Exposing packet informatoin

I wrote a VITA-49 deserializer block. How can I expose information like
the sample rate extracted from the header to the other blocks in the
system?

Hi ?arc,

This depends on the other blocks you’re looking at!
The gr-uhd USRP source uses stream tags to enrich the sample stream with
such information as rx_freq and rx_time, but the other blocks need to
care about these tags, or they won’t change their behaviour.

That is what you would use stream tags for.

Cheers,
