Hello,
I am trying to reconfigure a flow graph based on a signal. The signal handler does a stop on a flow graph but the routine that is running the flow graph and waiting on the top block, never returns from the wait on the top block of the flow graph. I am using osmosdr + gnuradio even though the signal handler stops flow graph using tb.stop().
I am not sure if this is relevant but, strangely, this only happens when I am using a USRP as a source. When I use bladerf with the same code it works the way I intended (in both situations, I am using osmosdr). Do I need to do something to make stop() work as intended?
Thanks in advance for any clues.
