Vibration Config

Defines vibration patterns and the duration of the haptic pulse used for touch feedback.

Key path: devcfg.vibr

{
  "devcfg": {
    "vibr": {
      "song": "V10S10V20S10V30",
      "hapticDurMS": 100
    }
  }
}

Important To play a vibration pattern immediately, send an action — do not use devcfg. See Vibr action. Setting song here only changes the default pattern played on the next alert; it does not vibrate the device itself.

song

Vibration song string. A sequence of V (vibrate) and S (silence) tokens, each followed by a duration in units of 100 ms.

Configuration variables

• Type: string
• Default: "V10S10V20S10V30"

Token	Meaning
V + number	Vibrate for number × 100 ms
S + number	Silence for number × 100 ms

{ "devcfg": { "vibr": { "song": "V20S5V20" } } }

hapticDurMS

Duration of the haptic vibration when a touch button is pressed. Set to 0 to disable touch haptics.
