Re: [Discuss-gnuradio] GRC: Reference a Block from Other Block

[Johannes Demel]

Hi Gilad,

it is possible to pass references to other blocks to your custom block. 
But you should avoid this implementation. First off, another block is 
scheduled in another thread. This might cause runtime issues.

If you need status information from another block, add a message port 
that outputs this information. Make it useful to everyone and upstream 
your additional functionality.

If you want to update the internal status of another block. Definitely 
use message ports to set internal variables.

Cheers
Johannes
