Hi here is my idea:
I want to control BBZ351 - Bluetooth Helicopter. With accelerometer in watch. So you will be albe to control helicopter by motion of your hand.
Simplest solution is just up and down motion to accelerate and decelerate rotor.
So here is some struggles:
Bluetooth in watch will not be compatible because it´s BLE bluetooth low energy in helicopter is bluetooth chip 3.0, class 2. And I found it´s not compatible. It will not be connected directly, (watch - helicopter), instead another android app must be developed. Wich will provide data from watch and transfer them to helicopter. Because most of smart phones have both capability BLE and bluetooth 3.0. It will be (Watch - smart phone - helicopter)
Here is link to helicopter manufacturer:

Any ideas how to figure it out ?
