[Discuss-gnuradio] Can a message sink save data to file(s)?

[Prachi Parihar]

Hi everyone,

I am working with uhd_fft.py and have made some changes and gotten the data to display as desired using fft_sink_c. However, in addition of displaying the data, I would like to save the data to either a single file (append the incoming messages) or to a series of files. Is there a way to send the messages to file(s) so I can save and analyze the data (using another application)? 

Thanks in advance,

Prachi
