Hi to whom it may concern, I am an amateur in the GNU Radio SDR project and would like to learn more for my work as a ground station Engineer from Singapore working in a tertiary institution. I would like to learn how to convert FFT signals(500 sample points) to data streams and csv files as I n

Evgany: Excellent work solving your problem. That’s the most important thing! I think what you’ve done is still the preferred method by many as dynamically packetizing data in GNURadio is still a bit application specific. If you are up for installing GNURadio 3.9 the tutorial works perfectly in

Hi Paul, I tried to perform a similar experiment and unfortunately after investing a significant effort, still haven't figured out how the packets method works :( For now, I pack the data in python, send the packed data to GNURadio and LimeSDR_Tx. and on the Rx side, I detect by LimeSDR_Rx, perfor

Hi Mike, It looks like the streamed videos from twitch have disappeared (as they do after a couple weeks). Official support for the "custom buffers" functionality will be a part of the 3.10 release, and I'm working on putting together a gr-cuda OOT that will capture the basics of how to use these
