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

[Gilad Beeri (ApolloShield)]

The method I want to call is thread-safe, and the target block doesn't support the required message.

Regardless, I only need it for quick prototyping so I don't care at this stage if this is clean or not. This is an experimental GRC flowgraph for me.

How do you pass a reference to the target block, or to the top block, from GRC GUI, to my custom block?

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
