert channels. Default settings for alert thresholds and intervals are established, and the system ensures that alerts do not spam the public channel. Updated relevant files to integrate this feature into the MyMesh implementations and CLI handling.
Added ColoradoMesh as a new built-in preset in the MQTT bridge documentation. Updated relevant sections to reflect this addition, including command examples and notes on topic templates. This enhances the flexibility and options available for MQTT connections.
Implemented a new function to strip surrounding quotes from strings in TxtDataHelpers, enhancing string manipulation capabilities. Updated CommonCLI to handle MQTT origin configuration, allowing for both setting and clearing of the mqtt.origin preference. This change improves the flexibility of MQTT origin management in the CLI.
Updated the MQTT message structure to add a new field for repeat status, allowing the indication of forwarding status as "on" or "off". This change includes modifications to the MQTTMessageBuilder and related documentation to reflect the new parameter. Additionally, updated CLI command documentation to clarify flooding behavior in different firmware versions.
Updated MyMesh implementations in simple_repeater and simple_room_server to set mqtt_origin to an empty string, allowing the effective origin to follow node_name during publishing. Introduced new functions in MQTTBridge to manage effective origin retrieval and refresh from preferences, ensuring consistent behavior across MQTT operations. This change simplifies the origin management and enhances clarity in the codebase.
some older ESP32 boards were pushing the limits of the dram segment causing the linker to fail, especially for ble and wifi firmwares.
lowering OFFLINE_QUEUE_SIZE reduces dram usage
This slipped through in PR #2327 and I noticed because the TechoBoard.h
for my variant doesn't include the Wire header, so the source file
in question does not coincidentally obtain a copy.
The `::init` method in the Adafruit ST7789 library is responsible to
initialize the device. This includes performing a reset, which can be
found in the Adafruit source for `Adafruit_SPITFT`.
Before this change, MeshCore performed its own ST7789 display reset
sequence, which consisted of three steps.
* Pull reset low
* Wait 10ms
* Pull reset high
Importantly, there was no fixed delay after pulling reset high. The
ST7789 driver requires a delay (T<sub>RT</sub>) of 5ms in Sleep In Mode
and 120ms in Sleep Out Mode before it will properly receive commands.
When `Adafruit_SPITFT` resets the device after MeshCore has already
reset it, the mandatory time may not have elapsed, leading to strange
behavior. In the author's case, this issue caused the initial
`fillScreen` to fail, such that the display showed an uninitialized
framebuffer.
This removes the MeshCore delay, leaving the responsibility of reset to
`Adafruit_SPITFT`, where they have the correct delays in place with
extra safety margin. The change was briefly tested by Josiah VanderZee
and Ben Zignego on a custom hardware build using an nRF52840 Dongle and
an Adafruit 4311 TFT display. The user button seemed to behave
strangely, but the display looked correct.
Introduced new PlatformIO environments for the LilyGo T-LoRa V2.1-1.6 board, including `LilyGo_TLora_V2_1_1_6_repeater_observer_mqtt` and `LilyGo_TLora_V2_1_1_6_room_server_observer_mqtt`. These environments optimize flash usage by omitting the `sensor_base` and include specific build flags and dependencies for enhanced MQTT capabilities. Updated documentation to reflect changes in partition table handling and NVS settings during firmware updates.
USE_LR1110 was missing from the preprocessor guard in CommonCLI.cpp,
causing both get and set to fail silently on T1000-E:
- get radio.rxgain returned the full radio config string (fell through
to the memcmp("radio", 5) branch)
- set radio.rxgain returned "unknown config" (no branch matched)
Fix: add -D USE_LR1110 to variants/t1000-e/platformio.ini and include
USE_LR1110 in the #if guard on both get and set branches.
CustomLR1110Wrapper already implements setRxBoostedGainMode() and
getRxBoostedGainMode() via the RadioLibWrapper virtual interface,
so no radio-layer changes are required.
Tested on T1000-E: get/set/persist all confirmed working.
Reorder login auth so that, in priority:
1. Admin password match -> ADMIN (overrides ACL — a region_mgr or
other ACL'd client who knows the admin pw can still upgrade).
2. Sender pubkey is in the ACL -> use the stored permissions
(no password required; pubkey is itself an identity assertion).
3. Guest password match (or blank pw when guest pw is unset) -> GUEST.
4. Otherwise -> reject.
Previously the ACL was consulted only when `data[0] == 0` (blank pw),
so a non-blank password would skip the ACL entirely and fall through
to the password block. Phones that sent any non-empty password field
— even a stale one — would never see their ACL-granted role; they'd
either be rejected or assigned the role implied by the password match.
Implementation is a single-line change: gate the ACL lookup on "the
admin pw did NOT match". When admin matches, we skip the lookup so
the existing password block sets ADMIN unconditionally (the right
behavior for the upgrade case). When admin does not match, the ACL
takes over; only on an ACL miss do we fall through to guest/reject.
Introduces a fourth ACL role (value 4) that can manage the region map
without full admin privileges. The role is intended for trusted users
who curate regions on a repeater but should not have access to general
admin commands.
ClientACL:
- Widen PERM_ACL_ROLE_MASK from 2 to 3 bits so the new value fits.
- Add PERM_ACL_REGION_MGR and ClientInfo::isRegionMgr().
- Exempt region_mgr entries from least-recently-active eviction in
putClient(), same as admins.
simple_repeater:
- Phones may still gate UI on the legacy is_admin byte (reply_data[6]),
so report region_mgr as admin there. Without this, the phone CLI
falls back to guest view.
- Allow region_mgr to send TXT_MSG CLI commands. handleCommand()
gates non-whitelisted commands with "Err - not permitted". The
whitelist covers region.* (read+write) plus a small set of
read-only queries (get, ver, board, neighbors, clock, sensor
get/list).
- Pass the ClientInfo* through to handleCommand and drop the
redundant sender_timestamp parameter (derived from
sender->last_timestamp; NULL means Serial CLI).
- Use ~PERM_ACL_ROLE_MASK instead of ~0x03 when clearing role bits
on login, so the wider mask is honored.
Increased the total number of built-in MQTT presets from 12 to 13 by adding the ColoradoMesh preset. This addition enhances the MQTT bridge's capabilities for connecting to more networks.
Enhanced the MQTTBridge error handling by adding several missing error codes for Wi-Fi and TLS errors, improving the clarity of error reporting during connection issues. This update includes new cases for group cipher mismatch, invalid PMKID, and TLS handshake failures, among others.
Added the EastIdahoMesh preset to the MQTT bridge implementation, increasing the total number of built-in presets. Updated the CLI to support listing available MQTT presets with pagination, improving user experience when configuring MQTT connections. Adjusted related documentation to reflect these changes.
Reintroduced the 'origin' field in the buildPacketMessage function to its original position within the JSON object. This adjustment ensures consistency in the message format and aligns with previous structural changes made to enhance clarity.
Updated the buildPacketMessage function to improve the structure of the JSON object being built. The 'origin_id' field has been moved to a later position, and the 'hash' field has been added to enhance the packet's metadata. This change aims to streamline the message format for better clarity and consistency.
Changed the default setting for TX packets from disabled to 'advert' across multiple files, including documentation and example implementations. This aligns the behavior of the MQTT bridge with the new default preferences, ensuring that only the node's own advert packets are uplinked by default. Updated relevant comments and documentation to reflect these changes.
Introduced two new environments in platformio.ini for the Heltec V4 expansion kit: `heltec_v4_expansionkit_repeater_observer_mqtt` and `heltec_v4_expansionkit_room_server_observer_mqtt`. Each environment includes specific build flags, dependencies, and source filters tailored for MQTT functionality, enhancing the project's capabilities for IoT applications.
Introduced a new CLI command to view and set the radio watchdog interval, allowing users to configure the watchdog timeout in minutes (0 to disable, 1-120 for active). Updated the documentation to reflect this addition and clarified the parameters for the `neighbor.remove` command. Default watchdog interval is set to 5 minutes in the codebase.
Updated the formatting of MQTT preset entries in MQTTPresets.h for improved readability and consistency. No functional changes were made to the preset definitions.
Match upstream pin map (KCT8103L CSD/CTX, I2C 6/17, LORA_TX_POWER=9) and restore meshcore LoRaFEMControl.cpp and HeltecTrackerV2Board.cpp. Run ESP32 at 240MHz for MQTT/WiFi bridge headroom. Sensor env drops fork-only ENV_PIN overrides to match upstream.
Made-with: Cursor
Upstream adds LoRaFEMControl for a KCT8103L pinout; this variant uses GC1109 (P_LORA_PA_*). Reintroduce the class with the same API and wire HeltecTrackerV2Board through it so FEM logic matches platformio.ini.
Made-with: Cursor
Update the PsychicMqttClient to ensure that QoS0 messages are enqueued with durable outbox storage. This change addresses issues with false-failure semantics in certain connected paths, improving message flow reliability. Additionally, modify platformio.ini to include SSL certificate generation and adjust build flags for reduced verbosity and enhanced functionality.
Update the PsychicMqttClient to set a _config_dirty flag whenever a configuration setter is called. This ensures that the MQTT configuration is only applied when changes are made, optimizing the connect and reconnect processes. Added logging to indicate whether the configuration was updated or unchanged.
Refactor the MQTTBridge to implement enhanced QoS handling for publish operations. Introduce retry mechanisms for QoS0 packets, allowing for transient failures to be retried with a delay. Update publish methods to return success status, improving error handling and logging. Additionally, adjust the packet queue processing to accommodate new retry logic and ensure better message delivery control.
Eliminate legacy support for mqtt.server, mqtt.port, mqtt.username, and mqtt.password in the CommonCLI. This streamlines the command handling process and aligns with the updated configuration management.
Made-with: Cursor
Battery (TechoBoard.h/cpp): Added PIN_VBAT_MEAS_EN (P0.31) — the T-Echo
Lite has a gated voltage divider that must be enabled before reading. Also
added pinMode(PIN_VBAT_READ, INPUT) before each ADC read to reclaim P0.02
from other peripherals. Pin definitions hardcoded from LilyGo's
t_echo_lite_config.h.
I2C (variant.h): Corrected SDA/SCL from P0.04/P0.02 to P1.04/P1.02 per
LilyGo's IIC_1_SDA/IIC_1_SCL. The old P0.02 mapping conflicted with the
battery ADC pin.
GPS (variant.h): Corrected all five GPS pin assignments to match LilyGo's
config — UART TX/RX, wake, PPS, and power enable were all scrambled.
SPI (variant.h): Fixed SPI_INTERFACES_COUNT from _PINNUM(0, 2) to (2).
Tested on T-Echo Lite Non-Shell (USB-C, no display). Battery readings match
Heltec V4 reference within 10mV.
T-Echo Lite Non-Shell has no ePaper display, but the existing
companion BLE env inherits DISPLAY_CLASS=GxEPDDisplay from the base
env. This causes display.begin() to run on non-existent hardware,
corrupting BLE initialization and generating a random PIN that
cannot be displayed, making BLE connection impossible.
Add LilyGo_T-Echo-Lite_non_shell_companion_radio_ble env that:
- excludes DISPLAY_CLASS and ePaper-related build flags
- removes GxEPDDisplay.cpp and ui-new from build sources
- uses static BLE_PIN_CODE=123456 (avoids random PIN generation)
Also fix boards/t-echo.json:
- add nrfutil to upload protocols list
- add use_1200bps_touch=true and wait_for_upload_port=true
to enable reliable flashing via PlatformIO upload button
This is a medium-ish refactor to attempt to clean up sensor handling logic both for board stability and future potential growth before the code becomes all spaghetti and meatballs.
I'd be curious to see if anyone running sensors out there that knows how to build and flash MeshCore code could give this a try and see how it behaves. It is working fine on my end on multiple nodes.
PR notes are gigantic because it is a fundamental behavior repair for sensors, so I wanted to over-explain. Also, if it hadn't been mentioned previously, push-back is always welcome. I'm just spending my time trying to clean up / fix / enhance this corner of the firmware, and want to contribute my improvements back to the project.
**Problem:**
Current MeshCore code makes no attempt to see what sensors are actually available on the I2C bus at startup and blindly tries to interact with sensors. This has some very bad side-effects, like if a sensor that is unsupported, or has a weird initialization process, the MeshCore node will just hang at boot and never successfully start up and ostensibly looks bricked, or the INA226 and SHT4X both sharing the same address and the code just silently fighting.
The current implementation also gloms sensor readouts from the MCU and environment sensors onto the same telemetry channel, with some arbitrary exceptions for incrementing channels based on certain behavioral situations. The MCU temperature and external temperature sensors would appear on channel 1, and it wouldn't be possible to tell which sensor the temperature value was coming from.
Per [CayenneLPP](https://github.com/myDevicesIoT/CayenneLPP): *Data Channel: Uniquely identifies each sensor in the device across frames, eg. “indoor sensor”* So this channel division implementation falls inline with what CayenneLPP intended. There are up to 256 channels available. So I tried to model this change in that behavioral style.
**Proposed Improvement:**
This implementation scans the I2C bus for what devices are present, sets each sensor to its own CayenneLPP channel, and keeps MCU telemetry on channel 1 only. So Channel 1 is always "self" and no confusion can result.
Details:
- Channel 1 is always the MCU and things about it, so you always know that telemetry is from the board itself. Exception is GPS, GPS stays on channel 1 as well since it is "about the board" even though it's a bit gray-area as GPS can often be a secondary chip.
- Each sensor board is allocated to a dedicated CayenneLPP channel, so if you are reading from that channel, you know the data is from that sensor only. (Sensors emitting more than one of the same type of measurement are exceptions.)
- `scanI2CBus()` probes addresses 0x08–0x77 with raw `beginTransmission`/`endTransmission`. No sensor library is touched until after this completes. This will prevent sensor-based boot hangs, unknown or unresponsive devices never reach a library init call.
- Created `SENSOR_TABLE` a compile-time array that is gated by the existing `ENV_INCLUDE_*` macros. A sentinel `{ 0, nullptr, nullptr, nullptr }` at the end keeps the array non-empty regardless of which sensors are enabled, avoiding zero-length array warnings.
- When `begin()` is called, scan first, then loop: skip if address not detected, skip if `init()` returns 0, otherwise register one ActiveSensor entry per sub-channel.
- `querySensors()` I replaced the entire #ifdef chain with a 3-line loop.
- T1000-E has its own T1000SensorManager, so it should be completely unaffected by this change.
- SHT4X quirky initialization behavior is retained.
- MLX90614 - git commits around this didn't have any notes as to why it is reporting ambient temperature on a separate channel as well as the object temperature, as the ambient temperature is used internally to compute the object temperature and not really needed for the sensor's purpose - just the same, kept the existing behavior of reporting the ambient temperature one channel above the channel assigned to the sensor
- All `bool *_initialized` fields are gone, replaced with `ActiveSensor _active_sensors[16]` (query function pointer and sub-channel index) and `_active_sensor_count. SensorDef` lives entirely in the `.cpp` so the header has no dependency on it.
- Details on the INA226 and SHT4X: both default to address 0x44, the old code had a bug and would have both begin() calls fire and they would just fight each other silently. In the new code, the respective sensor code is only called if the device is actually present, however, if both were present simultaneously, SHT4X comes first in the table and would win, and INA226 would return false and be skipped. The INA226 has 16 possible addresses that are configurable in the hardware itself, so in a potential scenario where both sensors would be present, the person implementing that design could take that into account.
- BME680 gas resistance will now transmit on the same channel as the rest of BME680 telemetry which is inline with CayenneLPP standards. Coupling this PR with https://github.com/meshcore-dev/MeshCore/pull/2146 streamline the whole sensor telemetry, and with https://github.com/meshcore-dev/MeshCore/pull/2149 will overall improve BME680 handling. The gas resistance sensor actually has a binary library to make it more useful, calibration, accounting for age of sensor, and other improvements, but since that adds more flash consumption, I have omitted that in PRs thus far.
- RAK12035 and other current upstream dev branch changes integrated.

The Waveshare RP2040-LoRa board has an RF switch with two complementary
control lines:
- DIO2 (CTRL) -- driven automatically by the SX1262 chip: HIGH on TX,
LOW on RX
- GPIO17 (!CTRL) -- was not configured in MeshCore, so it floated and
the switch never properly selected the LNA/RX path
Without this pin driven, the RF switch never switches to RX mode,
resulting in completely degraded reception. TX was unaffected because
DIO2 alone is sufficient to activate the TX path.
Adding SX126X_RXEN=17 lets RadioLib drive GPIO17 as the complement of
DIO2, so the switch correctly routes the signal to the LNA on receive.

This commit introduces a new `reconnect` method in the `PsychicMqttClient` class, allowing for re-establishing a connection to the MQTT broker without needing to disconnect first. The method checks if the client is initialized, updates the configuration if necessary, and attempts to reconnect, enhancing the overall connection management. Additionally, the MQTT slot management has been updated to support up to 6 configurable slots, improving flexibility in connection handling.
The companion_radio example was not restoring the GPS enabled/disabled
preference from flash after reboot. The preference was being saved
correctly when toggled via the mobile app, but on boot,
sensors.begin() -> initBasicGPS() unconditionally sets gps_active=false
and nothing subsequently restored the persisted state.
Added applyGpsPrefs() (matching the pattern in simple_repeater,
simple_sensor, and simple_room_server) and call it from main.cpp
after sensors.begin() to ensure the GPS hardware is initialized
before the saved preference is applied.
As @LitBomb pointed out in his [comment](https://github.com/meshcore-dev/MeshCore/issues/2118#issuecomment-4108168109) on #2118 RX Boosted Gain should not be enabled for the Station G2.
This change is a fix for #2124 to make the default of `radio.rxgain` to be OFF on the Station G2.
This restores the pre-1.14.1 behaviour with the only change being the user is now able to change the setting in the CLI.
Reverted prior dev merge, then merged current meshcore-dev dev. Resolved
CommonCLI by restoring MQTT prefs flow with upstream com_prefs layout
(rx_boosted_gain at offset 79), rxgain CLI, poweroff/shutdown, and FEM
variant files from upstream.

The signed comparison in countBefore breaks for the max uint32_t value.
Even though callers now use getOutboundTotal(), the function itself
should be correct for all inputs.
On the T114, GPS_RESET (pin 38) is the same pin as PIN_3V3_EN.
MicroNMEALocationProvider::begin() sets pin 38 HIGH (powering the 3V3
rail) but stop() never set it back LOW, leaving the GPS module powered
even when disabled.
Assert reset pin in stop() to mirror begin(), and guard
_location->loop() behind gps_active check.

which independently controls GPS power via GPS_EN and shares VEXT with

The RAK13302 1W module uses a Skyworks SKY66122-11 front-end module with
three digital control pins (CSD, CTX, CPS) that must be actively driven
by the host MCU. The previous code only managed CTX (GPIO 31) — toggling
it for TX/RX — but never initialized CSD (GPIO 24) or CPS (GPIO 21),
leaving them floating with no pull-up/pull-down resistors on the PCB.
With floating CSD and CPS, the SKY66122 was in an undefined operating
mode:
- The 30 dB TX PA may not have been reliably engaging
- The 16 dB RX LNA was never reliably active, degrading receive
sensitivity
The GC1109 FEM needs its VFEM_Ctrl pin held HIGH during deep sleep
to keep the LNA active, enabling proper RX sensitivity for
wake-on-packet. Without this, the LNA is unpowered during sleep
and RX wake sensitivity is degraded by ~17dB.
Release RTC holds in begin() after configuring GPIO registers
(not before) to ensure glitch-free pin transitions on wake.
Trade-off: ~6.5mA additional sleep current for significantly
improved wake-on-packet range.
Instead of overloading getOutboundCount() with a magic sentinel value,
add a dedicated getOutboundTotal() method to the PacketManager interface
that returns the total queue size without time filtering.
This eliminates the fragile convention that caused the regression and
makes the two operations — time-filtered count vs total count —
explicitly separate in the API.
PR #1795 changed PacketQueue::countBefore() to use signed 2's complement
arithmetic for millis wraparound safety. However, this broke the
0xFFFFFFFF sentinel pattern used by callers to mean "count all packets
regardless of schedule".
With the signed comparison, countBefore(0xFFFFFFFF) always returns 0,
causing hasPendingWork() to report false and repeaters to sleep with
packets still queued. Stats reporting also shows queue_len as 0.
Add an early-return for the sentinel value before the loop, and document
the sentinel convention on the virtual interface and implementation.

The table of contents of `docs/faq.md` had at the end a bogous entry
```markdown
- [| | High Output | 22 dBm | 28 dBm | |](#--high-output--22-dbm--28-dbm--)
```
This patch removes that bogous entry.
Added to section 5.14 "Are there are projects built around MeshCore?":
* awesome-meshcore
* meshcore-open
* MeshCore-Cardputer-ADV
* LunarCore
* MC-Term
* Meck
* Meshcore for Wio Tracker L1 Pro

* companion: new field in CMD_SET_OTHER_PARAMS, path_hash_mode
* companion: CMD_SEND_SELF_ADVERT, cmd_frame[1] now holds the path hash size (0 = zero hop, 1..3 = flood path hash size)
PacketQueue::countBefore() and PacketQueue::get() use unsigned
comparison (_schedule_table[j] > now) to check if a packet is
scheduled for the future. This breaks when millis() wraps around
after ~49.7 days: packets scheduled just before the wrap appear
to be in the far future and get stuck in the queue.
Use signed subtraction instead, matching the approach already used
by Dispatcher::millisHasNowPassed(). This correctly handles the
wraparound for time differences up to ~24.8 days in either
direction, well beyond the maximum queue delay of 32 seconds.
Tested in v1.13.
These commands don't work anymore:
```
get password
-> ??: password
set password secret
-> unknown config: password secret
```
This does work:
```
password secret
-> password now: secret
```
PacketQueue::add() silently dropped packets when the queue was at
capacity. The packet pointer was lost — never enqueued, never returned
to the unused pool. Each occurrence permanently shrank the 32-packet
pool until allocNew() returned NULL and the node went deaf. Return bool
from add() and free the packet back to the pool on failure.
This change addresses two issues. The first is that the
LilyGo_TLora_V2_1_1_6_terminal_chat build would try to compile
simple_repeater/MyMesh.cpp. All other examples of terminal chat
targets are instead building simple_secure_chat/main.cpp . This
change would align this build to the rest of the builds.
The second issue, found during the course of investigating the
first, stems from simple_repeater/MyMesh.cpp using the
MAX_NEIGHBOURS #define to control whether the neighbor list is kept.
Repeaters that keep this list must define this value, and if the
value is not defined, then all neighbor-related functionality is
compiled out. However, the code that replies to
REQ_TYPE_GET_NEIGHBOURS did not properly check for this #define,
and thus any target that compiles simple_repeater/MyMesh.cpp
without defining MAX_NEIGHBOURS would get an undefined variable
compilation error.
As a practical matter though, there are no targets that compile
simple_repeater/MyMesh.cpp AND do not define MAX_NEIGHBOURS,
except this build due to the first issue. As a result, the
second issue is addressed only as a matter of completeness. The
expected behavior with this change is that such a repeater would
send a valid reply indicating zero known neighbors.

- Refactored WiFi monitoring logic into a dedicated function to streamline the mqttTaskLoop.
- Introduced fragmentation recovery logic to handle memory pressure more effectively, ensuring MQTT clients are recreated when necessary.
- Reset reconnect backoff attempts upon successful connection to the main broker.
These changes aim to improve the stability and performance of the MQTTBridge under varying network conditions.
- Introduced PSRAM-aware memory allocation functions (`psram_malloc` and `psram_free`) to optimize memory usage on ESP32 boards with external RAM.
- Updated MQTTBridge initialization to allocate JWT token buffers and raw data storage in PSRAM when available.
- Enhanced FreeRTOS queue creation to utilize PSRAM for storage, improving memory efficiency.
- Implemented dynamic allocation for JSON buffers in PSRAM during status publishing and packet handling, reducing stack usage.
- Ensured proper memory cleanup for PSRAM allocations in the `end` method to prevent memory leaks.
This update aims to enhance performance and stability in memory-constrained environments by leveraging available PSRAM resources.
- Implemented PSRAM availability checks and logging to assist in debugging memory fragmentation on boards with external RAM.
- Enhanced logging to provide detailed information about PSRAM size, free memory, and initialization status.
- Updated platformio.ini files across multiple variants to remove obsolete mbedTLS configuration flags, streamlining the build process.
- Added new build flags for mbedTLS: CONFIG_MBEDTLS_ASYMMETRIC_CONTENT_LEN, CONFIG_MBEDTLS_SSL_IN_CONTENT_LEN, and CONFIG_MBEDTLS_SSL_OUT_CONTENT_LEN.
- These changes improve the handling of SSL content lengths, optimizing performance for various hardware variants.
- Updated source filters to include MQTTBridge and MQTTMessageBuilder in relevant configurations.
- Added memory debugging features to log heap usage and fragmentation recovery for MQTT clients.
- Introduced `recreateMqttClientsForFragmentationRecovery()` to manage MQTT client lifecycles and reduce memory fragmentation.
- Updated critical memory checks to log detailed heap statistics and active MQTT client counts.
- Included new debug logging for memory status every 60 seconds when memory debugging is enabled.
This update aims to improve stability and performance in memory-constrained environments.
- Trigger noise floor calibration every 2s and AGC reset every 30s in main loop.
- Reorder loop to match Dispatcher: calibrate + radio.loop() before AGC reset
and recvRaw() so RSSI is never sampled right after startReceive().
- Update protocol doc with calibration intervals and typical noise floor range.
- Variant platformio.ini updates (heltec_v3, rak4631).
- Main broker: only allocate _mqtt_client when custom broker configured
(analyzer-only saves one PsychicMqttClient). Reconnect main broker after
forced disconnect with 30s throttle; set last_attempt on disconnect so
throttle applies and avoids reconnect storms on flaky WiFi.
- Analyzer clients: call disconnect() when WiFi transitions to disconnected
so ESP-IDF frees MQTT buffers (it does not free on WiFi drop). Reduces
fragmentation and Max drop after disconnect/reconnect cycles.
- get wifi.status: report WiFi uptime (Xd Xh Xm Xs) when WITH_MQTT_BRIDGE.
Track connect time in bridge; backfill when already connected at first check.
- get mqtt.status: show msgs on/off, broker (connected/disconnected/n/a),
analyzer US/EU (connected/disconnected/off), and queue count.
Note: PsychicMqttClient change (register event only on first client creation)
belongs in the library repo if committed separately.
- Updated comments to specify that the Dispatcher owns the packet memory and should handle freeing.
- Removed unnecessary calls to free queued packets in the MQTTBridge, ensuring only references are discarded.
- Enhanced code clarity regarding packet lifecycle management in the end and processPacketQueue methods.
- Introduced `getPacketsRecvErrors()` method in `Dispatcher` to track receive errors.
- Updated `buildStatusMessage()` in `MQTTMessageBuilder` to include `recv_errors` parameter.
- Modified `publishStatus()` in `MQTTBridge` to retrieve and send receive error statistics.
- Adjusted `RadioLibWrappers` to override `getPacketsRecvErrors()` for consistency.
When DISPLAY_CLASS is defined via build flags but HELTEC_LORA_V4_OLED
or HELTEC_LORA_V4_TFT flags aren't set, include SSD1306Display.h as
fallback. This fixes compilation errors for environments like
heltec_v4_repeater_observer_mqtt that extend Heltec_lora32_v4 directly
and set DISPLAY_CLASS=SSD1306Display.
Updated the variable name from _max to _max_size in the BufStream class to improve code readability and maintainability. This change ensures consistency in naming conventions within the class.
This change counts when readData returns an err code other than RADIOLIB_ERR_NONE. In most cases this is going to be a CRC error. This counter is exposed in the `stats-packets` command, and in the repeater stats payload (4 additional bytes to the payload, which is now 56 bytes with this change. My incompetent robot claims the total payload size is 96 bytes (unverified but probably close).

- Removed aggressive health checks that caused connection instability, relying on the MQTT client library for connection management.
- Updated status publishing to verify connection state before attempting to publish, ensuring accurate broker status.
- Moved MQTT processing to a dedicated FreeRTOS task on Core 0, enhancing non-blocking behavior.
- Implemented a FreeRTOS queue for thread-safe packet handling, replacing the previous circular buffer approach.
- Updated WiFi initialization and connection management to occur within the FreeRTOS task, improving overall system responsiveness.
- Enhanced logging and error handling for MQTT connections and packet processing.
- Cached broker and analyzer server statuses to reduce redundant checks and improve efficiency.
- Added conditional compilation for WiFi power save settings in setMQTTPrefsDefaults.

- Set default WiFi power save mode to 1 (none) when not explicitly defined, enhancing flexibility for different hardware setups.
The ntc_temp2 lookup table was declared as 'char', which can be
unsigned on some platforms, causing negative temperature values
(-30°C to -1°C) to be incorrectly interpreted.

- Introduced new commands for retrieving statistics: CMD_GET_STATS_CORE, CMD_GET_STATS_RADIO, and CMD_GET_STATS_PACKETS.
- Implemented corresponding response handling methods to format and send statistics data.
- Updated MyMesh constructor to initialize new member variables for managing statistics.

* repeater: onControlDataRecv(), now responds to new CTL_TYPE_NODE_DISCOVER_REQ (zero hop only)
* node prefs: new discovery_mod_timestamp (will be set to affect when node should respond to DISCOVERY_REQ's )
- Added formatStatsReply, formatRadioStatsReply, and formatPacketStatsReply methods in MyMesh for both simple_repeater, simple_room_server, and simple_sensor.
- Updated CommonCLI to handle new stats commands.
* MomentaryButton: new constructor 'multiclick' param

it seems that if the LR1110 radio hears a packet corrupted in a specific way, it'll report a packet of 0 length and with the header error IRQ set. every packet received afterwards will then be shifted to the right by 4 bytes on top of the radio's reported offset. this can occur multiple times with the shift increasing by 4 bytes each time. thus, this patch will read from an additional offset after hearing the trigger packet.
transmitting seems to reset the shift - unsure exactly what operation resets it but standby() is called after tx so patch assumes shift is 0 after standby(). more investigation may be needed here.

- Include actual node altitude in GPS telemetry instead of hardcoded 0.0f
- Extract altitude data from both ublox_GNSS and serial GPS sources

This is a key difference compared to other systems and I see people
asking this a lot. It is mentioned in the FAQ but let's make it more
prominent in the README.
This commit introduces several improvements to the SerialBridge helper:
- Adds support for the nRF52 platform by implementing the `setPins` configuration.
- Corrects the type cast for the RP2040 platform from `HardwareSerial` to `SerialUART`.
- Refactors packet deserialization to use a new `Packet::readFrom()` method instead of a direct `memcpy`, improving encapsulation.
- Updates the packet length validation to use the more appropriate `MAX_TRANS_UNIT` constant.
Implement a "seen packets" table to track packets that have already been processed by the serial bridge.
This prevents packets from being re-transmitted over the serial link if they have already been seen, and it stops inbound packets from serial from being re-injected into the mesh if they are duplicates.
Duplicate inbound packets are now freed to prevent memory leaks.
This commit refactors the serial bridge functionality out of the `simple_repeater` example and into a more reusable, object-oriented structure.
An `AbstractBridge` interface has been introduced, along with a concrete `SerialBridge` implementation. This encapsulates all the logic for packet framing, checksum calculation, and serial communication, cleaning up the main example file significantly.
The `simple_repeater` example now instantiates and uses the `SerialBridge` class, resulting in better separation of concerns and improved code organization.
Updates the manufacturer identifier with the EBYTE module. Makes the LED

Adds a new variant 'ikoka_stick_nrf' and associated support files. This is
based on the Xiao nRF54 code with pin numbers and functions changed to suit the
differences in hardware between the WIO SX1262 board and the Ikoka Stick.
Sets the default LoRa transmit power to 9dBm to avoid burning up the frontend
in Ikoka Sticks equipped with the Ebyte 33dBm S22 module on first boot.
Adds support for an SSD1306 display connected to the display header. Note the
display pinout is the same as the RAK4631 display header so make sure to use a
display wired accordingly (aliexpress etc. SSD1306s typically have Vcc & GND
reversed from what this board expects).
Adds support for display rotation to SSD1306Display via a platformIO define.
This support was added following the same paradigms found elsewhere in the code
for rotating a display.

-Reduced delay time within the RAK gps init sequence
Changes to migrate sensor code to the ESM.
Added a separate GPS init sequence for the RAK that scans I2C and Serial1 on the various sockets of the various base boards to find the RAK12500. (and soon the RAK12501)
Removed the GPS specific envs from platformio.ini and enabled GPS for all envs.
Verified working with RAK12500 on RAK19007 sockets A and D, as well as RAK19003.

* special CLI command, "setperm {pubkey-hex} {permissions-int16}" for admin(s) to manage user access (permissions 0 = remove)
Replaced use of `restartOnDisconnect(true)` with explicit (existing) manual re-advertising logic.
This avoids Bluetooth stack instability caused by overlapping advertising state,
Changes:
- Added explicit `Bluefruit.Advertising.stop()` and data clears in `startAdv()`
- Disabled automatic restart with `restartOnDisconnect(false)`
- Re-advertising now fully handled in `checkRecvFrame()` loop
Tested on: iPhone, Android, Windows, and Chrome – confirmed stable reconnects and name visibility.
Pin 45 and 46 are strapping pins on ESP32-S3, which can lead to unintended consequences on boot. I have amended the pins and added an enable pin as well.
Removed the call to Bluefruit.ScanResponse.addName() in startAdv(), as it was preventing BLE from reliably restarting advertising after a disconnect.
Hypothesis: adding the device name to the scan response exceeds internal buffer limits or causes a conflict with advertising timing, leading to the BLE stack silently failing to re-advertise.
Tested successfully (on T-1000) without this line, advertising now resumes correctly after disconnection (on Iphone)
repeaters do not typically have user buttons and
there is only one analog pin available on most, if
not all, base boards. so this allows repeaters to

IAQ readout is still a work in progress, but a placeholder can be seen on Channel 2 of the app telemetry.
There is a lot to this PR, so if there are any questions let me know.
The idea here is to merge T-Beam fw so that there is less redundant code. Most versions (except the 0.7) share PMU code, init sequence, and most IO pin definitions.
- Merged all T-Beam board.h files into one TBeamBoard.
- Added PMU code to identify different AXP chips.
- Modified "lilygo tbeam SX1276" variant to cover all T-Beam SX1276 versions
- Modified "lilygo tbeam SX1262" variant to cover all T-Beam SX1262 versions
- Enabled GPS on all T-Beam versions/models
- Enabled BME280 on the Supreme
I am also updating EnvironmentSensorManager to allow for boards that do or don't have GPS enable pins, as well as a PERSISTANT_GPS define check for boards that want GPS to stay active after boot.
GPS support via EnvironmentSensorManager. Connect GPS RX to pin 45, TX to pin 46.
Note that while you can disable using the GPS there is no way to power down the GPS without using a mosfet and adjusting PIN_GPS_EN.
Adds `_alert[80]` which can be set along with `_needs_refresh`
to trigger a simple on screen alert that lasts 1s at this time.
Implements POC with double press to advert action
Pulled the class out of main.cpp, made a header to go along with it, externed globals in headers to make them accessible to button code. Added button code to send an advert on double press. Refactored ini files to prevent linker errors.
Added a new UITask shutdown method to run non-board specific shutdown code. This avoids having to update all the board files for different hardware.
UITask::shutdown(bool restart = false);
Where the buzzer is available and defined, the RTTTL shutdown melody is played when the button is held down for >5s.
Added RAK12500 GPS support
Added socket scan capability to determine which socket the GPS is connected to
T-beam supreme: added conditional to displaying location data to only when gps is active

This document describes MeshCore repeater fault alerts, including configuration, CLI commands, and operational behavior.
The repeater can broadcast a one-line fault notification on a configured group channel when WiFi or any active MQTT slot has been disconnected longer than a configurable threshold.
The alert is sent over **LoRa** as a `PAYLOAD_TYPE_GRP_TXT` flood packet on the configured channel (with sender = device name) - *not* over MQTT. This is intentional: the MQTT path is what's broken, so the only working delivery is the mesh itself. Anyone in radio range subscribed to the same channel/hashtag in their companion app will see the alert inline with normal channel chat.
> **A small list of community channels is intentionally NOT supported.** Fault alerts are operator-infrastructure noise - broadcasting them on shared community channels would spam every node in the area (and on `#test` / `#bot` would amplify via well-known auto-responders). The currently banned destinations are:
>
> - The well-known **Public** group PSK (`izOH6cXN6mrJ5e26oRXNcg==`)
> - **`#test`** (`sha256("#test")[0..15]`)
> - **`#bot`** (`sha256("#bot")[0..15]`)
>
> The list lives in `BANNED_ALERT_CHANNELS[]` in [src/helpers/AlertReporter.cpp](src/helpers/AlertReporter.cpp); adding a new entry is one line (label + 32 hex chars). The matcher runs at both the CLI validation step (`set alert.psk`, `set alert.hashtag`) and the alert-send path, so a saved-config bypass is still refused at runtime. You must point alerts at a **private PSK** (`set alert.psk`) or a non-banned **hashtag channel** (`set alert.hashtag`) before alerts can fire.
## Scope and routing
Alert floods ride the **repeater's default scope** by default (the same TransportKey used for adverts and channel broadcasts - set via `region default ...`). Operators can override on a per-alert-feature basis with `set alert.region <name>`:
- If `alert.region` is set and the name resolves via `RegionMap`, that region's TransportKey is used.
- If `alert.region` is unset, or the name doesn't resolve, the repeater's `default_scope` is used.
- If both are null, the alert is sent unscoped (matches the pre-scoped firmware's behavior).
`alert.region` is stored as-is - it does **not** create the region. Use `region put <name>` first if it doesn't exist.
## What triggers an alert
- **WiFi**: continuously down for at least `alert.wifi` minutes (default 30)
- **MQTT slot N**: enabled, has connected at least once since boot, and has been disconnected for at least `alert.mqtt` minutes (default 240, i.e. 4 h)
A "recovered" message is sent once when the underlying connection comes back. After firing, a fault is rate-limited by `alert.interval` (default 60 minutes) before it can re-fire - this prevents flapping links from spamming the channel.
| `alert.psk` | *(unset)* | Private channel secret as **32 hex chars** (16-byte channel key) - the same format the mobile app's "Share Channel" emits, and what every other secret-shaped CLI command (e.g. `prv.key`) uses. |
| `alert.hashtag` | *(unset)* | Informational only; set via `set alert.hashtag` to pre-derive `alert.psk` from `sha256("#name")[0..15]`. Cleared when `alert.psk` is set directly. |
| `alert.region` | *(unset)* | Optional region name; overrides the repeater's `default_scope` for alert sends only. Empty = use `default_scope`. Looked up lazily via `RegionMap`; unknown names silently fall back to `default_scope`. |
| `alert.interval` | `60` (min) | Minutes between repeat alerts of the same fault. **Hard floor of 60 min** so a flapping link can't spam the mesh; the CLI rejects lower values and AlertReporter clamps stale prefs at runtime. |
> `alert.psk` is unset on a fresh flash. **Alerts cannot fire and `alert test` will refuse to send until you configure either `alert.psk` directly or `alert.hashtag` (which derives one).** The sender shown on outgoing alert messages is always the node name (`set name ...`); there is no separate `alert.name`.
## CLI
Get:
-`get alert` - master on/off
-`get alert.psk` - the active 32-hex-char PSK (or `(unset)`) (**serial console only**)
-`get alert.hashtag` - the originating hashtag (or `(unset)`, e.g. after `set alert.psk` overrides the hashtag-derived key)
-`set alert.psk <hex>` - 32 hex chars (16-byte channel secret); rejects banned channels (Public, `#test`, `#bot`). Paste the mobile app's "Share Channel" output as-is. Clears `alert.hashtag` since the new key is operator-supplied.
-`set alert.psk` (no argument) - clears both `alert.psk` and `alert.hashtag`
-`set alert.hashtag <name>` - derives the 16-byte key from `sha256("#name")`*once*, stores it as `alert.psk`, and remembers the hashtag for `get alert.hashtag`. `#` prefix is added if omitted (so `alerts` and `#alerts` are equivalent). Refuses banned hashtag names.
-`set alert.hashtag` (no argument) - clears both `alert.psk` and `alert.hashtag`
-`set alert.region <name>` - alert-only scope override (no region-map mutation; unknown names silently fall back to `default_scope`)
-`set alert.region` (no argument) - clear override, use `default_scope`
-`set alert.interval <minutes>` (60-10080; 60-minute floor to protect mesh airtime)
Action:
-`alert test` - send a one-off `[test] alert channel ok` immediately on the configured channel; ignores `alert on/off` so operators can verify the channel before enabling fault firing. Returns an error if no channel is configured.
-`alert test <message>` - send a custom test message: `[test] <message>`.
## Example: dedicated hashtag channel (recommended for operator groups)
```bash
set alert.hashtag ops-alerts # stored as "#ops-alerts"; key = sha256("#ops-alerts")[0..15]
set alert.wifi 10# tighter for ops monitoring
set alert.mqtt 60
set alert on
alert test
```
Anyone running a companion app and subscribed to the `#ops-alerts` hashtag channel will see the alerts inline.
## Example: dedicated alerts channel with a private PSK
Generate a 16-byte random PSK as 32 hex chars (`openssl rand -hex 16`), or use the companion app's "Add channel" feature and copy the "Share Channel" output. Then:
```bash
set alert.psk <32_hex_chars> # 16-byte channel secret; mobile "Share Channel" pastes in directly
set alert.wifi 10
set alert.mqtt 60
set alert on
alert test
```
Subscribers running a MeshCore companion app should add a channel with the same PSK; alerts will appear in that channel's chat view. (Pick any local name for it - the sender of incoming alert messages is the repeater's node name.)
## Sample messages
```
MyObserver: WiFi down 47m (reason 201)
MyObserver: WiFi recovered after 1h3m
MyObserver: MQTT slot 1 (analyzer-us) down 4h12m
MyObserver: MQTT slot 1 (analyzer-us) recovered after 4h45m
```
## Notes
- A reboot during an outage resets the timer; the alert won't double-fire because `millis()` starts at 0 at boot. The fault must persist `alert.wifi` / `alert.mqtt` minutes from boot.
- Fault state is stored in RAM only - no persistence across reboots.
- The MQTT-slot watcher uses a separate per-slot `current_outage_started_ms` field that is reset on each reconnect, distinct from the `first_disconnect_time` shown in `mqttN.diag` (which remains a "first disconnect since boot" counter for diagnostics).
- WiFi-down alerts can only be delivered if the LoRa radio is up. There is no fallback path.
- Banned channels (Public, `#test`, `#bot`) are **rejected** at both `set alert.psk` / `set alert.hashtag` and at the alert-send path, so even if you somehow set one via a saved config file, the firmware will silently refuse to broadcast on it. To add another banned channel, append a row to `BANNED_ALERT_CHANNELS[]` in [src/helpers/AlertReporter.cpp](src/helpers/AlertReporter.cpp); the format is `{ "label", "32-lowercase-hex-chars" }` (compute as `printf '#name' | openssl dgst -sha256 | cut -c1-32`).
- Alerts are sent via `sendFlood` with the resolved TransportKey codes attached, so they appear on the configured scope just like other broadcast traffic. Operators monitoring a specific region need to be subscribed to that region's scope to hear alerts.

This document describes the MQTT bridge implementation that allows MeshCore repeaters to uplink packet data to multiple MQTT brokers.
## Quick Start Guide
### Essential Commands to Get MQTT Observer Running
**1. Flash the observer firmware to your device**
Use one of the observer build targets (e.g., `heltec_v4_repeater_observer_mqtt`). After flashing, connect to the device console via serial (115200 baud) or repeater login.
**2. Configure radio settings**
If this is a fresh flash or full erase, configure your radio parameters first. These must match other nodes in your mesh:
```bash
set radio 910.525,62.5,7,5
set tx 22
```
Format: `set radio <freq_MHz>,<bw_kHz>,<sf>,<cr>`
**3. Configure device identity**
```bash
set name MyObserver
set mqtt.iata SEA
```
If migrating from an existing node (e.g., a Raspberry Pi gateway), restore the private key to keep the same identity:
```bash
set prv.key <your_64_hex_char_private_key>
```
**4. Configure WiFi credentials** (value is the rest of the line; do not use quotes — see [WiFi Commands](#wifi-commands))
```bash
set wifi.ssid YourWiFiNetwork
set wifi.pwd YourWiFiPassword
```
**5. (Optional) Disable packet repeating**
If this observer is receive-only (e.g., using a PCB antenna in a location where repeating would be harmful), disable forwarding:
```bash
set repeat off
```
**6. Reboot to connect**
```bash
reboot
```
**7. Verify configuration**
```bash
get wifi.ssid
get bridge.enabled
get mqtt.rx
get mqtt.tx
get mqtt.origin
get mqtt.iata
get mqtt1.preset
get mqtt2.preset
get mqtt3.preset
get mqtt.status
```
**That's it!** The device will now:
- Connect to WiFi automatically
- Start uplinking mesh packets to configured MQTT brokers
- By default, publish to Let's Mesh Analyzer US (slot 1) and EU (slot 2)
- Use device name as MQTT origin (set automatically)
---
## Overview
The MQTT bridge implementation provides:
- Up to 6 MQTT connection slots with built-in presets
- Built-in presets for many community brokers (see the [preset table](#slot-based-preset-system) for the full list)
- Custom broker support with username/password authentication
- JWT (Ed25519 device signing) authentication for most preset brokers; TennMesh uses a fixed username/password (plain MQTT)
- WSS (WebSocket Secure), direct MQTT/TLS, and plain MQTT (TennMesh) transport
- Automatic reconnection with exponential backoff
- JSON message formatting for status, packets, and raw data
- Packet queuing during connection issues
- Automatic migration from old configuration format
## Architecture
### Slot-Based Preset System
The MQTT bridge uses a slot-based architecture with up to 6 concurrent connections. Each slot can be configured with a built-in preset or custom broker settings.
- With PSRAM: All slots can be active simultaneously
- Without PSRAM: Maximum 2 active TLS/WSS slots (each WSS/TLS connection requires ~40KB internal heap)
- If more slots are configured than the device supports, excess slots show as `(inactive)` in `get mqtt.status`
- Slot configurations are preserved in preferences — moving firmware to a PSRAM device activates all slots
## Build Configuration
To build the MQTT bridge firmware:
```bash
# Heltec V3
pio run -e Heltec_v3_repeater_observer_mqtt
# Heltec V4
pio run -e heltec_v4_repeater_observer_mqtt
# Station G2
pio run -e Station_G2_repeater_observer_mqtt
# LilyGo T-LoRa V2.1-1.6 (TTGO LoRa32 V1.0)
pio run -e LilyGo_TLora_V2_1_1_6_repeater_observer_mqtt
pio run -e LilyGo_TLora_V2_1_1_6_room_server_observer_mqtt
```
**TLora naming:** The env prefix `LilyGo_TLora_V2_1_1_6` is LilyGo’s **T-LoRa V2.1–1.6** board (SX1276); PlatformIO selects **`ttgo-lora32-v1`** (TTGO LoRa32 V1.0). **MQTT observer** envs extend a slim base **without**`sensor_base` so the image fits `min_spiffs`; **all other**`LilyGo_TLora_V2_1_1_6_*` targets still use optional I2C environmental sensors as before. The **`lilygo_tlora_c6`** variant is separate hardware (ESP32-C6).
**T-LoRa V2.1–1.6 MQTT observer — one WSS broker:** This hardware is **classic ESP32 without PSRAM**. Each WSS preset uses a full TLS stack and large contiguous heap allocations; **two active broker presets at once** typically fails the second connection (`mbedtls_ssl_setup` / `esp-tls``0x8017`, low `IntMax` in `memory`). **Treat these observer builds as supporting one active cloud preset:** configure the broker you need in `mqtt1` or `mqtt2`, and set the other slot to `none` (e.g. `set mqtt2.preset none`). Use PSRAM-capable boards if you need multiple simultaneous MQTT uplinks.
Some MQTT observer builds use a non-default partition table to accommodate the larger firmware size (MQTT libraries, TLS, cert bundle, etc.). **When a board's partition table changes, you must flash the merged firmware (`*-merged.bin`) the first time** so the new partition layout and bootloader are written together. After that initial flash, standard OTA or non-merged updates will work normally.
**NVS / settings when the partition layout changes**
Flashing a **full merged image** (`*-merged.bin` at offset `0x0`) writes a new bootloader **and** partition table. If that layout **differs** from what is already on the device, **NVS is typically wiped or invalidated** — expect to lose stored configuration (admin preferences, WiFi, MQTT slots, name, etc.) and reconfigure from scratch.
- **`LilyGo_TLora_V2_1_1_6_*_observer_mqtt`:** These use the **same**`min_spiffs.csv` layout as other MeshCore TLora builds, so moving between repeater / room server / MQTT observer does **not** require a different partition table for normal upgrades. **If you previously installed an older TLora MQTT observer that used `huge_app.csv`,** flashing this firmware switches back to `min_spiffs` — treat that as a **partition layout change** (merged flash; NVS may be reset). **If you install MeshCore on a device that used a non-MeshCore partition map,** the first merged flash can still **wipe** settings.
- **`Station_G2_*_observer_mqtt`** and **`LilyGo_TBeam_1W_*_observer_mqtt`**: These use `default_16MB.csv` to accomodate the larger size of the MQTT observer firmware. Installing MQTT observer firmware on these devices requires a **merged** flash the first time. The same applies if you move **from** firmware that was built with a **different** partition table—the first merged flash that installs this layout will **wipe** stored settings.
**How to flash the merged firmware:**
You can flash the merged firmware using either the web flasher or the command line:
- **Web flasher (recommended):** Use the [MeshCore Web Flasher](https://meshcore.io/flasher) to flash the `*-merged.bin` file directly from your browser — no tools to install.
- **Command line:**
```bash
# Build the merged binary
pio run -t mergebin -e LilyGo_T3S3_sx1262_repeater_observer_mqtt
# Flash at offset 0x0 (overwrites bootloader + partition table)
> **Note:** If the **partition layout is unchanged** (e.g. updating the MQTT observer build in place), device configuration in NVS is usually retained; Bluetooth pairings may still be cleared on some upgrade paths. If the **partition table is new to the device**, see **NVS / settings when the partition layout changes** above — stored settings are typically lost. After the first merged flash **for a given layout**, subsequent updates on that board can use OTA or the standard non-merged binary when applicable.
Optional PlatformIO `build_flags` override defaults written when `/mqtt_prefs` is first created. They do **not** change existing saved prefs on upgrade or reflash (unless `/mqtt_prefs` is erased).
| Macro | Default | Notes |
|-------|---------|-------|
| `MQTT_DEFAULT_SLOT1_PRESET` … `MQTT_DEFAULT_SLOT6_PRESET` | slots 1–2: `analyzer-us` / `analyzer-eu`; slots 3–6: `none` | Must be a built-in preset name, `none`, or `custom` |
| `MQTT_DEFAULT_IATA` | (empty) | e.g. `'"YYZ"'` |
| `MQTT_DEFAULT_TIMEZONE` | (empty) | e.g. `'"America/Toronto"'` |
| `MQTT_DEFAULT_TIMEZONE_OFFSET` | `0` | Fallback hours when TZ string is empty |
Example community build:
```ini
build_flags =
-D MQTT_DEFAULT_SLOT1_PRESET='"meshcore-ca-1"'
-D MQTT_DEFAULT_SLOT2_PRESET='"meshcore-ca-2"'
-D MQTT_DEFAULT_IATA='"YYZ"'
-D MQTT_DEFAULT_TIMEZONE='"America/Toronto"'
-D MQTT_DEFAULT_TIMEZONE_OFFSET=-5
```
WiFi SSID/password are not compile-time configurable (operators set them per device via CLI).
Legacy `get mqtt.analyzer_us` / `set mqtt.analyzer_us` still refer to the preset name `analyzer-us`, not “whatever slot 1 default is”.
## Default Configuration
The MQTT bridge comes with the following defaults for fresh installs (unless overridden by the macros above):
- **Origin**: Device name (set automatically from `set name`)
- **IATA**: (blank — must be configured for MeshCore-style topic presets such as Analyzer and TennMesh, unless `MQTT_DEFAULT_IATA` is set at build time)
- **Status Messages**: Enabled
- **Packet Messages**: Enabled
- **Raw Messages**: Disabled
- **RX Packets**: Enabled (uplink received packets)
- **TX Packets**: `advert` by default (uplink this node's own adverts; set to `on` for all TX or `off` to disable)
- **Status Interval**: 5 minutes (300000 ms)
- **Slot 1**: `analyzer-us`
- **Slot 2**: `analyzer-eu`
- **Slots 3-6**: `none` (disabled)
- **WiFi SSID**: (blank — must be configured)
- **WiFi Password**: (blank — optional for open networks)
- **WiFi Power Save**: `none` (no power save)
- **Timezone**: (blank — uses UTC until configured, unless `MQTT_DEFAULT_TIMEZONE` is set at build time)
- **Timezone Offset**: 0 (fallback, no offset, unless `MQTT_DEFAULT_TIMEZONE_OFFSET` is set)
- **Repeat (forwarding)**: On (set `repeat off` for receive-only observers)
## CLI Commands
### MQTT Slot Commands
Each slot (1-6) supports the following commands:
#### Get Commands
- `get mqtt1.preset` - Get slot 1 preset name
- `get mqtt2.preset` - Get slot 2 preset name
- `get mqttN.preset` - Get slot N preset name (N = 1-6)
- `get mqttN.server` - Get custom server hostname for slot N
- `get mqttN.port` - Get custom server port for slot N
- `get mqttN.username` - Get custom username for slot N
- `get mqttN.password` - Get custom password for slot N
- `get mqttN.topic` - Get custom topic template for slot N
- `get mqttN.audience` - Get JWT audience for slot N (custom slots only)
#### Set Commands
- `set mqttN.preset <name>` - Set slot N to a built-in preset. Use any `name` from the [preset table](#slot-based-preset-system) (run `get mqtt.presets` on-device for the full list). Most presets need no further configuration; the exceptions are:
- `meshrank` - requires a per-slot token (`set mqttN.token <token>`)
**Note:** Custom server/port settings only apply when the slot's preset is `custom`. Username/password also apply to built-in presets that use per-slot credentials (e.g. `inwmesh`); other userpass presets (`tennmesh`, `nashmesh`, `ctmesh`) ship fixed credentials in firmware.
#### Example: Configure MeshRank on Slot 3
```bash
set mqtt3.preset meshrank
set mqtt3.token FE1B34242C5938C39225310081FD6718
```
The token is generated on the MeshRank website and is tied to your account. MeshRank only receives packet data (no status or raw messages).
#### Example: Configure MeshMapper on Slot 3
```bash
set mqtt3.preset meshmapper
```
#### Example: Configure Custom Broker on Slot 3
```bash
set mqtt3.preset custom
set mqtt3.server your-broker.example.com
set mqtt3.port 1883
set mqtt3.username your-username
set mqtt3.password your-password
```
#### Example: Custom Broker with JWT Authentication (Ed25519)
For community brokers that support the MeshCore JWT auth protocol (same as the built-in presets), set the `audience` field to enable Ed25519-signed JWT authentication:
```bash
set mqtt3.preset custom
set mqtt3.server wss://my-broker.example.com:443/mqtt
set mqtt3.audience my-broker.example.com
```
When the server is given as a full URL with a scheme (`mqtt://`, `mqtts://`, `ws://`, `wss://`), `set mqttN.port` is optional — an explicit port in the URL is used as-is, and without one the scheme's default port applies.
When `audience` is set, the device will:
- Connect with username `v1_{PUBLIC_KEY}` and an Ed25519-signed JWT as the password
- Automatically renew tokens before expiry (default 24h lifetime)
- Include owner public key and email in the JWT payload (if configured via `set mqtt.owner` / `set mqtt.email`)
To revert a slot back to username/password auth, clear the audience:
```bash
set mqtt3.audience
```
#### Example: Local Development Broker (plain WebSocket, no TLS)
For local development (e.g. a LAN broker without SSL termination), use a full `ws://` URL. Non-TLS transports (`ws://`, `mqtt://`) skip certificate verification entirely:
```bash
set mqtt3.preset custom
set mqtt3.server ws://192.168.1.50:9001/mqtt
set mqtt3.audience my-local-broker
```
The `audience` line is optional — set it if your local broker uses the same JWT auth as the production presets, or use `set mqtt3.username` / `set mqtt3.password` instead.
#### Example: Custom Broker with Custom Topic Template
```bash
set mqtt3.preset custom
set mqtt3.server my-broker.local
set mqtt3.port 1883
set mqtt3.topic mynetwork/{device}/{type}
```
### Custom Topic Templates
When a slot's preset is `custom`, you can define a custom topic template using placeholders:
| `{token}` | Per-slot token from `mqttN.token` | `FE1B3424...` |
| `{type}` | Message type | `status`, `packets`, or `raw` |
If no custom topic is set, custom slots default to: `meshcore/{iata}/{device}/{type}`
**Note:** Topic templates only apply to `custom` preset slots. Built-in presets (analyzer-us, analyzer-eu, meshmapper, meshrank, eastidahomesh, coloradomesh, tennmesh, etc.) always use their hardcoded topic format.
### MQTT Shared Commands
These settings apply across all MQTT slots:
#### Get Commands
- `get mqtt.origin` - Get device origin name
- `get mqtt.iata` - Get IATA code
- `get mqtt.presets` - List available MQTT presets (paginated, comma-separated)
- `get mqtt.presets <start>` - Continue list from index shown in `... next:<idx>`
- `get mqtt.status` - Get MQTT status summary (connection info per slot)

- `get mqtt.tx` - Get TX packet uplinking setting (on/off/advert)
- `get mqtt.interval` - Get status publish interval
- `get mqtt.ntp` - Get effective NTP server hostname
- `get mqtt.ntp.diag` - Probe every configured NTP server for connectivity (does not change the clock; serial console shows each server's reported time, LoRa shows a compact `<server> ok|fail` list)
- `get mqtt.owner` - Get owner public key (serial console only)
- `set mqtt.tx on|off|advert` - Set TX packet uplinking mode:
- `on` - Uplink all transmitted packets
- `advert` - Uplink only this node's own advert packets (self-originated)
- `off` - Disable TX packet uplinking
- `set mqtt.interval <minutes>` - Set status publish interval (1-60 minutes)
- `set mqtt.ntp <hostname>` - Set custom NTP server (validated with immediate sync); `none` reverts to default
- `set mqtt.owner <64-hex-char-public-key>` - Set owner public key
- `set mqtt.email <email>` - Set owner email address
### WiFi Commands
#### Get Commands
- `get wifi.ssid` - Get WiFi SSID
- `get wifi.pwd` - Get WiFi password
- `get wifi.status` - Get WiFi connection status, IP, RSSI, and uptime
- `get wifi.powersave` - Get WiFi power save mode (none/min/max)
#### Set Commands
- `set wifi.ssid <ssid>` - Set WiFi SSID
- `set wifi.pwd <password>` - Set WiFi password
- `set wifi.powersave none|min|max` - Set WiFi power save mode
> **Note:** The value is everything after the first space (spaces in SSID/password are fine). Do not wrap in quotes — they are stored literally. Max length: 31 characters (SSID), 63 (password). For open networks, use `set wifi.pwd ` with nothing after the space.
- `none` - No power saving (best performance, highest power consumption)
- `min` - Minimum power saving (balanced performance and power)
- `max` - Maximum power saving (lowest power consumption, may affect performance)
### Timezone Commands
#### Get Commands
- `get timezone` - Get timezone string (e.g., "America/Los_Angeles")
- `get timezone.offset` - Get timezone offset in hours (-12 to +14)
#### Set Commands
- `set timezone <string>` - Set timezone string (IANA format or abbreviation)
- `set timezone.offset <offset>` - Set timezone offset in hours (-12 to +14)
#### Supported Timezone Formats
- **IANA strings**: `America/Los_Angeles`, `Europe/London`, `Asia/Tokyo`, etc.
Full packet data with RF characteristics and metadata.
### Raw Topic: `meshcore/{IATA}/{DEVICE_PUBLIC_KEY}/raw`
Minimal raw packet data for map integration.
**Note**: `{DEVICE_PUBLIC_KEY}` is the device's public key in hexadecimal format (64 characters).
## JSON Message Formats
### Status Message
```json
{
"status": "online|offline",
"timestamp": "2024-01-01T12:00:00.000000+00:00",
"origin": "Device Name",
"origin_id": "DEVICE_PUBLIC_KEY",

}
}
```
**Notes:**
- Timestamps are always emitted in UTC with an explicit `+00:00` offset.
- The `stats` object is only included when at least one stat value is available; individual fields are omitted when their value is unavailable.
- `packets_sent` / `packets_received` are cumulative totals since boot (flood + direct), sourced from the dispatcher counters.
### Packet Message
```json
{
"origin": "MeshCore-HOWL",
"origin_id": "A1B2C3D4E5F67890...",
"timestamp": "2024-01-01T12:00:00.000000+00:00",
"type": "PACKET",
"direction": "rx|tx",
"time": "12:00:00",

"RSSI": "-65",
"score": "234",
"hash": "A1B2C3D4E5F67890",
"path": ["aa", "bb", "cc"]
}
```
**Notes:**
- All numeric fields (`len`, `packet_type`, `payload_len`, `SNR`, `RSSI`, `score`) are formatted as JSON strings.
- `time` and `date` are always UTC (`HH:MM:SS` and `DD/MM/YYYY`); `timestamp` is UTC with an explicit `+00:00` offset.
- `SNR`, `RSSI`, and `score` are only present for RX packets (received from radio). TX packets omit these fields since the packet originates from this node.
- `score` is the firmware's rebroadcast score for the received packet (the same value used to compute flood-rebroadcast delay), scaled ×1000 to match the integer printed in the serial RX log — e.g. a score of `0.234` is emitted as `"234"` (range `0`–`1000`). It is recomputed at publish time from the packet's SNR and length via the radio's `packetScore()`, so it matches what the firmware used on receive. Omitted when unavailable (e.g. the non-PSRAM reconstruction-less fallback path).
- `path` is only present for direct-route packets that carry path data. It is a JSON array of lowercase hex hop tokens, one element per hop — e.g. `["aa","bb","cc"]` for single-byte hashes, or `["aaaa","bbbb"]` for multi-byte hashes. This matches the `path` representation emitted by [meshcore-packet-capture](https://github.com/agessaman/meshcore-packet-capture).

## Key Features
### Slot-Based Preset System
- Up to 6 concurrent MQTT connections (with PSRAM), 2 without PSRAM
- Built-in presets for many community brokers (see the [preset table](#slot-based-preset-system))
- Custom broker support with username/password auth and custom topic templates
- JWT (Ed25519) for most preset brokers; MeshRank uses token-in-topic; TennMesh uses fixed username/password over plain MQTT
- WSS (WebSocket Secure), direct MQTT over TLS, and plain MQTT (TennMesh)
- Automatic reconnection with exponential backoff per slot
- Circuit breaker pattern with periodic probes for recovery from prolonged outages
- JWT token buffers only allocated for JWT-auth slots (memory efficient)
- Deferred construction: MQTTBridge is heap-allocated in `begin()` to avoid ESP32 static init crashes
### Raw Radio Data Capture
- Captures actual raw radio transmission data (including radio headers)
- Custom primary via `set mqtt.ntp <hostname>`; `set mqtt.ntp none` reverts to default
- `set mqtt.ntp` runs an immediate sync (primary only, so a typo fails fast) when WiFi is connected and the bridge is running
- `get mqtt.ntp` returns the effective primary hostname
- `get mqtt.ntp.diag` probes every configured server (primary + fallbacks) for connectivity and reports each server's time without changing the system clock — a pure diagnostic
- Periodic time updates (every hour) on the effective primary only
- Proper UTC system time handling
### Authentication
The auth mode is fixed per preset (see the [preset table](#slot-based-preset-system)). Three modes are used:
- **JWT Authentication**: Ed25519-signed tokens for brokers that expect JWT (most WSS presets). For `custom` slots, JWT is used when `audience` is set.
- **Username/Password**: Some presets ship fixed credentials embedded in firmware (`tennmesh`, `nashmesh`, `ctmesh` — plain MQTT, no TLS); others (`inwmesh`, `custom`) take per-slot credentials via `mqttN.username` / `mqttN.password`.
- **None**: `meshrank` (account token carried in the topic) and `eastidahomesh` connect without broker auth.
- **Automatic Token Renewal**: Tokens are renewed before expiration
## Migration from Old Configuration
When upgrading from a firmware version that used the old MQTT configuration format (`mqtt.analyzer.us`, `mqtt.analyzer.eu`, `mqtt.server`, `mqtt.port`, `mqtt.username`, `mqtt.password`), the device automatically migrates settings:
- Custom server configured → Slot 3 preset: `custom` with host/port/username/password preserved
- All other settings (origin, IATA, message types, WiFi, timezone) are preserved as-is
The migration happens automatically on first boot after firmware update. No manual intervention is needed.
## First-Time Setup
### Prerequisites
- MeshCore device with observer MQTT firmware flashed
- WiFi network credentials
- Serial console access (115200 baud) or repeater login via companion app
### Step 1: Configure Radio (after fresh flash/full erase)
If this is a fresh flash, radio parameters must be set to match your mesh network:
```
set radio 910.525,62.5,7,5
set tx 22
```
### Step 2: Configure Device Identity
```
set name MyObserver
set mqtt.iata SEA
```
If migrating from an existing device, restore the private key to keep the same identity:
```
set prv.key <your_64_hex_char_private_key>
```
### Step 3: Configure WiFi
Use the rest of the line as the value (spaces allowed; no quotes). See [WiFi Commands](#wifi-commands).
```
set wifi.ssid YourWiFiNetwork
set wifi.pwd YourWiFiPassword
reboot
```
### Step 4: Configure Timezone (optional)
```
set timezone America/New_York
```
Or use an offset as a fallback:
```
set timezone.offset -5
```
### Step 5: (Optional) Disable Repeating
For receive-only observers (e.g., using a PCB antenna or in a location where repeating is not desired):
```
set repeat off
```
### Step 6: Verify Slot Configuration
```
get mqtt1.preset # Should show: analyzer-us
get mqtt2.preset # Should show: analyzer-eu
get mqtt3.preset # Should show: none
```
### Step 7: (Optional) Add Additional Presets
```
set mqtt3.preset meshmapper
```
### Step 8: Verify Connection
```
get bridge.enabled
get mqtt.rx
get mqtt.tx
get mqtt.status
get wifi.status
```
### Troubleshooting
#### Device Won't Connect to WiFi
```
get wifi.ssid
get wifi.pwd
set wifi.powersave none # Try disabling power saving
reboot
```
#### No MQTT Messages Appearing
```
get bridge.enabled
set bridge.enabled on
get mqtt.rx # Should be "on"
set mqtt.rx on
get mqtt.status # Check per-slot connection status
get mqtt1.diag # Last slot error details (TLS/sock/time)
get mqtt2.diag
get mqtt3.diag
get mqtt1.preset # Verify slots are configured
get mqtt.iata # IATA must be set for MeshCore-topic presets (e.g. Analyzer, ColoradoMesh, TennMesh)
```
#### Timezone Issues
```
get timezone
set timezone America/New_York # IANA format
set timezone EST # Abbreviation
set timezone UTC-5 # UTC offset
```
## SNMP Monitoring
Observer nodes include an optional SNMP v2c agent that exposes radio stats, MQTT connectivity, memory usage, and network information to standard monitoring tools. See [MQTT_SNMP.md](MQTT_SNMP.md) for setup and OID reference.
## Fault Alerts
Fault alerts broadcast LoRa group-channel notifications when WiFi or configured MQTT links stay down past configured thresholds, with optional recovery notices and rate limiting to avoid spam.
For configuration, CLI commands, examples, and operational notes, see [ALERTS.md](ALERTS.md).
## Radio Watchdog
The radio watchdog detects a LoRa radio that appears stuck in RX mode but has stopped seeing any activity (valid packets, radio interrupts, or successful TX). When the configured silence interval is exceeded, the firmware idles the radio and restarts receive mode. This helps long-running MQTT observers recover from conditions such as PSRAM starvation that can cause missed radio interrupts without a full reboot.
Activity is tracked from the most recent of: a valid RX, any radio ISR (including CRC errors), or a successful TX. That composite timestamp reduces false recoveries on quiet meshes where legitimate packet gaps can exceed the watchdog interval.
#### Get Commands
- `get radio.watchdog` - Get watchdog interval in minutes (`0` = disabled)
#### Set Commands
- `set radio.watchdog <minutes>` - Set watchdog interval (`0` to disable, or `1-120`)
**Default:** `5` minutes
**Examples:**
```bash
get radio.watchdog
set radio.watchdog 10 # 10-minute silence before recovery
set radio.watchdog 0 # disable watchdog
```
On very quiet meshes where no traffic is expected for long periods, increase the interval or set `0` to disable the watchdog and avoid unnecessary radio recoveries.
## Developer Documentation
For source layout, the seams that isolate the observer feature from upstream MeshCore code, and on-device settings migration across firmware versions, see [MQTT_INTERNALS.md](MQTT_INTERNALS.md).
Developer-facing notes on how the MQTT observer feature is structured in the codebase: source files, the seams that keep it isolated from upstream MeshCore code, and how on-device settings are migrated across firmware versions. For user-facing setup and CLI reference, see [MQTT_IMPLEMENTATION.md](MQTT_IMPLEMENTATION.md).

### Core Implementation
-`src/helpers/bridges/MQTTBridge.h` - MQTT bridge class definition
This document describes the optional SNMP v2c agent that allows network monitoring tools to poll MeshCore observer nodes for health and performance metrics.
## Overview
The SNMP agent exposes radio statistics, MQTT connectivity status, memory usage, and network information via standard SNMP v2c GET/GETNEXT/GETBULK operations. It is designed for use with monitoring tools such as Nagios, Zabbix, LibreNMS, PRTG, or any SNMP-capable system.
- **Protocol**: SNMPv2c (read-only, no SET support)
The SNMP agent runs inside the existing MQTT FreeRTOS task on Core 0 (the WiFi/network core). No additional task is created.
- **Radio stats** are pushed from Core 1 (mesh task) every 2 seconds via `updateRadioStats()`
- **MQTT stats** are updated from Core 0 each MQTT task loop iteration
- **Memory and WiFi stats** are read directly in the SNMP loop on Core 0
The agent starts automatically once WiFi connects and `snmp_enabled = 1` in prefs. It adds approximately 2-3 KB RAM overhead plus per-OID handler storage.
## Build Configuration
SNMP is enabled at compile time with the `WITH_SNMP=1` build flag and included in observer firmware targets:
-`heltec_v3_repeater_observer_mqtt`
-`heltec_v4_repeater_observer_mqtt`
-`Station_G2_repeater_observer_mqtt`
To add SNMP to another observer variant, add the following to its `platformio.ini`:
```ini
build_flags=
...
-D WITH_SNMP=1
build_src_filter=
...
+<helpers/SNMPAgent.cpp>
lib_deps=
...
0neblock/SNMP_Agent
```

## 🔍 What is MeshCore?
MeshCore now supports a range of LoRa devices, allowing for easy flashing without the need to compile firmware manually. Users can flash a pre-built binary using tools like Adafruit ESPTool and interact with the network through a serial console.
MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable.

## Contributing
Please submit PR's using 'dev' as the base branch!
For minor changes just submit your PR and we'll try to review it, but for anything more 'impactful' please open an Issue first and start a discussion. It is better to sound out what it is you want to achieve first, and try to come to a consensus on what the best approach is, especially when it impacts the structure or architecture of this codebase.
Here are some general principles you should try to adhere to:
* Keep it simple. Please, don't think like a high-level lang programmer. Think embedded, and keep code concise, without any unnecessary layers.
* No dynamic memory allocation, except during setup/begin functions.
* Use the same brace and indenting style that's in the core source modules. (A .clang-format is probably going to be added soon, but please do NOT retroactively re-format existing code. This just creates unnecessary diffs that make finding problems harder)
Help us prioritize! Please react with thumbs-up to issues/PRs you care about most. We look at reaction counts when planning work.
### Running unit tests
To run unit tests, run the following command:
```bash
pio test --environment native --verbose

# Restoring accidentally-reverted upstream features
## Background
On 2026-03-20, commit `22eb9b87` — *Revert "Merge remote-tracking branch 'origin/dev' into mqtt-bridge-implementation"* — reverted an entire upstream merge to escape a bad merge state, deleting 860 lines across 66 files. That was not intentional feature removal; it wholesale dropped a batch of upstream progress. When upstream was later re-merged, some collateral came back (MicroNMEA `claim()/release()`, the GAT562 board) but several upstream features were never reconciled and remained missing.
This branch restores them. They are **pure upstream code the fork accidentally dropped**, so restoring re-aligns the fork with upstream and *reduces* the future merge-conflict surface rather than adding to it.
## Phase 1 — duty-cycle enforcement (done on this branch)
Restored the token-bucket duty-cycle enforcement and its cluster:
#warning AsyncElegantOTA library is deprecated, Please consider moving to newer ElegantOTA library which now comes with an Async Mode. Learn More: https://docs.elegantota.pro/async-mode/
#define PRINT_LFS_ERR(_err) do { if (_err) { VERIFY_MESS((long int)_err, dbg_strerr_lfs); } } while(0) // LFS_ERR are of type int, VERIFY_MESS expects long_int
