Is it possible to communicate between internal control functions

[johekb]

I have a use case where I want to register two internal control functions in the same executable. From what I can see it is no problem to register them both on the network using address claim. But when I want to send a broadcast message I can see that the message goes out on the bus but I don't get any callbacks back to my other control function. Is this a valid use case?

Currently internal control functions do not receive messages from other internal control functions. Mostly this was a choice we made during development of the CAN stack because there are far more efficient ways to communicate within the same process that aren't 8 byte CAN, frames haha.

It would be possible I think for us to allow this kind of thing to work, but I think you might be the first person to ask about it.

What is your use case like/why are you interested in doing that? I am curious

Yes, I agree that it is much more efficient to communicate in other ways but what I was actually thinking of was when sending a broadcast message I guess all participants should react on the same data. If having a separate channel for internal functions I need to handle two communication channels so to speak.
