[Discuss-gnuradio] Flowgraph Control

[Richard Bell]

Hi all,

I'd like a recommendation on how to setup an experiment. I have a full loopback transceiver simulation that I want to test. It contains forward error correction and the full synchronization chain along with AGCs and the like.

For the experiment, I want to set the noise to a value and run the flow graph until I generate enough errors. At that point, I want to reset all the memory elements to default state and change the noise added and run until I generate enough errors again. I keep doing this N times.

In my reading, it seems that start() and stop() are more meant for situations where you are disconnecting/connecting blocks. Is this true or should I consider calling start and stop between each run?

If start and stop is in fact not the way to go, how do I make sure the simulation is put back in the default state. I don't want the control loops of the synchronizers to have any memory of the previous run.

Is there example code that implements something similar to this already?

Thanks,

Rich
