[Discuss-gnuradio] benchmark_ofdm_rx not working

[Archana Ragothaman]

Hello,

I am using two USRPs rev 4 and two RFX2400. I am basically trying to make the USRPs communicate with each other using the benchmark_ofdm_tx.py and benchmark_ofdm_rx.py scripts. The commands I am executing are

./benchmark_ofdm_tx.py -f2.4e9 -T A (at one USRP connected to laptop)

./benchmark_ofdm_rx.py -f2.4e9 -R A (at the other USRP connected to another laptop)

The benchmark_ofdm_tx.py script is working as I can see the packet number displayed(I wrote a print pktno in the script)

However the benchmark_ofdm_rx.py script does not give any output. I don't think the rx_callback function is being executed(as the packets are printed in that function). 

Can anyone please help me out and give suggestions as to what the problem could be?

Thank you.

Dominik-

You may have already heard privately from Eric, but yes, we'd like to
see your code for review and possible incorporation into the project.

Is it published anywhere else?

All of the host code in GNU Radio is copyrighted by FSF, so if we do
incorporate it, there is a copyright assignment process you'll have to
go through.

Thanks for offering it.  While we already have an in-progress OFDM
implementation, having multiple options is good, and it may even be
possible to merge implementations.
