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

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 value 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.
