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 course.

I already have a gnuradio block that would pass my a raw data of the message from that start of frame. Right now the messages are saved into a text file by connecting this block to a file sink. I'm not sure how I read each message and analyze them. I don't know much about programming in gnuradio/python. Can someone suggest me what to do? Thank you very much, Rithirong Thandee 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.
