I am implementing RFC 8323 for CoAP. I am not able to see coap header in wireshark when i send coap packet over TCP and websockets. Is there any version or disector available for the same.

Currently CoAP only registers for traffic over UDP (on a user specified port) and DTLS.

To allow CoAP dissection over TCP requires a change to the CoAP dissector, enhancement requests should be added to the Wireshark Bugzilla or code changes to the Wireshark Gerrit instance.

The reporter has opened a bug report at https://bugs.wireshark.org/bugzilla/s..., CoAP over WebSockets has now been implemented for the most part in the current development version (3.1.x).
