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.
