This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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


interface Bluetooth : EventTarget {
  [SecureContext] Promise<boolean> getAvailability();
  [SecureContext] attribute EventHandler onavailabilitychanged;
  [SecureContext, SameObject] readonly attribute BluetoothDevice? referringDevice;
  [SecureContext] Promise<BluetoothDevice> requestDevice(optional RequestDeviceOptions options);
Bluetooth implements BluetoothDeviceEventHandlers;
Bluetooth implements CharacteristicEventHandlers;
Bluetooth implements ServiceEventHandlers;


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.


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


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.
Returns a Promise to a BluetoothDevice object with the specified options.
