Minimal CoAP Client and Server Examples for libcoap

These examples require libcoap-3 with a minimum version of 4.3.2 to compile and execute.

client.cc is a minimal libcoap client that sends a confirmable UDP GET /hello request to a pre-defined CoAP server (coap.me in this example) and outputs a received response. It supports an optional argument which can be a different CoAP URI to send the request to. If the host is a multicast address, then this is handled by a NON-confirmable request.

server.cc is a minimal CoAP server that binds on ::5683, as well as the multicast IPs 224.0.1.187 and ff02::fd. It has two defined resources /hello and hello/my along with the inbuilt resource .well-known/core.
