Oh, my problem is the same with yours: I want to change transmit frequency according to the sensing result from rx side. I tried lock() and unlock() but cannot work.
I solved it by creating 2 flow graphs for tx (to transmit files) and rx (to sense the channel) sides separately and call start(), wait(), stop() of theirs orderly.
This is a dumb solution (pretty dumb actually), but maybe it could your reference, so I write this down to you.

Hello Yang,
Do you have any specific questions?
Better you write some example programs first, then come back with your
exact questions I think.
