A neighbour heard before the clock is set carries the firmware's unset-clock
default (1715770351, 15 May 2024). Subtracting that from an NTP-synced clock
published ages of ~806 days for neighbours that had just answered a live scope
query, and a backwards clock step reported 0, i.e. "heard just now".
- finishNeighborDiscover() reports the age as unknown ("heard_secs_ago": null)
when the stored stamp and the current clock come from different epochs, or
when the clock has stepped backwards
- handleNeighborDiscoverResponse() re-stamps heard_timestamp on a zero-hop scope
reply, in both the snapshot and the live table, so entries heal once per
discovery cycle instead of waiting for the neighbour's next advert
- publish ordering places usable ages ahead of unknown ones so a poisoned stamp
cannot displace fresh entries when the JSON buffer truncates
- document the null case, and the always-present total_neighbors /
queried_neighbors / truncated fields the payload sample omitted
- add UPSTREAM_BUGS.md, tracking the monotonic-uptime fix to propose upstream
plus the unclamped subtraction in the companion and CLI readouts
Containment only: upstream still stamps neighbours from the wall clock at
packet-reception time, which on a cold boot always precedes NTP.
Absorbs 106 upstream commits. Seven files conflicted; the substantive one
was upstream's new JSON ConfigSerializer (PR #2982), which replaces the
binary /com_prefs layout with /prefs.json and makes NodePrefs a
ConfigSerializer subclass.
Prefs migration
- Adopt upstream's ConfigSerializer. writeCommonPrefsImage() and its
documented offsets (0-294) are deleted, along with the now-unreachable
saveCommonPrefsImageAtomically()/CommonPrefsFileStore atomic rename path.
- Load order is /prefs.json, then /com_prefs, then /node_prefs. Upstream
dropped the /node_prefs fallback; it is restored here so devices that
never advanced past that filename keep their config.
- Legacy files are never removed, so migration cannot destroy its own
source and a deferred or failed save simply retries next boot.
- /com_prefs is treated as a format migration only, not an "upgrade", so
it does not trip the bridge.source tx->rx flip on existing nodes.
- The MQTTPrefsAtomicStore legacy gate is retained: the observer tail
recovered from an old-format file still commits to /mqtt_prefs before
/prefs.json is written.
- MQTTPrefs and /mqtt_prefs are untouched; savePrefs keeps its save_mqtt
parameter and now returns upstream's bool.
Fixes to upstream code
- RadioPrefs::structure() bound both "rxgain" and "fem_rxgain" to
rx_boosted_gain, so radio_fem_rxgain was never persisted. Bound to the
correct field.
- discovery_mod_timestamp was dropped from structure(); it gates
'since'-filtered DISCOVER replies and is set on every config change, so
losing it would silently stop discovery responses after a reboot. Added
as "disc_mod".
Merge artifacts repaired
- Restored bblanchon/ArduinoJson to the native test env; a clean but wrong
auto-merge at the lib_deps block boundary dropped it and broke all 19
host test suites.
- Migrated the fork's WebConfig UITask screens off the removed
DisplayDriver::Color enum to upstream's UIColor element types.
- Removed duplicate getCADEnabled() definitions in companion MyMesh.cpp
and simple_sensor SensorMesh.cpp that both sides had added.
- Dropped memset(&_prefs, 0, ...) in the four example meshes; NodePrefs now
has a vtable. guard gains an initializer that memset used to provide.
Other resolutions
- simple_room_server keeps both the fork's discover.* commands and
upstream's new room.post.
- docs/payloads.md taken from upstream, undoing content earlier merges had
reverted (Control data section, split login tables).
Verified: 273/273 host tests pass across native and native_kiss_modem;
Heltec v3 repeater, repeater_observer_mqtt, room_server_observer_mqtt,
sensor, and companion_radio_ble all build clean.
Enhance the neighbor discovery JSON structure by introducing a
default_scope field, which indicates the region name this node
floods to by default. This change improves clarity in the
neighbor discovery process and aligns with the unscoped flood
behavior when no default region is set. Updates include
modifications to the MyMesh class and related message building
functions to accommodate the new field.
Add support for named packet types in per-slot filters, allowing users
to specify packet types using descriptive names alongside numeric values.
This improves usability and clarity in configuring MQTT slot filters.
Updates include modifications to the parsing logic, WebConfig interface,
and related documentation to reflect the new naming conventions.
Introduce new methods to manage neighbor discovery JSON budget and
entries in MyMesh. This includes tracking the number of queried and
published neighbors, measuring JSON sizes, and handling truncation
when the buffer limit is reached. These improvements optimize the
neighbor discovery process and ensure efficient JSON message
construction for MQTT communications.
Add functionality to manage neighbor discovery requests in MyMesh.
This includes handling the status of requests, updating the state
upon transmission success or failure, and implementing a timeout
mechanism for neighbor discovery queries. The changes improve the
efficiency and reliability of neighbor discovery operations in
MQTT-enabled environments.
The room server never supported RX boosted gain, while the repeater
does. Three consequences on SX1262/SX1268 boards:
- boosted gain was never applied to the radio at boot, so a room server
ran in power-saving RX mode while an identical repeater ran boosted -
a real receive-sensitivity difference with nothing pointing at it
- _prefs.rx_boosted_gain was never initialised (the prefs are memset to
0 before defaults are set), so it defaulted to off
- 'set radio.rxgain on' replied "Error: unsupported" but CommonCLI had
already written the value to prefs and saved them, so a stale setting
survived reboot and was never applied
Mirror the repeater's implementation: initialise the pref default under
the same USE_SX1262/USE_SX1268 and SX126X_RX_BOOSTED_GAIN guards, apply
it during radio init, and override setRxBoostedGain() so the CLI reports
success and takes effect.
Built Heltec_v3_room_server (SX1262) and LilyGo_T3S3_sx1276_room_server
(guards compile out cleanly).
Implement SNMP functionality in MyMesh to provide radio diagnostics
and statistics updates. This includes a new method for formatting
radio diagnostic replies and periodic updates to the SNMP agent
with radio stats, enhancing monitoring capabilities for users
with SNMP enabled.
Add functionality to schedule deferred OTA updates in the MyMesh class.
This includes a new member variable to track the update time and a method
to initiate the update process, allowing for a smoother OTA experience
by managing timing and state transitions effectively.
Cherry-picked from observer-firmware (76f44d7d). Resolved a conflict in
loop() where the WITH_WEBCONFIG block occupies the same anchor and shares
an identical closing tail; both blocks retained.
