I seem to be having no luck getting the wireshark output to work monitoring a P25p1 system. I have enabled it ( -w) and verified that scope.py is loading the p25_decoder object in which the wireshark flag and port are passed to.. however if I use nc or a python script to listen on 23456 (or wireshark) I'm not getting a thing.... any thoughts?
Cheers
Same problem, what version of plugin did you use, I was only able to install 1.6

I believe 1.6 as well- but wireshark aside, I don't believe op25 scope is pushing out any data over UDP to begin with....
it's possible there's been a mismatch between the C code and the python as the code has evolved. In p25p1_fdma.cc there is a line (at line 337 in my copy of the file) if (!d_do_imbe) { try changing this to if (1) { and also there is a line below this (356 in mine, not the one at 317) if (d_do_output) { which you would change to if (0) { you have to uninstall and then do the standard make / make install after this.
Also make sure the wireshark hostname and port are set, I think if the port number is defaulted to zero that will cause no output. Also if you're writing to localhost you'll need to run wireshark on the localhost interface not the ethernet one.

Same problem I have. Get data ok using grgsm ,just not op25

I haven't had time to dive into the source yet, but I may just fork it on github so people can get a working version if they run into the same problem in the future.
