BluetoothAdapter (Firefox OS)

This API is available on Firefox OS for internal applications only.

The BluetoothAdapter interface of the Web Bluetooth API is used to handle all the operations requested by Bluetooth networks. A Bluetooth adapter is the physical interface which is used to interact with local Bluetooth device.

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. 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

A handler for the attributechanged event; it is triggered when one of the local bluetooth adapter's properties has changed
A handler for the devicepaired event; it is triggered when a remote device gets paired with the local bluetooth adapter.
A handler for the deviceunpaired event; it is triggered when a remote device gets unpaired from the local bluetooth adapter.
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

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