Wisnode Lora AT Firmware and WisTrio5205
I've acquired a Wisnode Lora that seems to be running the last AT firmware found in RAKWireless/RAK811/RAK811_V2030_20180731.bin which is Version 184.108.40.206.
I would like to know if the source code is available somewhere ?
I only found the Class A & C CoIde projectcs, but nothing about AT Command source code.
My goal is to understand how the Downlink works to activate or implement it in a WisTrio 5205 Class A.
