Hi,I made a Flowgraph in GNU Radio which shows me the FFT of the samples that are sent by a Raspberry Pi over TCP. It looks like this:
Osmosdr Source -> Stream to Vector -> FFT -> Complex to Mag -> Log10 -> Vector to Stream -> Moving Average -> Stream to Vector -> Probe Signal Vector
I want to save the values of the FFT in a list in my Python program later. Now what I tried to do was to plot the probed vector with Matplotlib. I also replaced the last Stream to Vector Block and the Probe Block with a QT Time Sink to control the output. But the picture I get with Matplotlib is totally different. So my question is if this is a problem of how to do the probes on the signal vector or if it could be a problem of Matplotlib.
Thank you in advance!
