Without ROOM_PASSWORD the guest password defaults to empty, and a client
sending a blank password is granted read+write access (can post). Every
other board's room_server env sets ROOM_PASSWORD; the ThinkNode M6 and M1
were the only two shipping an open room. Default them to "hello" to match
the rest of the tree; operators can still change it at runtime with
'set guest.password'.
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.
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 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.
