I am pretty sure we did this under some kind of Linux, and I think it was SuSE. > I'm trying to do so, but I'm encountering problems.

The barker code demod defaults to off (probably not a wise choice). Make sure it's on - I suggest reading the code and the option parsing in particular. This is all a bit rough. I definitely received 802.11 packets (1 Mb/s) under NetBSD. So while I'm sure there are things wrong, it's possible to make it work. See the tap example; that's what I ran most recently. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
