Has anyone out there done any work with CoAP?
And the Observe (subscription) extension proposal:
I am implementing it for my day job for an embedded system. I am doing it from scratch using just the RFC for reference.
I am thinking of doing another implementation (not using any work code, of course) for the Arduino. I’ve found a few attempts to implement it, often with many missing features or missing many needed features.
Anyone out there a CoAP expert?
