[Discuss-gnuradio] problem in executing benchmark_tx.py

Hi,

 

I am trying to run benchmark_tx.py with USRP1 from one PC, and receiving data with another USRP1 from another PC, with this some .dat files are getting generated with some junk data.

My approach:

At TX PC:  ./benchmark_tx.py --modulation=gmsk --size=1500 --megabytes=1.0 --from-file=payload.dat --freq=423e6 --bitrate=500000 --tx-subdev-spec=A --tx-amplitude=12000

 

At RX PC:  ./benchmark_rx.py --modulation=gmsk --freq=423e6 --bitrate=500000 --rx-subdev-spec=A

 

Can anyone tell me what is wrong in my approach, (why junk data is getting written) and how to resolve this issue.

 

Thanks,

Ashwini
