companion_radio has its own NodePrefs without radio_fem_rxgain (matching
upstream, which doesn't wire companion either), so the startup call added in
e905451d broke every companion build:
MyMesh.cpp:973: error: 'struct NodePrefs' has no member named 'radio_fem_rxgain'
It went unnoticed behind the pre-existing companion build failures.
Also port upstream's FEM LNA overrides for heltec_t096 and heltec_tracker_v2
verbatim (board overrides + isLNAEnabled/const getters), so all three boards
upstream wires now match instead of reporting unsupported. Both variant files
compile; those targets still fail overall on the pre-existing non-observer
MQTT-source build-config issue (unchanged with this work stashed).
Match upstream pin map (KCT8103L CSD/CTX, I2C 6/17, LORA_TX_POWER=9) and restore meshcore LoRaFEMControl.cpp and HeltecTrackerV2Board.cpp. Run ESP32 at 240MHz for MQTT/WiFi bridge headroom. Sensor env drops fork-only ENV_PIN overrides to match upstream.
Made-with: Cursor
Upstream adds LoRaFEMControl for a KCT8103L pinout; this variant uses GC1109 (P_LORA_PA_*). Reintroduce the class with the same API and wire HeltecTrackerV2Board through it so FEM logic matches platformio.ini.
Made-with: Cursor
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.
- Updated the begin() method to handle deep sleep and cold boot scenarios for GC1109 FEM pins.
- Improved pin configuration logic for power management and transmission control.
- Enhanced comments for clarity on pin roles and behavior during sleep and wake cycles.
- Adjusted platformio.ini files to reflect updated pin definitions and usage notes.
