Good morning,
I am using CayenneLPP to pack the sensors(RAK1904, RAK1906, RAK5801 and RAK12500) values read and library SX126x-Arduino to send the LPP package to LoRa Server.
I am using “Radio.Send”(from Radio.h in teh SX126x folder) but it is not working as I was expecting, I mean the LPP package is not being sent.
Could you help me to find the correct function and the way to send the LPP package?
Regards,
Claudio
