Hi Johannes,
What documentation was possible to find? Was this part of it:
http://gnuradio.org/redmine/wiki/gnuradio/TutorialsWritePythonApplications#Controlling-flow-graphs
Anyway, I have attached a slightly modified dial_tone.py which runs
for 5 seconds, then replaces one tone with noise then runs for 5 more
seconds. As for how to trigger it, that depends entirely on the
context, but the reconf method can be called by timeout, user
interaction, external signal, ....
As far as I know you can disconnect and reconnect at any level, and
even hier_block has lock and unlock methods, but I don't know if it
makes sense to lock a flow graph anywhere else than at the top block
level.
