How to consolidate mavlink instances

1

I’m facing some memory issues with the Black Cube (FMUv3) and could use some advice from the experts. Currently we have 3 mavlink instances running (Radio telemetry, Companion Computer, and a Payload).

Is this architecture way off base? Each mavlink instances takes a huge amount of memory relative to the other modules.

Is there a way to bind a single mavlink instance to multiple ports? Would it be feasible to modify the mavlink code to allow this and save on the overhead that each individual mavlink instance is creating?

From Slack it sounds like protocol_splitter is what I’m looking for.

Ok, it seems protocol splitter is kind of the opposite thing I need - it binds a single serial port to two virtual devices /dev/mavlink and /dev/rtps.

Hi, did you manage to handle it through the set parameter setup?

Nope. Had to just get rid of a mavlink instance and limit myself to 2.
