Re: [Discuss-gnuradio] python Hier block using callback

[Marcus Müller]

the point is that if the print is not appearing, then the callback isn't
working as you expect. You should really make sure to use the right
variable names.
You're not really sharing all the interesting information; it's a bit
hard to figure this out in what's becoming a dialogue.
I'd like to ask you to read

Best regards,
Marcus
