Unable to get LoRa P2P up with ATSAMR34

Question

I am new to LoRa.

We have a custom board built with the schematics provided for ATSAMR34. I am able to flash it with basic images and get it functioning for serial communication.

I tried to to build and flash images for LoRa P2P, as provided in https://github.com/MicrochipTech/atsamr34_long_range_p2p

While the image is in, LoRa is not getting active. Both microcontroller boards are connected to the same laptop, on 2 different USB serial interfaces, COM6, COM8.

           Power on the board until LED 1 lights up
           to indicate connecting with peer.

           LED 1 will be toggled upon receiving messages.

Could some one help me out to get LoRa up?

I tried googling to understand how this is supposed to work, but I had not much of luck there.

Answer 1

Periodic Transmission = Disable

I haven't used these examples, but if there's no periodic transmission, nothing is going to happen... Could you try enabling it on one of the devices?
