Thanks for the reply Michael. I will look into that as you have advised. So all you say is I need to change and play with the sampling rates and --tx-amplitude  until the received packet becomes 'n_rcvd=1' and CRC check changes to 'ok=true' from the narrowband folder?

Regards,

Hi Dave - I'm thinking that you are confusing "--samples-per-symbol" for the sample rate. I think the option you're looking for is "-r". Look at the "--help" for those examples when you get a chance. - MLD

Thank you very much Michael. I will follow up on your advice. I am sorry that I wasn't able to understand some parts in GNU RADIO and didn't specify enough information.  Regarding the question, I have been doing the benchmark in the digital/ narrowband/ folder. The exact commands I have been working on are

Sender: benchmark_tx.py -f 2.435G --tx-gain 25 --samples-per-symbol 250000

Receiver: benchmark_rx.py -f 2.435G

When I give 250kS/s, my laptop freezes. USRP is XCVR2450. So I started to give less Samples like 50kS/s so that they communicate with each other without errors. But I couldn't figure out the solution to that. So I just have a doubt whether I need to modify benchmark scripts or is it enough for the parameters I give in the command line. Thanks for the help. Please advice
