The first thing that comes to mind is to use threads and a join with a

You would implement this in benchmark_rx.py.

But how would i come to know in the benchmark_rx.py whether the data is being received or not.
As far as i see, this is being done at tb.wait

Let me rephrase. When benchmark_rx.py is run, lets say initially there is no transmission being carried out, so benchmark_rx.py waits for transmission. I would like to know where is this happening in the code? tb.wait() is called, but i don't see the code in wait() function which actually senses if a transmission is being carried out on the specified frequence or not? Can someone please help me locate the transmission sensing code in benchmark_rx.py?

 

Thanks
