Benchmark_ofdm_rx not working


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

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

./ -f2.4e9 -R A (at the other USRP connected to

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

However the script does not give any output. I
think the rx_callback function is being executed(as the packets are
in that function).

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

Thank you.

Thank you.

First, try running the benchmark_ofdm_tx on one side and tht usrp_fft to
display the received power at the receiver. What does this look like?

The problem is likely that you are not transmitting enough power. There
is a --tx-amplitude flag to adjust this. Set it to 2000 - 4000.
