The packet format block is not a GNURadio “in tree” block but rather a “python
embedded” block. It’s a block created specifically for this tutorial that
requires no installation.

Paul M., glad my flowchart worked for you :)
Paul A., Thanks for the detailed reply.
Can you clarify what is the embedded Python block when you write "The
access code is created in the embedded Python block" ?

Hi!
Here are my answers:
1. The access code is created in the Embedded Python block, and is

Oh sorry for the confusion, I'm NOT running gnuradio from the pycharm
venv, I just put the folder there so pycharm handles the version
control.
Just in case, I did what you suggested, but the same as before
happened (new log attached).
I've just finished setting up a VM and both flowgraphs work, s
Glad to hear you didn’t give up!
H. I haven’t seen this one on my machines. I see you’re using pycharm
(which is what i use). I think I had to setup pycharm to find GNURadio. IIRC
Pycharm typically sets up its own environment, so it might be missing a module?
That may not be valid, just my f

Thanks so much for replying! I was actually about to give up after all.
I've tried to use the updated flowgraphs from the wiki, but got an

Barry, can you fill in where my understanding is weak here?

Excellent work solving your problem. That’s the most important thing!
I think what you’ve done is still the preferred method by many as dynamically
packetizing data in GNURadio is still a bit application specific.
If you are up for installing GNURadio 3.9 the tutorial works perfectly in
Hi Paul,
I tried to perform a similar experiment and unfortunately after investing a
significant effort, still haven't figured out how the packets method works
:(
For now, I pack the data in python, send the packed data to GNURadio and
LimeSDR_Tx. and on the Rx side, I detect by LimeSDR_Rx, perfor
