I have a rak11720 breakout board but after around 120-140 send messages i just get this message every time a send should be a lora transmission:
23:35:01.102 → Data Packet:
23:35:01.102 → 0x74 0x65 0x73 0x74
23:35:01.146 → Sending is requested
23:35:09.257 → Sending failed
23:35:09.257 → +EVT:SEND_CONFIRMED_FAILED(4)
I dont get any data so its not a confirmation problem. At first i throat that it was something in my costume arduino code, but i have just run a test in the lorawan otaa example and it gives the same result. I have checked the incoming data in my gateway and have come to the conclusion that the node dont send a message. Are there anyone else there have run into this issue and have a solution?
