Drive WB_IO2 (slot power switch) HIGH via early constructor before the
Arduino framework initializes. Without this, the board brownouts on
POE-only power because the slot MOSFET isn't enabled early enough for
the RAK13800 POE module to deliver power to the baseboard.
Also remove the W5100S hardware reset pulse from Ethernet init — the
chip comes out of power-on reset cleanly, and toggling reset kills
the PHY link which breaks POE power delivery.
Resolve conflicts: keep both Ethernet CLI and SenseCAP power-off
button code in repeater, keep both Ethernet docs and power management
CLI docs.

Enable GPS time synchronization across all variants by passing
&rtc_clock to MicroNMEALocationProvider. When GPS gets a valid
fix, the RTC clock is now updated automatically every 30 minutes.
Updated 16 variants: rak4631, lilygo_tbeam_SX1262, rak_wismesh_tag,
lilygo_tbeam_supreme_SX1262, thinknode_m3, heltec_v4, thinknode_m1,
lilygo_tbeam_SX1276, meshadventurer, nano_g2_ultra, heltec_v3,
promicro, xiao_c3, heltec_tracker_v2, keepteen_lt1, heltec_mesh_solar.
Pin mapping verified against HTIT-Tracker V0.5 schematic:
- GPIO35 (GPS_EN): N-ch MOSFET drives P-ch high-side switch, active HIGH
- GPIO36 (GPS_RST): hardware reset, active LOW
- GPIO33/34: UART TX/RX
Delegates power management to MicroNMEALocationProvider begin()/stop()
which independently controls GPS power via GPS_EN and shares VEXT with
the display through RefCountedDigitalPin.
The RAK13302 1W module uses a Skyworks SKY66122-11 front-end module with
three digital control pins (CSD, CTX, CPS) that must be actively driven
by the host MCU. The previous code only managed CTX (GPIO 31) — toggling
it for TX/RX — but never initialized CSD (GPIO 24) or CPS (GPIO 21),
leaving them floating with no pull-up/pull-down resistors on the PCB.
With floating CSD and CPS, the SKY66122 was in an undefined operating
mode:
- The 30 dB TX PA may not have been reliably engaging
- The 16 dB RX LNA was never reliably active, degrading receive
sensitivity
The GC1109 FEM needs its VFEM_Ctrl pin held HIGH during deep sleep
to keep the LNA active, enabling proper RX sensitivity for
wake-on-packet. Without this, the LNA is unpowered during sleep
and RX wake sensitivity is degraded by ~17dB.
Release RTC holds in begin() after configuring GPIO registers
(not before) to ensure glitch-free pin transitions on wake.
Trade-off: ~6.5mA additional sleep current for significantly
improved wake-on-packet range.
This change addresses two issues. The first is that the
LilyGo_TLora_V2_1_1_6_terminal_chat build would try to compile
simple_repeater/MyMesh.cpp. All other examples of terminal chat
targets are instead building simple_secure_chat/main.cpp . This
change would align this build to the rest of the builds.
The second issue, found during the course of investigating the
first, stems from simple_repeater/MyMesh.cpp using the
MAX_NEIGHBOURS #define to control whether the neighbor list is kept.
Repeaters that keep this list must define this value, and if the
value is not defined, then all neighbor-related functionality is
compiled out. However, the code that replies to
REQ_TYPE_GET_NEIGHBOURS did not properly check for this #define,
and thus any target that compiles simple_repeater/MyMesh.cpp
without defining MAX_NEIGHBOURS would get an undefined variable
compilation error.
As a practical matter though, there are no targets that compile
simple_repeater/MyMesh.cpp AND do not define MAX_NEIGHBOURS,
except this build due to the first issue. As a result, the
second issue is addressed only as a matter of completeness. The
expected behavior with this change is that such a repeater would
send a valid reply indicating zero known neighbors.
Sensors connected via the Grove I2C connector (D18/D17) were not detected
because the firmware scanned the OLED I2C bus (Wire, D14/D15) by default.
Adding ENV_PIN_SDA/SCL flags directs EnvironmentSensorManager to use Wire1,
matching the physical Grove connector pinout.
