No, that message is just te
Hi Tom,
In our case, even with script from Veljko, the OFDM receiver doesn't show
any thing. And we always see "usrp2: failed to enable realtime scheduling".
Do you think that will cause problem?
Thanks,

Hi Tom ,
Thanks , we did try the updated script from Veljko . It works though we have
missing packets after a while ( as suggested in the forum we would play with
the interpolation and decimation ) though the 2 USRP2s are directly
connected .
We are still probing into the permissions issue as ind

Hi,
We did try the below command on two USRP2s coneected via a SMA Cable
(Tx-Rx)
with freq = 25M however it returned the following error on both sides
At Rx side it shows like the below -
[r...@gnuradio1 ofdm]# ./benchmark_ofdm_rx.py -f 25M -d 256
--fft-l
Hi,
We did try the below command on two USRP2s coneected via a SMA Cable (Tx-Rx)
with freq = 25M however it returned the following error on both sides
At Rx side it shows like the below -
[r...@gnuradio1 ofdm]# ./benchmark_ofdm_rx.py -f 25M -d 256 --fft-length=64
--occupied-tones=32 --cp-lengt
Thanks Veljko, Did you do any modification on the gnuradio 3.2.2 code?
(Because at my side the interpolation/decimation was not the problem, I
forgot to change the value in the email)

Hi,
I have gnuradio 3.2.2 installed on Ubintu 9.10 and I'm using USRP2s
with XCVR2450 daughterboards.
I tried your example but I changed the interpolation to correspond to
the decimation at the receiver:
./benchmark_ofdm_tx.py -f 2.4G -i 256 --fft-length=64
--occupied-tones=32 --cp-length=4
./ben
Hello,
I was trying to run following OFDM command on USRP2, however, I got a
bunch of "Stime out" at the receiver side.
./benchmark_ofdm_tx.py -f 2.4G -i 512 --fft-length=64 --occupied-tones=32
--cp-length=4
./benchmark_ofdm_rx.py -f 2.4G -d 256 --fft-length=64 --occupied-tones=32
--cp-
