Re: [Discuss-gnuradio] gssm_usrp.py usrp overrun?

[Joshua Lackey]

Sylvain,

Truthfully, that project is very old and I'm not surprised that you're
having issues with it.  I only keep the page up for reference purposes.

I recommend you check out the airprobe project.
( https://svn.berlin.ccc.de/projects/airprobe .)  This project is being
actively supported and should be a lot easier to get to work.

I'll put something up on the GSSM page that indicates this so that other
people don't end up wasting time trying to get gssm to run.
