Detecting whether a non-confirmable message was received or not #11

Open cdh4u opened 4 years ago

Section 4.3 says:

“At the CoAP level, there is no way for the sender to detect if a Non- confirmable message was received or not.”

If the message is a request, and the sender receives the associated response, that does indicate that the message was received.

Similarly, if the message is sent empty, and triggers a Reset, the receival of that Reset indicates that the request was received.

Thanks! Indeed, some information about the reception of a Non-confirmable message can be inferred if that triggers a reply. I guess section 4.3 could be clarified in that sense.
