I urgently need to access to touch controllers battery level from Unity, i know it's available somewhere because we can see the battery level in the Oculus Software, but I tried several ways and no method works:
1) In Unity, use Oculus Utilities asset's OVRInput.GetControllerBatteryPercentRemaining() method: It returns 0 and the method's summary says "Retuns the battery percentage remaining for the specified controller. Values range from 0 to 100. Only applicable to controllers that report battery level, such as the GearVR Controller. Returns 0 for controllers that do not report battery level" so i concluded that Touch Controllers don't report battery level to OVRInput. This person has the same problem : https://forums.oculusvr.com/developer/discussion/69979/oculus-go-get-controller-battery-level and Oculus given no answer.
