I am sending CCSDS packets in the form of a UDP payload and would like to decode the payload as such. Is this possible? What I have tried to do so far is select the UDP payload and then select "decode as", but CCSDS is not in the list. It appears that only lower-level link layer protocols are in there like CAN bus and USB, but not realy sure why I can't apply CCSDS there as well.

What did you do to get the list?

Unless you have a really old version, you need to:

  • select the packet;
  • select Analyze > Decode As...;
  • click the + button;
  • double-click the value in the "Current" column for the newly-added row (it probably says "(none)");
  • clock the button on the right with "^" above "v".

That list shows CCSDS in the version of Wireshark I have.
