I've written a python script that instantiates a top_block.py file (no
GUI), sets the parameters, runs until 100 block errors are detected, stops
the simulation and starts the process over with a new instantiation, etc..
The problem I have is that I randomly (as far as I can tell) have a problem
where the gnuradio simulation stalls out during one of these simulations.
Everything its supposed to be printing to terminal stops. I can still hit
'Ctrl-C' to get it to move on to the next simulation, and it will continue
on working after that. But I can't figure out why it stalls such that all I
can do to get it to move onto the next simulation iteration is hit 'Ctrl-C'.
For an example of what I mean by stall, I added a message debug block to my
sim just to see if that also stopped outputting to terminal when the stall
happened, and sure enough, it too was effected.
I can't recreate this issue when I just the radio from GRC. It always runs
fine.
Has anyone experienced something like this when using python? What I do in
python is pretty simple:
for nn in xrange(0,nsims):
tb = top_block()
time.sleep(1)
--set a bunch of radio paramters--
tb.start()
tb.wait()
tb.stop()
--collect results and push to file--
tb = None
I could really use some debug help
