Hi guys, has anyone tried to capture live 802.11b - 1mbit packets using the 802.11BBN source code in SuSE ? I'm trying to do so, but I'm encountering problems. First of all, when I run usrp_fft or usrp_oscope I can definitely see something. At least, I see power fluctuations due to my laptop's WLAN (old 802.11b) card. However, if I try to run ./bbn_80211b_tx.py I get the following error: " Using TX d'board A: Flex 2400 Tx MIMO B >>> gr_fir_ccf: using SSE spb: 8 interp: 32 Failed to set Tx frequency to 2.4G " I also tried to capture packets, using ./bbn_80211b_rx.py -d 8 -f 2412e6 -p , however I can't see any packets. Anyone an Idea ? -- View this message in context: http://www.nabble.com/802.11-BBN-in-SuSE-tf3977436... Sent from the GnuRadio mailing list archive at Nabble.com.

I am pretty sure we did this under some kind of Linux, and I think it was SuSE. > Failed to set Tx frequency to 2.4G " We didn't have any MIMO cards, so you may be simply hitting a minor bug. > I also tried to capture packets, using ./bbn_80211b_rx.py -d 8 -f 2412e6 -p > , however I can't see any packets. 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.
