I try to run the fm transmitter example in the gnu example directory
I got the error like
"AttributeError: 'db_basic_tx' object has no attribute 'which'"
I gave the following command,

OK. Finally managed to get the gnuradio compiled and installed. Now I've
put the recommended 10-usrp.rules file in the right place, checking the
syntax twice, and tried all the suggested steps (reboot, start/stop udev,
killall etc.). When I look at /dev/bus/usb, I see the "owners" of the

Thanks for pointing out the problem. But doesn't the FX2 firmware download
automatically? Isn't it a part of the USRP's boot sequence? How can I load
the firmware then to get rid of this problem?

It was a firmware problem, and after updating the latest firmware I was able
to transmit/receive at 1Mbps.

Good work everyone! =)

Hi,
I am unable to replicate the results. Are you using the code from the CGRAN
repo without any modifcations?
I am also receiving a "usrp2::ctor reset_db failed" error. Could this be a
problem?
Thanks,
Colby

Hi,
I don't have two usprp2. So I am trying to communicate between usrp1 and
usrp2. Moreover, in the transmit_path.py file I have hard coded my usrp2's
mac address so you would have to replace it with yours before using it. If
there are any other problems with the code then please let me know

Yep!
It works also here between USRPs2 with the code from colby's branch (also with
other parameters, as far as interp*spb=~200).
The problem is the DSSS... I don't know why, but whenever Barker is enabled,
nothing works anymore... :-(
Have you tried?

The script you are trying to run was written for GNU Radio 3.1 or
earlier. That module no longer exists in 3.2 or the development
trunk; it's functionality has been incorporated into the 'usrp'
module.

If I recall well it is a 100 pF 603 capacitor.

Good News
I finally succeeded to receive with an USRP2 packets sent with another
USRP2. I tryed to modify the parameters and found the magic combination:

Hi
I don't yet know a lot about the USRP, but I do know about USB.
The short answer is that the PIC 18F4550 processor will not help.

packet and a "device" to talk to. Optionally a hub is both a device

I ran the test script with the barker code as the TX/RX filter and I am
unable to decode packets. When the SPB is set to 2, I can decode some of the
packets. You have to set the use of barker codes manually in the test
script.
Has anyone else encountered this problem?
Thanks,
