I am trying to use LoRa connectivity with the brand new b-l072z-lrwan1 discovery board. The End Node project works perfectly but I have an issue with the AT Slave project. When I try to send LoRa packet to my Multitech gateway, this one never receive the packet and I cannot use AT command with the disco board anymore. I can only do a hardware reset of the board.
As you can see on my screenshot, the Join process has been done correctly. After the AT+SEND command I never receive a status like OK or AT ERROR.
Are you able to help me ?
Thank you !
