For GPRO project, just a page to collect the presentation material, links, etc, for the CoAP simple intro.  This is not intended to be a perfect presentation (CoAP is a minor protocol in this project and there are surely other better presentations and pages - please add more links if you find them)


IETF standard, RFC 7252:
"[CoAP is...] similar to the client/server model of HTTP.  However, machine-to-machine interactions typically result in a CoAP implementation acting in both client and server roles"

Summary: CoAP is like HTTP for constrained environments. If you want to use HTTP/RESTful services but more bandwidth efficient, runs on unreliable networks.
