Ernest - here's an example of how to connect other stuff to GNU Radio via pipes - granted at much lower sample rates. Higher sample rates shouldn't effect the pipe, but Matlab may not keep up with a typical 802.11 sample rate.

If you're doing processing in another framework, why don't you just use UHD directly w/out GNU Radio? There are finite acquisition calls in UHD IIRC... -John On Fri, Oct 17, 2014 at 5:15 AM, Martin Braun <martin.br...@ettus.com> wrote: > On 10/17/2014 12:40 PM, Ernest Szczepaniak wrote: > > So i if would like to create a simple flow graph, with USRP source and > file > > sink only, is there any way to control file buffer size (i.e i want that > any > > file consist of 3k 32complex samples every write)? > > You can't control how many samples the USRP source will produce per run. > And I'm not sure that's really what you want. > > > Any 3.7 compatibile pipe pack? tried gr-pipe but typical "gnuradio-core" > > error :( > > I was suggesting you create a named pipe instead of a regular file.
