hello everyone,
I 'm trying to collect some samples from my spectrum sensing code running on
USRP2, which is a slightly revised version of 'usrp_spectrum_sense.py'. My
problem is that after some time during the scan of some band, this message
appears: "Failed to set frequency to ...". For instance

I checked and they're not hundreds. In fact there does not seem to be
anything unusual about that.
Plus I see some 'S' sequences every 3 or 4 failed scans too. In USRP2 usage
FAQ, it says this happens when packets are dropped. But I don't know which
one causes the other one.

Yes that's correct. It always works fine at the start.

Hi Smith,
Did you manage to receive with USRP2? I'm kinda stuck with the same problem
(Tx/Rx with 2 USRP2s). 'bbn_80211b_rx' does not receive what I'm
transmitting with 'bbn_80211b_tx'.
Thanks,
Rahman

Guys,
I'm working on the same thing, I'm trying to receive something with OFDM
example, USRP2 and XCVR boards. But it doesn't work. The transmitter is
sending and the rx signal is crystal clear with spectrum analyzer but no
packet is caught.
Could anyone of you send me the command you're using at
bandwidth of the receiver to allow for the frequency

Hi,
Has anyone tried to run Simulink USRP2 examples and succeeded to send or
receive signal to/from USRP2? The demos work for loopback but not when I
change the IP address input of the USRP2 (Simulink) block to my USRP2 actual
IP address which is default 192.168.10.2
I have installed libuhd, updat
system and
some code is publicly available.
Cheers,
Rahman Doost

d, or representing
the currect frequency sub-band which is being scanned. I was wondering If
someone can help me out on this.
