Thanks for your interest in the Intel® Galileo Platform.
I have no experience using CoAP, so I was looking information related to it and I have found these implementations for multiple programming languages as well as server/client examples that I believe you could find useful information:
However, regarding the issue you are having I’d suggest you to contact FreeCoAP (http://www.freecoap.org/) since they could give you a more accurate answer.
Thanks for your response. I will try to contact them. I must admit I was not able to find their contact address (but found a reference about the developer working in Intel).
I have already managed to get COAP working with another project (microcoap). What FreeCoap claism to have resolved, and it is part of what I am trying to obtain, is the secure communication using the DTLS that the COAP RFC sets as standard. Looks like this secure comm is in the TODO list of almost every COAP project.
