Problem with the GNURadio.

[tomcass240]

I am getting a strange problem with the GNU-Radio when opening the telive_1ch_gr37_udp_xmlrpc_headless.py script. When running it in GNURadio (after replacing the missing blocks) I get an error message:

Executing: /usr/bin/x-terminal-emulator -e /usr/bin/python3 -u /home/z/telive/gnuradio-companion/receiver_xmlrpc/top_block.py

E [main.cc:414] Error: execvp of /usr/bin/python3 -u /home/z/telive/gnuradio-companion/receiver_xmlrpc/top_block.py: No such file or directory (errno=2)

The strange part about it is that the file is exactly where it's supposed to be and copy/pasting the command opens up an x-terminal just fine. I've moved the folder around to different locations and tried running it again and still get the same error.

I'm not very good with all this programming stuff and I don't even know where main.cc is to try and see what's causing this problem. It seems like it should be so simple to fix but I have no idea what could be causing this issue. The

did you try the source code from osmo-tetra? I saw that it supports encryption, but only for those who know how to find a key, Jaceck will make many fixes in his code in the future

I'm not sure what source code you're referring too. Are you talking about tetra-rx? I just used the source code from this repo. I'll try the osmo-tetra repo code if you think it's worth a try. There were so many bugs in this repo's code, mostly simple bugs that even I could fix, but I don't think I'm going to be able to get it working. I can't see receiver1udp making a connection on port 7379 and only see the gsmtap port on 4729.

nice, thanks for the advice man, I got it working, kind of. For some reason I couldn't compile the tetra-rx executable and was getting an error message but I just copied it from the other directory and it seems to be working, at least receiver1udp is. I'm getting loads of text through so it's definitely getting a signal (unfortunately it's encrypted).

I'm not getting anything in the telive window though. Does it ignore encrypted channels entirely?

The original osmo-tetra will not send packets to 7379 (which are later consumed by telive)

does it show signaling and crypto parameters like Frame number and IV ?

[tomcass240]

I can't get it working again, but from what I remember it did show all that information yes. It was scrolling down the page with all that stuff, it just said it was encrypted. The information was in the tetra-rx window not telive.

I updated telive and osmo-tetra and I'm getting a new error from the script:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.11/xmlrpc/server.py", line 594, in __init__
    socketserver.TCPServer.__init__(self, addr, requestHandler, bind_and_activate)

    self.socket.bind(self.server_address)
OSError: [Errno 98] Address already in use

>>> Done (return code 1)

If that's the only error I am getting now then I'm hopeful I might be able to get it working.
