I was lucky enough to pick up a P2 with a zenmeuse gimbal and decided to try it, and sure enough it works, albeit with a few small issues.
You cant use an IOS device, well to be precise you can but you wont, for some unknown reason, get Telemetry data (works fine on Android) and you can't enable recording from the app.
You can still use Litchi, Ultimate Flight app as well as the original DJI Vision app.
