the USRP2 was blown. Its rather
easy to replace once you identified it as the problem.

If I try uhd_find_device no device is found.
The firmware and the FPGA image on the SD card is working fine.

Hey Josh,
thanks a lot. Now it works.
I'll try to implement algorithms soon.
But this should be a first step.

Hello list,
I would like to announce support for the MIMO cable with UHD. The
support is experimental, so its not in the mainline yet, and is on
f the FPGA at the moment.
So I guess I have to wait for the release of the new FPGA images for UHD, do I?
Or did you already release the new UHD image?
Thanks Tobias

I implemented a selective repeat ARQ-protocol using the USRP2.

Hi,
I found the appended THread in the archive.
That time, there was no answer to this mail.
But I have exactly the same problem to understand the architecture of

It would be nice, if anyone could write a short explanation why the \x55

message sink to get the whole coded sequence and hand it over as a
payload for the ofdm_mod.
So me next question is, while catching the items in that queue, do I
have to count the incoming bytes or the number of incoming samples?
Thanks for your help

Hello Achilleas,
that's exactly what I thought abaout as well. Because the part I
discribed as channel in my last mail is a wireless transmission using usrp2.
Not using channel coding, I have packet error rates of 1 to 2 % using
bpsk subcarrier constellation and abaout 18 % using qpsk. And if
ontrol signal that tells you where the
frame starts, which flows on the other ofdm_recv port?
Cheers,
Veljko

correctly. Try
# route add -net 192.168.10.0/24 <http://192.168.10.0/24> dev eth1
or check
# route -n
to see if the routing is using the proper network devices.

Hi,
I've got exactly the same problem.
In my case the lights D and F are light up.
The usrp2_card_burner_gui.py works correctly. I've checked that by
flashing the cards with the common firmware.
And that works fine.
