This version is extremely outdated and is not maintained. The Standard can be down loaded here. Responds to GET, HEAD, POST requests, but will fail on anything else. There seems two ways to test the DK: to use Phyton example as defined in documentation and through IPv4 tunnel connection from PC. Approved 2013-07-11 as draft-ietf-core-coap-18, it has been published as RFC 7252 on 2014-06-26 (the delay having been caused by waiting for some related security specifications to finish their publication process). It comes with an add-on node-red-contrib-coap and provides a coap-request node for making requests to the CoAP server. The server address used here is an example address and will need to be modified based on the server address of the nRF5 device that runs the server application. Programming for IoT is usually a polyglot (multiple languages) effort since the Internet-of-Things (IoT) is a system of inter-related computing devices that are provided with unique identifiers and the ability to transfer data over a network. 0 becomes OASIS Standard Click above for the press release.
