Hi,
I am working on a cognitive radio system. the transmitter side senses the
spectrum and then transmits on a carrier frequency which it finds free.
The receiver should be kept synchronized with the transmitter. The
transmitter is for now tx_voice.py and receiver is rx_voice.py.

Hi,
As far as I could understand, rx_callback function in benchmark_rx.py
executes only when a packet is received.
If the tranmitted freq is 460e6 while the reciever is set at 459e6, no
packet would be received. I want this 'no packet being received for a
certain amount of time' as an indication
