Port the observer doc cleanup from observer-firmware (4beb5472) onto dev,
keeping dev-specific content intact.
- move internal mechanics into MQTT_INTERNALS.md: deferred construction,
runtime slot memory, backoff/circuit breaker, message building, command
namespacing, and the legacy prefs key mapping
- drop the duplicated First-Time Setup, Command Architecture, and SNMP
Monitoring sections, folding their unique steps into Quick Start
- condense the partition/NVS prose and merge the five custom-broker
examples into one Custom Brokers section
- promote the preset list to a top-level Broker Presets section with an
Extra setup column, and document the presets the table was missing:
meshcore-fi, corecomms, mesh-chaun14, wcmesh, and meshtexas
- fix the coloradomesh port (443, not 1883)
- point flasher and changelog links at observer.gessaman.com
- restore the nbr: status field, which the code still emits, and correct
the neighbors topic to QoS 0 retained per allow_retain
Dev-specific content is preserved as-is: per-slot packet filters, the Web
Configuration Portal, local testing without hardware, MeshRank's raw
exclusion, and neighbors default_scope.
First upstream merge since the 2026-06-06 base (191 upstream commits). 14 files
conflicted; resolutions below.
Fleet-critical check (Constraint 1): upstream reordered NodePrefs members
(rx_boosted_gain / path_hash_mode moved to the struct tail) but did NOT change
/com_prefs. Persistence is written field-by-field at explicit offsets, so member
order is in-memory only. Verified the fork's writeCommonPrefsImage() is
byte-identical to upstream's inline writer at every offset (79 pad, 121, 122,
290-294). No migration needed.
Resolutions:
- CommonCLI.h: kept the fork's NodePrefs (superset) and adopted upstream's
setRxBoostedGain(bool)->bool signature change, which CommonCLI.cpp now uses to
report unsupported. Corrected a stale comment claiming rx_boosted_gain lives at
offset 79 (it is a pad; the field is at 290).
- CommonCLI.cpp: kept the fork's legacy /com_prefs migration and the extracted
writeCommonPrefsImage() call.
- UITask.cpp: three-way merge - upstream's drawTextCentered + powering-off
screen, plus the fork's WITH_WEBCONFIG portal/reboot screens.
- ESP32Board.cpp, MeshCore.h, platformio.ini: kept both sides (fork OTA additions
alongside upstream powerOff/enterDeepSleep and Packet.cpp).
- MicroNMEALocationProvider.h: took upstream's claim/release and added the
_claims member they depend on.
- MyMesh.cpp/.h (repeater + room server): kept the fork's superset defaults.
- Removed duplicate declarations auto-merge produced: RadioLibWrapper::_cad_enabled
and MyMesh::getCADEnabled().
Verification: native suite 15/15 (incl. upstream's new test_mesh_tables), both
MQTT smoke builds green, ArduinoJson pin check passes. Hardware validation next.
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.
Added small section under RAK compatibility for info on how to convert hex to uf2, with link to Microsoft GitHub uf2conv python script. Cleaned up how links display in that section.
