firmware master branch: Build Status
firmware beta branch: Build Status

The maintained main firmware for the Sensor.Community / Luftdaten.Info Sensor.

A transitional firmware which will look for a firmware file stored on SPIFFS to replace itself with for next reboot or do an endless loop of panic LED blinking if this fails.

This allows to do an Over-the-air (OTA) procedure on setups that have a 1M/3M split layout (rather the more modern 2M/2M) for firmwares larger than 512k (up to ~ 740k).
