Contribution description
We don't want to copy the payload into a separate buffer together with the CoAP header when sending.
Instead make use of
sock_udp_sendv()and use two packet snips, one for the header and one for the payload.Testing procedure
examples/nanocoap_serverstill works, but now the response to "/riot/board" is no longer copied into the reply buffer, but just referenced.Issues/PRs references
depends on and inludes
#17544
