Re: [Discuss-gnuradio] Fwd: Re: Transmission error

[Rama V]

Do I need to use gnuradio - companion for transmission and reception of the data packets or the benchmark_tx.py commands from the terminal would be enough for that to happen. I am unable to sort out. Kindly help.

Regards,
Dave

Hey all,

I have a small doubt regarding the reception of data packets. I am attaching a small figure of the command 'uhd_fft' where I mentioned the frequency and the sampling rate as 250k. The command I have given for this  was

./benchmark_tx.py -m qpsk -M 2 --discontinuous -f 2.435G

I tried to run this and I see an 'U' in the middle of transmission. Is this why I was not able to receive the packets because I get

ok = False pktno = 53034 n_rcvd = 1 n_right = 0

My PC is Dell Inspiron 15R 5537 and I think it's somewhat a new version. Do I need to mention any sample rate in the command of benchmark. And also when I set the sample rate to 250k in my benchmark command, my laptop freezes and I need to restart it again. Do I need to give a low value? Please help and excuse for my brevity.

Thanks,

Dave
