Please be aware that the ring controller joystick is limited. So far I have been unable to determine how to obtain ‘analog joystick’ values out of the ring controller joystick. If I could figure this out over the BLE interface I would do it but I lack documents to help me get ‘analog’ joystick values from this device and extensive experimentation has not yielded the answer as well. This little joystick that fits on a finger does full on or full off control and then the A and C buttons increment or decrement the speed being used respectively. There is little to no documentation I have been able to find to help pull out analog values from this ring controller so it is limited at this time to crude motor control and not fine grain control such as we support with the LogiTech F710 game controller joystick.
