Hey all,
I'd like to know how to write short files of streamed USRP data
periodically using GNUradio. For instance, I'd like the USRP to
automatically record 5 seconds of data every 10 minutes. It does not
matter to me whether the USRP is constantly on and most of the data is
being discarded, or if the USRP wakes up every 10 minutes to record
the data before sleeping. Whichever is easiest to achieve is fine by
me. Does anyone have experience doing this kind of thing?

If you're using Gnu Radio, you can simply use the file sink, and have it
record to "/dev/null" most of the time, then have something (perhaps via
the XMLRPC built-in feature) change the filename to whatever your
desired filename is, and then revert it back to "/dev/null".
I think I said the same thing on the discuss-gnuradio mailing list a few
days ago.
The usrp-users mailing list isn't the best place to ask Gnu Radio
questions, a question like this, which is inherently radio-type
agnostic, probably
belongs on the discuss-gnuradio mailng list, because it's more about
"how do I make Gnu Radio dance".
