Properties

BluetoothAdapter.address Read only: A string representing the address of the device's adapter.
BluetoothAdapter.discoverable Read only: A boolean indicating if the device is discoverable (true) or not (false) by other Bluetooth devices.
BluetoothAdapter.discovering Read only: A boolean indicating if the device's adapter is in the process of discovering (true) or not (false) surrounding Bluetooth devices.
BluetoothAdapter.gattServer Read only: Returns the BluetoothGattServer to use to conduct GATT server operations on the local bluetooth adapter. Will return null if the adapter is not enabled.
BluetoothAdapter.name Read only: A string indicating the human readable name of the device's adapter.
BluetoothAdapter.pairingReqs Read only: Returns the BluetoothPairingListener object containing the event handlers needed to response to different pairing types operations.
BluetoothAdapter.state Read only: Returns the state of the local bluetooth adapter.

Event Handlers

BluetoothAdapter.onattributechanged: A handler for the attributechanged event; it is triggered when one of the local bluetooth adapter's properties has changed
BluetoothAdapter.ondevicepaired: A handler for the devicepaired event; it is triggered when a remote device gets paired with the local bluetooth adapter.
BluetoothAdapter.ondeviceunpaired: A handler for the deviceunpaired event; it is triggered when a remote device gets unpaired from the local bluetooth adapter.
BluetoothAdapter.onpairingaborted: A handler for the pairingaborted event; it is triggered when pairing fails due to authentication failure, the remote device being down (bluetooth ACL becomes disconnected), or some kind of internal error.

Note: Because the BluetoothAdapter interface inherits from the EventTarget interface, all these events can be listened by using the addEventListener method.

Obsolete properties

BluetoothAdapter.class Read only: A number representing the Class of Device(CoD) field of the device's adapter.
BluetoothAdapter.discoverableTimeout Read only: A number indicating how long (in seconds) the device remains discoverable.
BluetoothAdapter.devices Read only: An Array of BluetoothDevice object representing all the Bluetooth devices discovered in the area surrounding the device.
BluetoothAdapter.uuids Read only: An Array of string, each of them representing the UUID of a Bluetooth service the device's adapter is able to provide.

Obsolete event handlers

BluetoothAdapter.ona2dpstatuschanged: A handler for the a2dpstatuschanged event; it is triggered when an A2DP connection status changes.
BluetoothAdapter.ondevicefound: A handler for the devicefound event; it is triggered when a Bluetooth device is found.
BluetoothAdapter.onhfpstatuschanged: A handler for the hfpstatuschanged event; it is triggered when an HFP connection status changes.
BluetoothAdapter.onpairedstatuschanged: A handler for the pairedstatuschanged event; it is triggered when a pairing process is completed.
BluetoothAdapter.onrequestmediaplaystatus: A handler for the requestmediaplaystatus event; it is triggered when a remote Bluetooth device queries the current media play status.
BluetoothAdapter.onscostatuschanged: A handler for the scostatuschanged event; it is triggered when a SCO connection status changes.
