I had successfully transmit data without any problems using
benchmark_tx/benchmark_rx moment ago:
./benchmark_rx.py -f 2.42G -r 2M
./benchmkar_tx.py -f 2.42G -r 2M
But after a few tries, the rx end started to show 0000… The wired
thing
is that I input the same parameters as before but the result is
different:
bell@bell-HP-Compaq-4000-Pro-SFF-PC:~/Desktop/USRP/gnuradio/gr-digital/end$
./benchmark_rx.py -f 2.47G -r 2M
