Hi Guy,
you don#t have to stop a flow graph to set the gain value. In fact, you
shouldn't.
Yes, you'll still have signal passing through your USRP while you're
adjusting the gain, but that's exactly what timed commands are for.

Just call set_gain() from the thread context of the USRP sink, i.e., the
top_block. Use a semaphore: the thread doing the calling sets a semaphore
in the top_block, and then the top_block runs a loop which looks for that
semaphore to be set and then calls set_gain.

Hello,
I'm currently working on a multithreaded application which needs to set the
gain value of a USRP sink at runtime. The only thing I've found that works
so far is:
stop() -> wait() -> lock() -> set_gain() -> unlock() -> start()
I tried using just lock/unlock, but this causes the SDR to free
