Share one bounded WiFi outage and recovery schedule across MQTT, automatic NTP, Companion station ownership and WebConfig. Preserve enabled settings and foreground access while allowing normal sleep after confirmed physical shutdown.
Honor failed SDK client stops before handing off WiFi, protect clean teardown and reconfiguration, and retry transient ESP-NOW channel restoration without repeated disconnects. Add production-method, SDK failure and real sleep regressions to CI.
Validation: native MQTT/NTP/clock/reconnect suites; production power and wrapper failure tests; browser, room HTTP, OTA and combined bridge regressions; Full Heltec V4 repeater, room and companion builds with capability, flash and linked-memory checks.
Add opt-in bounded chat history, persist explicit room ACL roles, enforce full-key bans and per-user quotas, and provide versioned information-board reads plus an ESP32 local room page. Preserve stored evidence on faults and withhold room delivery acknowledgments when a Companion cannot retain the message.
Exercise production handlers and filesystem fault recovery, pinned official-app JavaScript, real Chromium interactions, and representative ESP32, nRF52, RP2040 and STM32 builds. Add regression suites and bounded browser-workspace RAM reservations to CI.
Allow unknown blank-password guests only when read-only access is enabled,
disable empty configured credentials, and preserve explicit ACL roles on
reconnect unless a valid admin password selects Admin.
Save room topics through verified, recoverable filesystem transactions. Deliver
topics after older unread posts with independent ACK state and bounded retries,
including clock correction and long-uptime timer handling.
Exercise production handlers and pinned unmodified app JavaScript in CI.
Document topic commands and login policy. Native tests (1829), fault-injection
and compatibility suites, Pico W, V4 Full, G2 Full, and RAK4631 Full/Reduced
build qualification passed. Hardware behavior remains untested for this change.
Reject truncated anonymous reply paths and advert metadata before copying,
while preserving timestamp-only empty-password logins. Limit room posting to
read-write/admin ACL roles, retain inbox frames until the requesting transport
accepts them, and lock raw LittleFS traversal against concurrent writes.
Separate ISR event generations from main-loop radio state. Confirm RX/TX IRQs,
detach concrete wrapper callbacks safely, and discard inconsistent LR2021 FIFO
snapshots before rearming. Preserve bridge RX frames through packet-pool
exhaustion and bound ESP-NOW retries and missing-callback recovery. Screen RTC
register layouts without losing DS1307 startup, and ignore poisoned future
contact timestamps during clock bootstrap.
Keep the nRF52 loop stack at 8 KiB while reducing the OTA listing call chain
from 7,832 to 6,056 static bytes. Retain all target names through lossless Full
Companion compression and the canonical size optimizer. Preserve constrained
STM32 filesystems and bind corrected ESP32 UART/OLED budgets to source size
assertions. Document the separately measured preexisting W12 package limits.
Adapted for this branch from meshcore-dev/MeshCore PRs #3521, #3340, #3362,
#2062, #3503, #3038, #3534, #3544 and #3512.
Validation: 1,829 native tests; sanitized parser, inbox, LittleFS, ACL, clock,
RTC, IRQ/FIFO and bridge fault tests; 332 additional Companion cases; real
RAK4631 Full and both repeater profiles, G2 Full/standard, V3 Full and both
constrained STM32 release recipes. Radio-family compile coverage continues
separately; W12 full/portable package guards remain enforced.
Automatically split longer signed envelopes into two bounded group-data packets, reserve both before queueing, and roll back exact packet copies and retries on admission failure. Collect fragments in either order with a fixed deadline and verify the complete command before durable replay reservation and dispatch.
Raise whole-fleet protocol capacity to 230 bytes, preserve target-specific budgets and radio acknowledgement barriers, and reject rule-token and USB rescue-line truncation. Document existing app input limits and add real-signature, sanitizer, queue failure, timeout, replay, and compact-board regressions.
Enroll a private channel and publisher public key on repeaters and room servers. Local Companion fleet sends sign targeted or whole-fleet commands, with expiry, durable replay protection, and a restricted command allowlist. Preserve exact transmitted-reply barriers for secondary-radio changes, bound validation and replies, and qualify crypto, persistence, transport scope, role permissions, and compact-profile exclusions with regression tests.
Specialize repeater ACL session state, compact recent and flood records, stream Merkle proofs, and release cold OTA buffers safely. Preserve saved formats, stack sizes, table capacities, and OTA source limits. Account for lazy buffers when active and add compatibility, ARM alignment, allocation failure, and queued-response tests.
Validated six representative board/role builds, 1736 native test cases, sanitizer fixtures, and strict documentation. Document the preexisting Wio-E5 Mini flash overflow separately.
Bound ACL replies for encrypted routes, authorize Sensor ACL access using the actual Admin role, and preserve request retries after failed queue admission. Validate stored paths for replies, while keeping Room keep-alives direct-only.
Add both G3 RF-slot Sensor profiles, suppress battery alarms on unavailable measurements, and remove the unsupported Sensor WebConfig capability. Add executable regression coverage and CI checks.
Report the upload address and required network, honor AP switches on an existing uploader, and keep delayed WebConfig cleanup from disabling OTA WiFi. Preserve actionable startup errors and account for OTA in wireless state controls.
Exercise the production OTA lifecycle and stock website console, including power-saving idle sessions, in host regression tests.
The hostname was built once in begin() from the node name, so `set name` left
the node advertising its old name to DHCP until the next reflash. It is now
rebuilt on rename through a new CommonCLICallbacks::onNodeNameChanged() hook,
and begin() shares the same helper.
What this cannot do is rename a live lease. IDF 4.4 states that a hostname
changed after the interface is up "would only be reflected once the interface
restarts/reconnects", and Arduino 2.x's WiFi.setHostname() does not touch a
running netif at all — it writes a static string that the netif reads at
bring-up. Forcing the issue would mean bouncing the link, which costs every
MQTT slot a reconnect; that is not a reasonable price for a rename, so the new
name lands at the next reconnect or boot instead.
Only automatic (Ethernet-preferred) links carry a hostname today, exactly as
before. Giving plain Wi-Fi observers one would change the DHCP identity of the
existing fleet and is a separate decision.
#54 lands first, so the network abstraction is reworked on top of the
per-slot client ownership model instead of alongside it.
Two resolutions are semantic, not textual:
- Link-transition teardown goes through the ownership API. It called
softDisconnect() on every started client, which bypassed client_state and
ignored the typed result. A slot that is still Starting now gets a real
stop: softDisconnect() returns immediately on a client that is not yet
connected, so its attempt would otherwise complete against the old route and
deliver a CONNECTED event indistinguishable from the new one's (F04). On a
medium switch the old route can still be briefly usable, so that is not
hypothetical. A connected client keeps the cheap bounded path, and a
quarantined one is left alone.
- NetworkLink::applyPowerPrefs() adopts WifiPowerSavePolicy. Its local
`2 ? MAX : NONE` mapping would have reintroduced F11 and read the new stored
value 3 (explicit `min`) as none. It also applies the setting when the link
starts already associated, which is the case the bridge used to cover.
The NTP probe from #54 keeps its validation and its one-attempt-per-server
bound, but resolves and gates on the selected link rather than on WiFi, so it
works on an Ethernet-preferred node.
- The room server checked canFlashAfterStop() only when the bridge was
running at OTA time. After a timed-out restart the bridge reads as
stopped while its unacknowledged task may still own TLS/client state,
so an OTA could erase and write flash under it. It now refuses while
the stop is unproven, after first reaping any late ack. The repeater
already gated unconditionally.
- MyMesh::loop() now reaps a late stop acknowledgement whenever it lands,
releasing the withheld queue and buffers, and restarts only when a
resume is pending and the bridge is enabled. Before, a bridge disabled
during StopUnproven kept those resources until re-enabled or rebooted.
pollLateStopAck() is public for this.
- The wrapper's destructor no longer stops an already-stopped client:
destroySlotClients() had just stopped it, so every shutdown logged five
spurious "esp_mqtt_client_stop failed: ESP_FAIL" errors.
Hardware (Heltec V4, 1 s test stop deadline): restart -> StopUnproven ->
`set bridge.enabled off`; the late ack was reaped ("releasing withheld
resources"), status read "not running", and `set bridge.enabled on`
started cleanly without a second release.
setBridgeState(false) returned early when the bridge was already down,
so `set bridge.enabled off` after a timed-out restart left the resume
pending and MQTT restarted against the operator's choice once the task
acknowledged. Disabling now clears the pending resume before that early
return, and the resume also requires bridge_enabled. The StopUnproven
log and `get mqtt.status` no longer say only "reboot to recover", since
a late ack now recovers on its own.
Hardware (Heltec V4, 5 live slots, 1 s test stop deadline): a restart
went StopUnproven, the task acknowledged 27 s later and the bridge
resumed with all slots reconnecting; with `set bridge.enabled off` in
between it stayed stopped until `set bridge.enabled on`.
- A stop that timed out into StopUnproven refused begin(), and only a
later begin() honoured the task's late acknowledgement. Nothing called
it, so restartBridge() (any `set mqtt...` restart) or an aborted OTA left
the observer offline for the rest of the boot. MyMesh now records that a
start was refused and restarts the bridge once stopAcknowledgedLate()
reports the ack. The OTA-abort alert no longer claims "bridge resumed"
when the restart was refused.
- refreshNTP() now runs the validated probe with one attempt per server.
With two attempts and a 1 s pause it blocked the MQTT task ~18 s every
hour on networks that drop UDP/123, where the old async SNTP cost
nothing. Loop comment and docs updated to match.
startLanMode() took the caller's IP, read before the route lock. A
Wi-Fi/Ethernet switch in between left WebConfig locked to the new link
while advertising the old link's address. It now reads the selected
link's address after lockSwitching(), as startOTAUpdate() already does.
The upstream `password` command saves /prefs.json without reporting the
result, and WebConfig overwrites its reply with "OK". If that write failed
while the later /mqtt.json write succeeded, wifi.setup_complete was set and
the factory password came back after reboot with first-run setup
suppressed. onInitialSetupComplete() now re-saves /prefs.json and records
completion only when it succeeds; otherwise the batch fails, setup stays
open, and no reboot is queued.
- Guard the boot-time link bootstrap to observer ESP32 builds. It ran
unconditionally in MyMesh::begin(), breaking every non-observer
repeater/room server build (ESP32 and nRF52).
- Rename NetworkInterface -> NetworkLink (class, accessor, files).
Arduino-ESP32 3.x ships its own NetworkInterface class and header,
which broke the ESP32-C6 builds. Drop WiFi.setAutoConnect(), a no-op
on 2.x and removed in 3.x.
- Refresh stored Wi-Fi credentials every bridge tick so the STA
reconnect loop picks up `set wifi.ssid` / `set wifi.pwd` without a
reboot, as the bridge did before the link moved out of it. Skip
reconnects while the SSID is empty.
- Restore the "WiFi connected: <ip>" / "WiFi disconnected: reason N"
debug lines the bridge used to print.
- Alert on Ethernet only once it has held a lease this boot or when no
Wi-Fi is configured; Wi-Fi-only installs of an Ethernet-preferred
image keep Wi-Fi alerts instead of reporting "Ethernet down".
- Record wifi.setup_complete only for Ethernet LAN onboarding, so
Wi-Fi builds keep the SSID-based first-boot portal rule.
- Use seq_cst for the route-switch lock/mutation flag handshake.
- Docs: SNMP RSSI sentinel is -127; describe link-return vs medium-switch
reconnect behavior accurately; note runtime credential pickup.
- Test: unknown keys inside a known /mqtt.json group are ignored, which
keeps wifi.setup_complete downgrade-safe.
