Hi everyone

Quick question.. i know GRC can read any file extension i.e. *.txt, but how can i see the data i save on a file sink? to be clear let me try a quick test.. randomsource-->throttle-->filesink..

when i try to see the exit of the random source my gedit says thats it doesn't recognize the format..

thanks

Basically, you're writing a binary file, so a text reader won't know what to do with it (you could use emacs in hexl mode, though).

There are a handful of plotting tools in the current releases of GNU Radio that you can use, named gr_plot_xxx (where xxx = float, int, iq, const, etc.). These use scipy.fromfile to read in the binary data.
