Hi, I am using Nucleo-F401RE board, X-NUCLEO-S2868A1 expansion with S2LP and X-CUBE-SUBG1 software. Using code from udp sender and receiver examples, modified to each node be able to send 6LoWPAN message to other node, and answer to message back. When node receive uart trigger it send 8 bytes to other node and those node answers with ack packet.
My problem is sometimes while new node power up happens next:
It is receiving packet, but not sending ack back (send function for ack called, but no real packet appears in sniffer and RF analyzer)
Some other node stops sending ack back
While I restart (sometimes need few times) sender and receiver node, it starts work ok.
Have someone has similar issue? And maybe way to fix it?
