we are trying to get run the tunnel.py / benchmark_rx.py (OFDM) in order
measure the datarate between two USRP2 (located with distance of 1 m)
We are running the benchmark_tx/rx.py as follows:
benchmark_tx.py -f 2.4G --tx-gain=10 --tx-amplitude=0.8 -v
benchmark_rx.py -f 2.4G --rx-gain=4 -v
We already tried to tune the parameters by analyzing the spectrum by
gnuradio-companion. It looks reasonable and the SNR is round about 20 dB
which should be fine?
Unfortunately, we don’t get any packets transmitted. The RX side always
Our configuration is as follows:
- Ubuntu 10.04
- gnuradio 3.5.1 (installed freshly)
- UHD firmware version 003.003.001
Has anybody already got the tunnel.py/benchmark_tx.py run with a similar
configuration? Has anybody an idea what we are doing wrong?
Thanks in advance for your help! Best Regards, Florian
