Step by step

In the project file, put these settings first:

...
CONFIG += mobility
MOBILITY += feedback
...

Next step, I'll put some of these code below to main.qml file

import QtMobility.feedback 1.1
 
PageStackWindow {
    id: appWindow
 
    HapticsEffect {
        id: rumbleEffect
        attackIntensity: 0.0
        attackTime: 250
        intensity: 1.0
        duration: 250 // set up the duration here, in millisecond
        fadeTime: 250
        fadeIntensity: 0.0
    }
}

Ok, now wherever you want to start the vibration, just easily call the rumbleEffect

...
appWindow.rumbleEffect.start();
...
