Contribution description
The
nanocoap_sock_request_cb()function performs one CoAP request. Since it re-uses the socket between requests, stale responses can accumulate (especially in the non-confirmable case).Those are of no use - clear them out before sending a request so they don't fill up the sock's rx queue.
