Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
- GxEPDDisplay now uses the same single misc-fixed 6x9 font as the OLED
driver (Lemon retired there too), with baseline math updated for the
new ascent.
- Clock Tools' Alarm screen: Repeat and Armed now respond to LEFT/RIGHT
like every other multi-value/toggle field in Settings, not Enter-only;
Hour/Minute merged into one Time row edited with a hand-rolled HH:MM
digit cursor (like the Timer's), replacing the two-row DigitEditor
popups; Repeat's "Off" label now matches the codebase-wide ON/OFF
casing.
- Top status bar: battery icon now shares the same box height as the
other status icons (Bluetooth/mute/etc.) instead of standing 2px
taller, and its charge nub is properly vertically centred instead of
drifting off-centre at non-multiple-of-4 box heights.
- Small settings-gear icon glyph tweak; wio-tracker-l1 screenshot build
variant now enables DUAL_SERIAL.

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 per-read VBAT_ENABLE gating from 4d46abb2 (energy optimizations)
powered the battery voltage divider HIGH for only 10ms before each ADC
read, then LOW. 10ms is too short for the high-impedance divider node
to settle before the nRF52 SAADC samples it, so readings came out high
and inconsistent (e.g. 4.6-5.0V on a LiPo that maxes ~4.2V).
Hold VBAT_ENABLE HIGH continuously again (as before 4d46abb2) so the
node is always settled at sample time, and drop the toggle + delay(10)
from getBattMilliVolts(). Standby cost is ~2uA on the 2x1M divider,
negligible next to the device's mA-level draw.
The CPU-sleep and LED-off energy optimizations from 4d46abb2 are left
untouched — those are the real savings; only the VBAT gating is reverted.
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.
E-ink panel refreshes block the main loop for 500ms-3.6s (GxEPD2's
display.display() waits on the BUSY pin), and MomentaryButton::check()
only ever samples the live pin level once per loop iteration. A full
press+release that lands entirely inside a refresh is never sampled,
not just delayed - users on WioTracker L1 Eink were losing taps.
Add an opt-in ISR path (BUTTON_USE_INTERRUPTS) that latches each edge
with its own timestamp into a small ring buffer from attachInterrupt(),
independent of what the main loop is doing. check() replays buffered
edges through the existing transition/multi-click logic afterwards, so
click-duration and multi-click-window math still uses the edge's actual
capture time rather than "now".
Scoped to wio-tracker-l1-eink only for now: it's the one board this was
reported against and the only GxEPDDisplay-class variant that currently
builds clean on main. OLED boards refresh in ~20-30ms so polling already
catches every press; analog-button boards (rak4631/rak3401) can't use
attachInterrupt(CHANGE) at all.
