Hey Lou,

That's a very interesting approach, I'll look into your example as well. Thank you very much!

You can also use probes to bring out the data asynchronously from the flow
which you can then process in Python.  For example, you could probe at a 10

some other event.  I have an example here where it probes the signal level
every second and logs it with GPS data:
