Dear list members,
I’m sorry to bother you with the classic newbie stuff, but I’m stuck -
since some days (the solutions found on the web didn't work for me) - to
this point:
- gnuradio-companion RaspberryPi 3b + hackRF one with a very simple
blocks flow doesn’t display any signal window;
and the error message I get is the following one:
- - - -
Warning: failed toXInitThreads()linux; GNU C++version 6.2.0 20161010;

I'm trying to follow some very nice youtube tutorial (Ossman, Hackaday
etc. ) but I cannot proceed if I can't neither make grc working with a
simple sketch.
Any help is greatly appreciated.
More, if you have any suggestion or advice, here it follows a general
description of the process I want to develop for my sound-art / sdr
based installation.
The set up should be as follows:
- a small robot(flor hover type) moves randomly in a restricted area
(few sq meters)of a big room.
On this device, an RPI(“A”) + [DVB-T+DAB+FM] usb dongle,
battery-powered, is mounted to detect some RF activity in some rf range.
Some values should be extracted (intensity over time of a particular
freq // and intensity of shifting detected frequencies). The movements
of the robot in the room should cause different detected values.
- these values should be shared or sent in real-time to an external
software (PureData) that sends these values via OSC to another RPI(“B”),
which is steady, that will use the incoming values as a control signal
for some audio DSP-treatments (sampling and granulation). The raw audio
material for dsp audio treatments will be just RF noise.- The audio
treatments will be played inside the room via loudspeakers.
- through a microphone and dsp, the live audio stream will be analyzed
in PureData (intensity and spectrum-centroid) in real-time by the steady
RPI. The values extracted from the audio-domain should be sent to
GNURADIO-COMPANION to transmit some signals via HackRF one in the very
same frequency range which is detected by RPI(“A”).
- the idea is to build a close circuit of information generation, which
should be modulated over time and ever-changing, due to the conversion
of values between the domains radio/audio, and to the implication of the
room acoustic response analyzed and encoded to interfere in the
radiowaves domain.
The suggestion of this idea comes from the works of Agostino Di Scipio
“Audible Ecosystemics” (2000-2005) which develop very deeply feedback
network processes based in the pure audio/acoustic domain. My purpose is
to try to do something similar in a cross-domain set (Radio/Audio
through Sonification and Dsp treatments)
thank you very much for your kind attention and help,
best
Stefano Zorzanello
