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, CoAP over WebSockets has now been implemented for the most part in the current development version (3.1.x).
