Can I use SITL to simulate FC with APSync on RaspPi?

I’ve installed APSync on a RaspPi but can’t test it works as I don’t currently have a flight controller. Does anybody know if SITL will allow me to successfully simulate a flight controller and allow APSync to connect with mission planner on my ground station laptop?
I’d like to know if its likely to work prior to installing SITL on my RaspPi.

Should be doable. We provide SITL binaries on
which should be suitable. Past that you would have to configure whichever
telemetry agent you’re running (mavlink-router, perhaps?) to connect to
the SITL binary once it is running (in the same way that MAVProxy does).
