Hi everyone, now I have one a USRP device with two RFX 2400. when i try
to
use the example in
gnuradio-example/python/ofdm/ benchmark_tx/rx.py. i use this one board
to
send and receive.
the following command is the command i use, but the result is Timeout.

I can not figure that out, anybody can give me a idea~, the gnuradio is
Version3.2. is the problem of the gnuradio daughterboard or i use the
wrong
command. i just use the example in the gnuradio. what can i do, thnx~.
./benchmark_tx.py -m qpsk -f 2400M --tx-amplitude=5000 -T A --log
./benchmark_rx.py -m qpsk -f 2400M -R A --log

suggest you open the “logging” flag, then have a look at the data file
to
find which block doesn’t work well.
