From f224a325e68164e39c9c8169b7c47b84bf9b5e86 Mon Sep 17 00:00:00 2001 From: jirogit Date: Thu, 2 Apr 2026 21:18:34 -0700 Subject: [PATCH 01/25] fix: enable radio.rxgain CLI command for LR1110 (T1000-E) USE_LR1110 was missing from the preprocessor guard in CommonCLI.cpp, causing both get and set to fail silently on T1000-E: - get radio.rxgain returned the full radio config string (fell through to the memcmp("radio", 5) branch) - set radio.rxgain returned "unknown config" (no branch matched) Fix: add -D USE_LR1110 to variants/t1000-e/platformio.ini and include USE_LR1110 in the #if guard on both get and set branches. CustomLR1110Wrapper already implements setRxBoostedGainMode() and getRxBoostedGainMode() via the RadioLibWrapper virtual interface, so no radio-layer changes are required. Tested on T1000-E: get/set/persist all confirmed working. --- src/helpers/CommonCLI.cpp | 4 ++-- variants/t1000-e/platformio.ini | 1 + 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/src/helpers/CommonCLI.cpp b/src/helpers/CommonCLI.cpp index b71afc72..2dba656d 100644 --- a/src/helpers/CommonCLI.cpp +++ b/src/helpers/CommonCLI.cpp @@ -547,7 +547,7 @@ void CommonCLI::handleSetCmd(uint32_t sender_timestamp, char* command, char* rep _prefs->disable_fwd = memcmp(&config[7], "off", 3) == 0; savePrefs(); strcpy(reply, _prefs->disable_fwd ?

I will close my other PRs related to this and link back to this one. *Background on change:* This change replaces the Adafruit BME680 driver on RAK4631 with the Bosch BSEC library. Other boards continue to use the existing Adafruit path via ENV_INCLUDE_BME680. This makes the IAQ portion of the sensor functional, and more accurate. It also contains the math and/or CayenneLPP fixes from my other PRs. The Bosch code also appears to handle calibrating sensor aging as well, whereas the Adafruit code is just looking at blind values that can drift with time. Pretty cool to see this shooting out useful data! RAK4631 platform.io is set to override to ENV_INCLUDE_BME680_BSEC while leaving the Adafruit code for other node types. (If this becomes applicable for other node types in future, awesome! I just don't have hardware to test against.) Using the BSEC library introduces IAQ sensor calibration, and saves the calibration state periodically so it does not have to calibrate again later. At startup the IAQ sensor takes 30 minutes to heat and to hit a baseline, then starts calibrating. Once calibrated, it will save those settings and will only write settings again if calibration falls back and restores back to state 3. This fix also has the gas resistance math fix that was in [pull 2146](https://github.com/meshcore-dev/MeshCore/pull/2146) so the adafruit path also can at least show accurate values instead of looping negative. Also includes the fix from [pull 2149](https://github.com/meshcore-dev/MeshCore/pull/2149) so the pressure output isn't truncated to 1hPa steps. *Fixes/Changes:* - Add bsec_config_iaq[] with the 3.3V/3s-LP/28d calibration profile - BSEC init applies setConfig() for voltage-correct heater targeting - IAQ, heat-compensated temperature/humidity, pressure, and altitude reported over CayenneLPP - IAQ accuracy reported as analog input over CayenneLPP (0,1,2,3) - Calibration state persisted to /bsec_state.bin on nRF52 internal flash; written only when iaqAccuracy improves to >= 2, should keep write frequency well within flash endurance over device lifetime - Fix non-BSEC query_bme680: float pressure division, addGenericSensor for gas resistance (was addAnalogInput, overflows at > 327 Ohm) - loop() correctly gated for both GPS and BSEC-only builds - Add fix_bsec_lib.py extra_script to resolve nRF52840 hard-float ABI mismatch in Bosch's PlatformIO packaging, silly Bosch One general note outside of this code change: I noticed while BME680 _functions_ in companion nodes, since companion nodes run Bluetooth, BLE preempts the CPU, and can do so mid-I2C-transaction. This can cause the BME680 to see an anomaly and drop calibration and start a recalibrate. This is behavior that will exist (and has existed) regardless of using the Adafruit or Bosch paths. This particular companion behavior does not seem to occur in sensor or repeater nodes since their BLE is off.

charset=UTF-8 Content-Transfer-Encoding: 8bit AUTO_OFF_MILLIS is a power-save feature aimed at battery use. When the board reports isExternalPowered() == true (USB or other DC source), blanking the screen serves no purpose — there's nothing to conserve. But OLEDs are vulnerable to burn-in with static content, so this behaviour is gated behind a new build flag KEEP_DISPLAY_ON_USB. Default is unchanged from upstream — the display blanks after AUTO_OFF_MILLIS on USB or battery. Variants that ship with an LCD instead of an OLED (e.g. heltec_t096) can opt in by adding -D KEEP_DISPLAY_ON_USB to their env, gaining always-on-while-powered without exposing OLED users to burn-in risk. When the flag is enabled, the implementation refreshes _auto_off every loop iteration while externally powered, so the timer naturally counts a fresh AUTO_OFF_MILLIS window from the moment power is removed — no instantaneous-blank-on-unplug. Applied to all three companion_radio UI flavours (ui-new, ui-tiny, ui-orig). Boards without an isExternalPowered() override use the base-class default in MeshCore.h (returns false), so battery-powered behaviour is unchanged everywhere.
