Please define DISPLAY_SIZE." set according to similar devices. * Put guards in place around debug heap operations (#7955) * Put guards in place around debug heap operations * Add macros to clean up code * Add pointer as well * Cleanup * Fix memory leak in NextHopRouter: always free packet copy when removing from pending * Formatting * Only queue 2 client notification * Merge pull request #7965 from compumike/compumike/fix-nrf52-bluetooth-memory-leak Fix memory leak in `NRF52Bluetooth`: allocate `BluetoothStatus` on stack, not heap * Merge pull request #7964 from compumike/compumike/fix-nimble-bluetooth-memory-leak Fix memory leak in `NimbleBluetooth`: allocate `BluetoothStatus` on stack, not heap * Update protobufs (#7973) Co-authored-by: thebentern <9000580+thebentern@users.noreply.github.com> * T-Lora Pager: Support LR1121 and SX1280 models (#7956) * T-Lora Pager: Support LR1121 and SX1280 models * Remove ifdefs * Trunk * Trunk * Static memory pool allocation (#7966) * Static memory pool * Initializer * T-Lora Pager: Support LR1121 and SX1280 models (#7956) * T-Lora Pager: Support LR1121 and SX1280 models * Remove ifdefs --------- Co-authored-by: WillyJL <me@willyjl.dev> * Portduino dynamic alloc * Missed * Drop the limit * Update meshtastic-esp8266-oled-ssd1306 digest to 0cbc26b (#7977) Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> * Fix json report crashes on esp32 (#7978) * Tweak maximums * Fix DRAM overflow on old esp32 targets * Guard bad time warning logs using GPS_DEBUG (#7897) In 2.7.7 / 2.7.8 we introduced some new checks for time accuracy. In combination, these result in a spamming of the logs when a bad time is found When the GPS is active, we're calling the GPS thread every 0.2secs. So this log could be printed 4,500 times in a no-lock scenario :) Reserve this experience for developers using GPS_DEBUG. Fixes https://github.com/meshtastic/firmware/issues/7896 * Scale probe buffer size based on current baud rate (#7975) * Scale probe buffer size based on current baud rate * Throttle bad time validation logging and fix time comparison logic * Remove comment * Missed the other instances * Copy pasta * Fix GPS gm_mktime memory leak (#7981) * Fix overflow of time value (#7984) * Fix overflow of time value * Revert "Fix overflow of time value" This reverts commit 084796920179e80a7500d36c25fd4d82b3ef4214. * That got boogered up * Remove PMSA003 include from modules * Add flag to exclude air quality module * Rework PMSA003I to align with new I2C scanner * Reworks AQ telemetry to match new dynamic allocation method * Adds VBLE_I2C_CLOCK_SPEED build flag for sensors with different I2C speed requirements * Reworks PMSA003I * Move add sensor template to separate file * Split telemetry on screen options * Add variable I2C clock compile flag * Added to Seeed Xiao S3 as demo * Fix drawFrame in AQ module * Module settings override to i2cScan module function * Move to CAN_RECLOCK_I2C per architecture * Add reclock function in TelemetrySensor.cpp * Add flag in ESP32 common * Minor fix * Move I2C reclock function to src/detect * Fix uninitMemberVar errors and compile issue * Make sleep, wakeUp functions generic * Fix STM32 builds * Add exclude AQ sensor to builds that have environmental sensor excludes * Add includes to AddI2CSensorTemplate.h * SEN5X first pass * WIP Sen5X functions * Further (non-working) progress in SEN5X * WIP Sen5X functions * Changes on SEN5X library - removing pm_env as well * Small cleanup of SEN5X sensors * Minor change for SEN5X detection * Remove dup code * Enable PM sensor before sending telemetry. This enables the PM sensor for a predefined period to allow for warmup. Once telemetry is sent, the sensor shuts down again. * Small cleanups in SEN5X sensor * Add dynamic measurement interval for SEN5X * Only disable SEN5X if enough time after reading. * Idle for SEN5X on communication error * Cleanup of logs and remove unnecessary delays * Small TODO * Settle on uint16_t for SEN5X PM data * Make AQTelemetry sensors non-exclusive * Implementation of cleaning in FS prefs and cleanup * Remove unnecessary LOGS * Add cleaning date storage in FS * Report non-cumulative PN * Bring back detection code for SEN5X after branch rebase * Add placeholder for admin message * Add VOC measurements and persistence (WIP) * Adds VOC measurements and state * Still not working on VOC Index persistence * Should it stay in continuous mode? * Add one-shot mode config flag to SEN5X * Add nan checks on sensor data from SEN5X * Working implementation on VOCState * Adds initial timer for SEN55 to not sleep if VOCstate is not stable (1h) * Adds conditions for stability and sensor state * Fixes on VOC state and mode swtiching * Adds a new RHT/Gas only mode, with 3600s stabilization time * Fixes the VOCState buffer mismatch * Fixes SEN50/54/55 model mistake * Adapt SEN5X to new sensor list structure. Improve reclock. * Improve reClockI2C conditions for different variants * Add sleep, wakeUp, pendingForReady, hasSleep functions to PM sensors to save battery * Add SEN5X * Fix merge errors * Update library dependencies in platformio.ini * Fix unitialized variables in SEN5X constructor * Fix missing import * Cleanup of SEN5X class * Exclude AQ sensor from wio-e5 due to flash limitations * Fix I2C clock change logic * Fix trunk * Fix on condition in reclock * Add check on polling interval of sen5x --------- Co-authored-by: Hannes Fuchs <hannes.fuchs+git@0xef.de> Co-authored-by: Nashui-Yan <yannashui10@gmail.com> Co-authored-by: Ben Meadors <benmmeadors@gmail.com> Co-authored-by: Tom Fifield <tom@tomfifield.net> Co-authored-by: Mike Robbins <mrobbins@alum.mit.edu> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: thebentern <9000580+thebentern@users.noreply.github.com> Co-authored-by: WillyJL <me@willyjl.dev> Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com>
