   Closed because the issue was not in the code. We have CoAP ported from ContikiOS, which follows RFC 7959 and received messages came from system following RFC 8323. Between these versions were introduced new message type - CSM, which is sent at the beginning of every connection. If device following newer spec doesn't receive response for CSM message (and it doesn't, because we do not handle these), it disconnects.
