I searched the Asterix CAT 240 protokol decoding in wireshark. I want to decide whether or not the CAT 240 is based on the captured packages in wireshark. Is this possible? I want to see all necessary fields. Is there built-in support of Wireshark for this work?

Unfortunately for you the current Asterix dissector does not support category 240 message dissection. Either no one has created it, or it has not been submitted for inclusion in the repository.

Which Asterix category messages can be supported in Wireshark ? (i.e: 034, 048 ...etc)

Probably all of them, it's just a matter of adding the code to the dissector. Once someone finds the interest to add it, that may happen. If you can't do it yourself, you can always file an enhancement bug report, preferably with a sample capture file.

FYI, bug reports are made at the Wireshark Bugzilla.

Hello again. How can I add a dissector ability for received packets? Should I write an custom script ? Can you give an application note or reference code for dissector the received packets?

The code for the existing dissector is here and this is the file to which the code should be added.
