I have tried the following commands in the terminal Sender : benchmark_tx.py -f 2.435G -r 250k Receiver : benchmark_rx.py -f 2.435G
But the data packets are not being sent correctly. I have been receiving the packets as ok=false. I have tried modifying benchmark python scripts. Can I do the modification of those scripts or evrything needs to be given in the command line. Please excuse me as I am slightly unable to understand.
