Roll back failed password and advert changes, propagate identity-store results, and report unsaved common and observer settings. Correct observer filter persistence and KISS OTA capability claims. Add fault-injection and packaging regressions.
Distinguish OTA read failures from missing blocks and select unique raw-flash checkpoints by MID and target. Keep deferred CLI requests and replies bound to immutable command identity and full authenticated keys.
Gate radio mutations on their exact reply delivery, recover coding-rate restoration, and roll back failed Companion preference writes. Preserve accepted low duty cycles across reboot.
Retain partial network writes, cancel displaced client operations, and reject malformed or stalled framed input. Add regression and CI coverage, and size-optimize the RAK4631 Ethernet build without dropping features.
Apply due radio2 settings by requested start time and expire every old temporary
window before starting its successor. Anchor temporary deadlines to command
acceptance so idle time before a command cannot shorten the new lease.
Keep failed radio2 saves in their original order and retry without rewriting
their scheduled timestamps. Give repeater persistence its own backoff and cache
the next actionable deadline, preventing repeated writes while allowing
temporary windows to start and expire on time.
Exercise all 24 slot insertion orders with punctual and delayed servicing, plus
adjacent windows, storage failures, command-time anchoring, and timer rollover.
Persist Companion TX preferences per contact and channel. Default repeater,
room, and sensor replies to both active TX profiles, with a reply-only force
option for an RX-only secondary profile. Track both reply copies before a
temporary-radio handoff and account for OTA copies under queue backpressure.
Add bridge/crossover filter modes and the third built-in wardriving filter,
plus compact filter CLI syntax, documentation, and CI coverage.
Fix quoted target names being interpreted as slot/key selectors, partial
recovery of invalid saved reply settings, filter suspension during tempradio2,
and unnecessary packet allocation while OTA traffic is throttled.
Validation: 1,477 native tests, 52 Python integration tests, 29 filter UI tests,
and five firmware builds covering ESP32, nRF52, and STM32 passed.
Implement radio2, tempradio2, radioat2 and tempradioat2 across Mesh roles,
with RX-only/RX+TX operation, optional preambles and persistent cross-TX
policy. Keep temporary OTA traffic on its profile by default and maintain
independent retry ownership and backoff for each profile.
Use slow-first receive scanning with 4.8-symbol visits and automatic
preambles rounded up in steps of eight. Preserve pending RX, restore power
saving on exit, and discard work bound to changed or expired profiles.
Restore the infrastructure path.hash.mode setter and report unsupported
extra.sf settings consistently. Add CLI, scheduling, scan and retry tests,
setup documentation, and the V4/XIAO hardware validation results.
Validation: 1,422 native tests, eight KISS tests, 63 final focused profile
tests, 18 checks from the staged source, sanitizer-enabled OTA transfers,
and builds for V4 Mesh roles, Full XIAO Companion and nRF52 T1000-E.
Hardware checks cover reception, cross-TX policy, expiry, reboot and OTA
discovery while receiving main-channel adverts.
Use RX-only radio recovery and feed the repeater reboot watchdog after MeshCore parsing. Default to 24 hours, apply temporary watchdog and advert intervals in RAM, and report temporary durations as days, hours, and minutes. Add regression coverage and an ESP-NOW bridge setup guide.
Integrate ExpressLRS TX module support and its stacked ESP32 heap changes.
Use the approved Linkflow calibration (17-30 dBm), preserve the PA drive
and output path after radio recovery, and keep LoRa OTA enabled.
Preserve stored ACLs and filters on allocation failure, release owned
client/filter buffers, service heap OTA contexts on Companions, release
self-serving workspaces after TempRadio, and reset staged-resume state
when a context is released. Keep manual staging and active operations
alive. Account for all moved allocations in the runtime RAM gate.
Validation: 1,393 native cases; radio-power, heap-context, ACL persistence,
shared-queue transfer, display/inbox, radio receive, and memory regressions.
Firmware builds passed for Linkflow, Heltec V2 Companion, T-Beam MQTT
repeater, Heltec V4 R8 MQTT repeater, RAK4631 repeater, and Indicator Full.
Physical verification awaits access to the currently offline lab Pi.
Classic ESP32 links into a dram0_0_seg of only 124,580 bytes: memory.ld
carves the BT controller's 0xdb5c (56,156) reservation off the 0x2c200
window before the application gets any. Three large objects dominated what
was left, and Tbeam_SX1262_repeater_observer_mqtt overran the build's 8 KiB
static reserve by 4,744 bytes.
Heap-allocate them instead, each with a defined behaviour when the
allocation fails:
- OtaContext: generalize the Companion's borrowed-storage path behind
OTA_DYNAMIC_CONTEXT and add OTA_HEAP_CONTEXT, which allocates the context
on first use and frees it once no transfer, apply or folder link needs it.
A repeater is idle nearly all the time, so the workspace is usually absent.
Exhaustion is reported to the caller and the operation declines.
- ClientACL: the client table becomes a pointer with a live capacity;
capacity 0 refuses new clients rather than writing through a null table.
- MyMesh flood packet filters: likewise, with flood_packet_filter_slots as
the live bound for every rule loop. At capacity 0 the node forwards
unfiltered, and both save paths refuse to write so a stored ruleset is
never replaced by an empty file.
Also override the Arduino SDK's weak btInUse() in simple_repeater so
initArduino() releases the BT controller memory to the heap. That grows the
runtime heap these tables now come from; it cannot recover the same
reservation from the linker's static window.
Static DRAM, classic ESP32:
Heltec_v2_repeater 108,332 -> 70,732
Tbeam_SX1262_repeater_observer_mqtt 121,132 -> 83,532 (was failing)
Add durable TempRadio, ACL, clock, bridge, GPS/I2C, USB logging, and Indicator recovery safeguards together with expanded automation, build/profile contracts, release metadata, and the hardware validation ledger.
Add selectable shared ESP-NOW channels, raw/wrapped bridge compatibility, and bounded fragmentation for maximum-size packets.\n\nGive ESP32 Full profiles WiFi coexistence, stabilize WebConfig and USB terminal lifecycles, and keep disabled bridges stopped during observer updates.\n\nUpdate generated UI, firmware selection, documentation, and regression coverage.
Add the framed BLE mOTA transport and companion control path, complete the full-profile build and runtime fixes, and document and test the OTA workflow.
Expose the Full Companion terminal over TCP and add an authenticated, replay-resistant host command service with documented CPU temperature, reboot, and allowlisted program examples.\n\nImprove LoRa OTA diagnostics and persistent CLI handling, reduce clock correction drift to ten minutes, and make mOTA stream flush behavior an explicit transport policy with regression coverage.
Picks up upstream MeshCore 1.17.0 and the dev commits that followed it.
Notable upstream content:
- 1.17.0 version/build-date bump in the example MyMesh headers.
- anon_req hardening: reply_path_len is now uint8_t with an isValidPathLen()
bounds check and a 0xFF sentinel; reply_path_hash_size is gone.
- LR2021 support (Meshnology W12, Seeed MeshTracker X1) incl. side detectors,
multi-SF and the new `extra.sf` get/set CLI.
- CustomLFS 0.2.2 -> 0.2.3 (GD25Q64C support).
- kiss_modem envs for several nRF52 variants; ThinkNode M6 GPS/flash fixes.
Conflicts resolved:
- platformio.ini: took upstream's CustomLFS 0.2.3, kept our lib_ignore for
the vendored PsychicMqttClient.
- CommonCLI.h: kept both upstream's USE_LR2021 configSideDetectors() hook and
our fault-alert callbacks.
NodePrefs gains upstream's extra_sf[4], which is not registered with
ConfigSerializer, so /prefs.json layout is unchanged.
Verified: 275/275 native host tests pass; Heltec_v3_repeater_observer_mqtt,
Heltec_v3_repeater and heltec_v4_repeater_observer_mqtt all build.
Improve companion BLE delivery and idempotent remote CLI retries, make FPF7 persistence atomic with FPF6 migration, verify staged OTA data on resume, and clarify filter policy wildcard and BlackHole semantics.
