You’ll have to somehow convert and decode the raw samples into data and
dump them as perhaps a PCAP file that can be analyzed in Wireshark.
More general question – would it make sense for GNU Radio to have
decoders than can dump to PCAP files? I noticed there are already TCP
and UDP sinks, for instance, but they’re not exactly the same things of

Thank you very much,
In my opinion packet analysis isn’t the proper job of Gnu Radio itself.
What you can do is have your output file be a “FIFO” file (named pipe),
and then attach an external analysis program to that FIFO, and write it
in whatever you’re comfortable with.
