I nucleo lrwan1

I’m using i nucleo lrwan1 and nucleo l073rz board.

After connecting the device to the power, I confirmed that it sends JoinRequest and receives JoinAccept.

But no uplink messages since then.

I checked from TTN, there is an uplink every 30 seconds, but I couldn’t see any uplink messages from ChirpStack.

Could you help me?

Hi , I use the same shield with nucleol053r8 board but i can’t get connexion between those two boards can you please tell me how did you fixed it?!
