How to get my touch controllers to vibrate?

[psychoVR]

I’m trying to get my touch controllers to vibrate. I’ve tried with OVRPlugin.setcontrollervibration but have had no luck. Has anyone succeeded in getting their controllers to vibrate?

After looking around and try to understand what i was reading I finaly got it to work and wrote a simple demo to see if I understod it correctly. Here it is.

using UnityEngine;

public class TeleportScript : MonoBehaviour {

    //Audio input used for vibrate left controller
    public AudioClip AC;

    // used to make a saw wave 
    private int wave = 0;
        	
	// Update is called once per frame
	void Update () {

        //checks if any button is pressed on the touch controllers
        OVRInput.Update();

        //Left hand controller index button
        if(OVRInput.Get(OVRInput.Axis1D.PrimaryIndexTrigger,OVRInput.Controller.Touch) > 0f) {
            //outputs vibration to left controller
            OVRHaptics.Channels[0].Preempt(new OVRHapticsClip(AC));
        }

        //Right hand controller index button
        if (OVRInput.Get(OVRInput.Axis1D.SecondaryIndexTrigger, OVRInput.Controller.Touch) > 0f) {
            
            //the value determens the power of the vibration
            //scale from 0 to 255 
            byte[] noize = { 255 };
            // tho 40 was about when I coulde start feel it
            //byte[] noize = { 40};

            //outputs vibration to left controller
            OVRHaptics.Channels[1].Preempt(new OVRHapticsClip(noize, 1));
        }

        //right hand trigger button
        if (OVRInput.Get(OVRInput.Axis1D.SecondaryHandTrigger, OVRInput.Controller.Touch) > 0f) {
            //make a saw wave 
            wave++;

            if (wave >= 255) {
                wave = 0;
            }

            byte[] noize = { (byte)wave };

            //outputs vibration to left controller
            OVRHaptics.Channels[1].Preempt(new OVRHapticsClip(noize, 1));
        }

        //this updates the controlls
        OVRHaptics.Process();
    }
}

On the left controler I used a audiofile wich was a 30 sec long sin wave and the controller woulde vibrate untill the hole clip has been played tru.
