Issue: Cannot find documentation regarding custom firmware for Rak5010
Setup: Rak5010, Arduino IDE.
Details: I need to configure my Rak5010 board to read all inbuilt sensor data and send to my MQTT server as JSON. I cannot find any documentation on this, and as per my knowledge Rak5010 has no RUI support. How can I achieve this? Is it possible with just AT commands or other workaround?
