This first round I’m just listing first n hits from googling and summarising a quick peek inside in few lines https://github.com/dgiannakop/Arduino-CoAP Looks otherwise fine, but is hardcoded for XBee only. Refactoring for IP/XBee would require inventing and implementing an abstraction layer not yet present and looks like a lot of work. https://github.com/telecombretagne/Arduino-IPv6Stack These guys have COAP and IPV6 they claim to be perfectly suitable for us. It is already abstracted between layers and is ported from Contiki. Very promising on the surface. It looks as though most google hits are short blog entries or others reflecting back to either of these, or just unanswered questions related to the generic area. - t
