Re: [Discuss-gnuradio] how to trigger dynamic reconfiguration with lock/disconnect

[Scott Johnston]

So you have to reach some state that makes you want to reconfigure, e.g. 
you finished scanning some particular band or some time limit is 
reached. Whenever you reach the point that you want to reconfigure, set 
a flag, then check for the flag in your main application.

My typical program flow is

application
top block
hier block

So in the application level is where you want to test for a flag of some 
kind. This is the simplest way that I know of. You can certainly do it 
with threads, but that seems trickier.
