Firmware

Install PlatformIO CLI

First of all you need to follow the installation guide

Building

You can easily build the firmware using platformio CLI commands.

cd firmware #ensure you are in the firmware directory (in firmware repo)
pio run

By default after build binaries are copied into /tmp/fkm-build folder. Development binaries are marked with their build time (epoch seconds).

Flashing

To easily flash firmware on the device, you can use the built-in OTA (over the air update) in the micro-connector.

By default micro-connector is watching /tmp/fkm-build dir for firmware changes.

To flash development firmware you need to add DEV environment variable. If you are running micro-connector using cargo (not docker) you can change that in .env file in project dir.

Common issues

1. If you aren't using DEV mode your firmware won't be updated to the development version of firmware.
