My approach:
* build your grc chart from GNU Radio Companion and generate the .py file
* edit the py file and import pygpio
* play with the RPi4 GPIO in your python script.
See attached script, with a python server included in the Python script
to control an RF switch from a GNU Octave TCP/IP client talking to the Python
TCP/IP server.
I am presenting this approach to hardware control at

If you use "Python Module" block, you can write a lot of
non-GnuRadio-esque python, import anything you want, etc, etc. No editing
of the output python required, necessarily.

Hi All, does anyone have an example of how to control GOIO lines on the RPi4
from within a GRC
flowgraph. I’m guessing it’s an OOT module.
I need to generate a signal of a few 100Hz & control GPIO lines at various
points though the cycle.
Alternatively, I could generate the signal & lines with external hardware &
read them with
GnuRadio.
Tnx, Dave
