Overview

The BluetoothManager API allows to access all bluetooth adapters available on the device. Adapters are the interfaces that connect to the remote device.

Interface

interface BluetoothManager: EventTarget
{
  attribute EventHandler onadapteradded;
  attribute EventHandler onadapterremoved;

  any              getAdapters(); // array of BluetoothAdapter
  BluetoothAdapter getDefaultAdapter();
};

Event Handlers

onadapteradded

Description
A handler to trigger when a bluetooth adapter is plugged into the device. The event carries evt.adapter as the plugged BluetoothAdapter. Applications should call getDefaultAdapter() in this event handler to retrieve the current default adapter if there is no adapter plugged in, suggest to call getAdapters() for the most updated array of adapters on the device.
Sample
function bt_onAdapterAdded(evt) {
  var adapter = evt.adapter;
  // do your thing here!
}

var manager = navigator.mozBluetooth;
manager.onadapteradded = bt_onAdapterAdded;

onadapterremoved

Description
A handler to trigger when a bluetooth adapter is unplugged from the device. The event carries evt.address as the address of unplugged BluetoothAdapter. The unplugged BluetoothAdapter object is already unavailable and access to its attributes returns default values. Applications should call getDefaultAdapter() in this event handler to retrieve the latest default adapter, and may call getAdapters() for the latest array of adapters on the device.
Sample
function bt_onAdapterRemoved(evt) {
  var address = evt.address;
  // do your thing here!
}

var manager = navigator.mozBluetooth;
manager.onadapterremoved = bt_onAdapterRemoved;

Methods

var adapters = manager.getAdapters();

getDefaultAdapter()

Description
The getDefaultAdapter method retrieves the default adapter used to connect to the remote bluetooth devices.

The default BluetoothAdapter object.
