[Discuss-gnuradio] callbacks from gr block into python for reconfiguration

[Jorg Lotze]

Hi,

I would like to know if it is possible with GNU Radio to have callbacks
from a processing block into python to trigger a reconfiguration. A
possible scenario is a radio which changes its receiver frequency when a
the signal was lost (due to a change in the transmitter frequency). For
example, if no frames are detected within a certain window, the deframer
should be able to notify Python that this has happened, so that the
appropriate reconfigurations can be performed.

What would be the way to do this in GNU Radio?

Thanks,
Jorg
