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
