I think a lot of people here would appreciate if you could disclose the bluetooth commands the Ronin-M supports. If you are one of these, please post here to show your interest.

Especially if the commands would include absolute position commands like "look 10° left from center and 30° downwards from horizontal", I guess the demand for this gimbal would spike.

This would enable use to write various apps, so you can control the gimbal movements from a tablet, most importantly pre-program movements.

Use cases:

• A CableCam Controller moves the gimbal while driving on the rope in order to point to the same POI all the time but from different angles.
• Preprogram a movement to repeat the same multiple times, e.g. for a stationary rig or for overlays.
• Timelapse, where you want to pan the gimbal by 180° in 10 minutes.
• Tracking of an object.
• Gigapixel Panoramas
• Ronin is on a crane and depending on the pan of the crane, the tilt is adjusted by the app automatically to ease up the Follow operation - just one axis needs to be controlled manually.
• Simple Astro-Tracking applications.
  

All of that can be enabled at once if only the firmware would support that - if it doesn't already - and you explain how to connect to the bluetooth module executing such commands.
A whole new world of opportunities and use cases for the Ronin at virtually no costs.

DJI deliberately hides the protocol
in order to sell their additional devices, mediocre quality, the only way is a bluetooth sniffer

I am very ashamed of the greed of DJI, now she only cares about money !
