Can't it be done with a pipe? What I mean is, use the radio API to get the data and store in a pipe. In julia, the main process would read from the pipe and run your algorithms on it. If necessary, it could hand the data to another process.
I've done something similar to read data from a sound card in real time, using sox and octave. Sox reads data from the sound card and sends it to a pipe, which in turn is read by octave. Works great. You can use the same idea to have bidirectional data. -- mb On Mon, Apr 7, 2014 at 2:01 AM, Elliot Saba <staticfl...@gmail.com> wrote: > The main sticking point I've had so far is getting data from the radio in > realtime.
