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.
Previously load() returned true unconditionally on file-open success,
masking truncated or corrupt /regions2 files. Additionally, the first
field of each entry record (r->id) used the same success-chaining
pattern as subsequent fields, so a clean EOF at a record boundary set
success=false and would have been indistinguishable from real
corruption once the return value was fixed.
The r->id read is now split out: n==0 is a clean EOF (break, success
retains its prior value from the header read), n!=sizeof(r->id) is a
partial read or corruption (break, success=false). load() now returns
success instead of an unconditional true, so its return value reflects
the actual parse outcome.
Companion fix to #2372, which fixed the same return-true hardcoding
in save(). (#1891 originally reported this on load() but was closed
when #2372 landed — that PR only touched save(); this addresses the
load() side.)
Adds a small allocation for groupdata packets for the Meshcore firmware for the StreamSensor product. It was previously a LoRaWAN platform, and we've moved to Meshcore.
GPS support was implemented incorrectly for the ThinkNode M3. The reset
pin was being driven when it should be left floating for this unit. The
enable pin also wasn't being picked up by `MicroNMEALocationProvider`
because of a mismatch in constant naming conventions. I did a general
cleanup of the GPS and ThinkNode M3 bring-up code so that constant names
line up and "*_ACTIVE" constants are used consistently vs hardcoding
`HIGH`/`LOW`. After making these changes, serial data immediately starts
streaming in from the NMEA on boot and GPS detection just works.
LED handling was also not quite right for the ThinkNode M3. The LoRa TX
LED was being driven high to turn it on when it should actually be
driven low. I changed the code to use the `LED_STATE_ON` constant and
also added a little code to the shutdown path to properly make sure that
all LEDs are turned off.
Tested and confirmed working on real hardware.
Resolves both #1864 and #2879.
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.
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.
- 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
The M6's L76K GPS streams NMEA at 9600 baud on its own, but the firmware
reported no GPS. Root cause: pin 29 (PIN_GPS_RESET / the module's REINIT
line) was driven HIGH, which holds the L76K silent so it never emits any
sentences and detection fails.
variant.cpp drove pin 29 HIGH at boot, and because PIN_GPS_RESET was
defined, MicroNMEALocationProvider also drove it HIGH in begin(). Bench
testing on a sealed M6 (passive NMEA capture, no logic analyzer) confirmed:
pin 29 driven HIGH = 0 bytes; pin 29 floating = full NMEA stream.
Define GPS_RESET (-1) so the location provider never touches pin 29, and
stop driving it in initVariant. This matches the Meshtastic M6 variant,
which leaves the same pin as a floating input.
