This is the firmware for this PCB: https://github.com/atoomnetmarc/Project-Decennium

OTA Password

Copy local_env-example.ini to local_env.ini and fill in your own hostname and ota_password.

Compile and uploading firmware

Compile firmware with platformio. I used Visual Studio Code with the PlatformIO extension.

You must also upload the firmware with platformio.

Wi-Fi configuration

When no Wi-Fi configuration is known then the firmware will start an access point on SSID decennium--something. Connect to it, then open http://192.168.4.1

When configured, pressing reset twice will also start the access point.
