STM32CubeWL LoRaWAN ATSlave and endpoint example assistance

[CLind.1]

Hi, I've been trying to figure out how to get the above-mentioned LoRaWAN examples working on a STM32WL5 devkit.

I'm at the point where I can join with OTAA on a Multitech gateway on the Things network, but I can't seem to get the devkit to then send any more packets.. Could someone please assist?

Regards
