Experimental

The Bluetooth interface of the Web Bluetooth API returns a Promise to a BluetoothDevice object with the specified options.

Interface

interface Bluetooth : EventTarget {
  Promise<boolean> getAvailability();
  attribute EventHandler onavailabilitychanged;
  [SameObject]
  readonly attribute BluetoothDevice? referringDevice;
  Promise<sequence<BluetoothDevice>> getDevices();
  Promise<BluetoothDevice> requestDevice(optional RequestDeviceOptions options = {});
};
Bluetooth includes BluetoothDeviceEventHandlers;
Bluetooth includes CharacteristicEventHandlers;
Bluetooth includes ServiceEventHandlers;

Properties

Inherits properties from its parent EventTarget.

Bluetooth.referringDevice Read only: Returns a reference to the device, if any, from which the user opened the current page. For example, an Eddystone beacon might advertise a URL, which the user agent allows the user to open. A BluetoothDevice representing the beacon would be available through navigator.bluetooth.referringDevice.

Events

Bluetooth.onavailabilitychanged: An event handler that runs when an event of type availabilitychanged has fired.

Methods

Bluetooth.getAvailability(): Returns a Promise that resolved to a Boolean indicating whether the user-agent has the ability to support Bluetooth. Some user-agents let the user configure an option that affects what is returned by this value. If this option is set, that is the value returned by this method.
Bluetooth.getDevices(): Returns a Promise that resolved to an array of BluetoothDevices which the origin already obtained permission for via a call to Bluetooth.requestDevice().
Bluetooth.requestDevice(): Returns a Promise to a BluetoothDevice object with the specified options.
