Timer

The timer module, MBLTimer, allows you to create periodic events that trigger a certain number of times.

Periodic Event

Here is a simple way to buzz 3 times.

let periodicEvent = device.timer?.event(withPeriod: 2000, eventCount: 3)
periodicEvent?.programCommandsToRunOnEventAsync {
    device.hapticBuzzer?.startBuzzerAsync(pulseWidth: 500, completion: nil)
}
