Every PR targeting develop has been red since 2026-09-07 on the seven ESP32 check jobs, while the nRF52, RP2040 and STM32 jobs pass on identical source. gh-action-firmware#61 moved the ESP32 container images onto the pioarduino core. Its esp32 platform ships its own tool-cppcheck 2.20.1 and reinstalls it over anything the repo pins, so ESP32 now analyses with cppcheck 2.20 while every other platform still resolves platformio/tool-cppcheck 1.21100.230717, i.e. 2.11. 2.20 parses far more of this tree than 2.11 ever managed, so checks that were always enabled fired for the first time: 388 defects, ESP32 only. #11776 cleared the two unknownMacro errors. Of the 386 left, two are worth acting on and are fixed rather than suppressed: * SerialModule dereferenced a null Position in NMEA/CALTOPO mode. `decoded` stays NULL when pb_decode_from_bytes() fails, but printWPL() was called with *decoded regardless, so a malformed position payload on our portnum crashed the node. Emit the waypoint only on a successful decode. * InkHUD's 12-hour clock passed a signed 12 to a %u conversion. The rest are style and performance suggestions - functionStatic and the const-correctness family account for 351 of them. Suppress those check ids so the gate means the same thing on every platform again, scoping the one-off ones to their file so a new occurrence elsewhere still fails. Burning them down is worth doing deliberately, not under a CI outage. Verified in the CI container images: all seven previously failing ESP32 environments pass, and rak4631, tracker-t1000-e and t-echo-plus still pass under cppcheck 2.11.
Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
