Hi all,

is there a mailing list to discuss general CoAP issues?

I think there is a conflict between rfc 7641 for observing resources and the draft for CoAP over TCP. To cancel an observation the observer should send a RESET message to the observed resource. This is not possible when using the TCP transfer because RESET messages are part of the reliability mechanism not included in the TCP spec.

Is there any work done on the observable spec? Or is that dead?

Thanks for answers or for pointing me to a better place to discuss this!

Cheers,

Martin
