Hello. Using End_Node sample application from ST…LRWAN v.1.2.3 I see only first Uplink contain the payload:
Second and all next Uplink messages is empty:
From device log I see that Uplink Frame with data size in 8 bytes was sent on Port 2.
Does anyone saw the same problem?
Where to look to troubleshoot such strange things?
Thanks for any suggestion and help!
