To complete this demonstration of running a TCP server from within the
GNU Radio Companion flowchart without modifying the generated Python code,
and correcting a mistake in the post below so that I can also update the Signal
Source frequency, I have uploaded

Thanks to this comment, I ended up finding a solution to call a thread
running a TCP/IP server able to control the variables from the main
processing flowchart, without modifying manually the generated Python for a Qt
application.
A screenshot, which I hope is self-explanatory, illustrating this pr
I am definitely not knowledgeable about Python so I might be missing
the basics: as I want to include a TCP server for tuning the acquisition
parameters, it seems to me (but I might be wrong) that the Python Module
is more appropriate than the Python Snippet which seems to add a piece
of code to th
Seems like you already understand the limitations! Good luck with you

The envisioned application is event driven: send a control word from a client,
wait for the even to complete (e.g. move antenna to target position), start
streaming data for a given amount of time, and when enough data is collected
move
to new position. Of course timing cannot be relied on with a
It might be difficult to control GPIO with precise timing on raspberry pi
depending on what you want to do... A few hundred khz might be ok though.
libgpiod is the new better Linux GPIO API.

It gets even better:
We've launched a feature in 3.8.1.0 (and on master before that, as we do
with any feature that ends up in a maintenance release) that we hope
doesn't come back to bite us due to enabling unclean design. But, we
must build best practices so that it doesn't go unused, either

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 wit
