Is there any way to control pan/tilt/roll angles via script running on Linux (eg Raspberry Pi)? I see there are a few posts covering the RS2 via the CAN port on the NATO rail on the side. Best I can tell the RS3 does not have that CAN port. The USB-C charging port on the grip seems not to have any data function, so I guess the only way in is via the Bluetooth interface.
I notice that I have access to a virtual joystick from the Ronin Android DJI app. Is that Bluetooth protocol documented anywhere?

(Note: I'm referring to the regular RS3, not the pro edition).

Any DJI engineers here any more? It would be good know if this is possible or not. I have an application for it which would result in quite a few purchases of the product if it worked out.
