You should be able to read the output of that command with . Make sure that you use the --file option before your output file name. I tried the command you ran and didn't get any output because I didn't have --file before the output name. Maybe a version difference?
By default it seems that the rx_samples_to_file saves samples as SC16 (short complex 16 bit). I had assumed it would be FC32 which would require the use of  to read. You can change the output format (CPU format) with the --type option. Check the output of --help to see the type options.  https://github.com/gnuradio/gnuradio/blob/master/gr-utils/octave/read_cshort_binary.m  https://github.com/gnuradio/gnuradio/blob/master/gr-utils/octave/read_complex_binary.m On Mon, Jul 9, 2018 at 6:25 AM Wass Mailing <wass.mail...@gmail.com> wrote: > Hello everyone, > > I am new on Gnu Radio, and I saw that it was possible to save images of a > signal, however I would like to recover this signal in the form of data in > order to carry out a statistical analysis and to see the evolution on a > frequency wifi on which I circulate traffic and can make comparisons.
