[Discuss-gnuradio] running multiple flow graphs simultaneously

[Rob Miller]

Hi -

Is it possible to run more than one top_block at a time in gnuradio 3.7.x?  I have an application where I wish to run an additional flow graph periodically.  I have set up a thread that grabs samples via a probe from my main flow graph that is running all of the time, and uses that data to source another flow graph.  Everything appears to be running, however I want to be certain that I'm not doing something terribly wrong --- especially since two relevant sources of information seem to contradict my current mode of operation:
