Is the Lora-E5 AT factory firmware compliant with TTN V3?


I’d like to connect to TTN V3 and would like to know, whether the factory firmware is fully compliant with TTN V3?


Lora E5 is a fully compliant Lorawan device so it works perfect with TTN V3 ! You can connect it with TTN V3 using the AT command without any difficulties :wink:
Did you get a look at documentation of device ? Grove LoRa E5 - Seeed Wiki

Yes I did … It seems to me that the example, how to connect to TTN, is for the TTN V2 stack, since the payload decoder shown uses function Decoder(). In TTN V3 the decode uplink function is called decodeUplink().
