It depends what you mean by readable format. If you just want to get an idea of the values and the file isn't to big then do:
from gnuradio import gr src = gr.file_source(1, "the_file_name") snk = gr.vector_sink_b() tb = gr.top_block() tb.connect(src, snk) tb.run() # The bytes will be presented as a list of integers in python. data = snk.data() print(data) On Tue, May 22, 2012 at 9:47 PM, ambily joseph <josephamb...@gmail.com> wrote: > Sir > My file sink input type in 'bytes'...Smthng being written to that > folder..nd size of that file is increasing,,but when i try to open it its > octet-stream file...How can i make into a readable format? > > > On Mon, May 21, 2012 at 7:44 PM, Ben Reynwar <b...@reynwar.net> wrote: >> >> On Mon, May 21, 2012 at 12:19 AM, ambily joseph <josephamb...@gmail.com> >> wrote: >> > Sir >> > >> > I am trying to build an SID SDR receiver,,where i require a file sink... >> > When i run my flow graph,,i get a file of format octet-stream being >> > written >> > into my computer. >> > But i am not able to access or open my dat octet-stream file. >> > Sir may i know how can i access the data being written into it? >> > >> > Thank you >> > >> > _______________________________________________ >> > Discuss-gnuradio mailing list >> > Discuss-gnuradio@gnu.org >> > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio >> > >> The file sink is just a dump of the data stream.
