BluetoothManager

public final class BluetoothManager
extends Object

java.lang.Object
↳	android.bluetooth.BluetoothManager

High level manager used to obtain an instance of an BluetoothAdapter and to conduct overall Bluetooth Management.

Use Context.getSystemService(java.lang.String) with Context#BLUETOOTH_SERVICE to create an BluetoothManager, then call getAdapter() to obtain the BluetoothAdapter.

Developer Guides

For more information about using BLUETOOTH, read the Bluetooth developer guide.

Requires the PackageManager#FEATURE_BLUETOOTH feature which can be detected using PackageManager.hasSystemFeature(String).

Public methods

getAdapter

public BluetoothAdapter getAdapter ()

Get the BLUETOOTH Adapter for this device.

Returns
`BluetoothAdapter`	the BLUETOOTH Adapter

getConnectedDevices

public List<BluetoothDevice> getConnectedDevices (int profile)

Get connected devices for the specified profile.

Return the set of devices which are in state BluetoothProfile#STATE_CONNECTED

This is not specific to any application configuration but represents the connection state of Bluetooth for this profile. This can be used by applications like status bar which would just like to know the state of Bluetooth.
Requires Manifest.permission.BLUETOOTH

Parameters
`profile`	`int`: GATT or GATT_SERVER

Returns
`List<BluetoothDevice>`	List of devices. The list will be empty on error.

getConnectionState

public int getConnectionState (BluetoothDevice device, 
                int profile)

Get the current connection state of the profile to the remote device.

This is not specific to any application configuration but represents the connection state of the local Bluetooth adapter for certain profile. This can be used by applications like status bar which would just like to know the state of Bluetooth.
Requires Manifest.permission.BLUETOOTH

Parameters
`device`	`BluetoothDevice`: Remote bluetooth device.
`profile`	`int`: GATT or GATT_SERVER

Returns
`int`	State of the profile connection. One of `BluetoothProfile#STATE_CONNECTED`, `BluetoothProfile#STATE_CONNECTING`, `BluetoothProfile#STATE_DISCONNECTED`, `BluetoothProfile#STATE_DISCONNECTING`

getDevicesMatchingConnectionStates

public List<BluetoothDevice> getDevicesMatchingConnectionStates (int profile, 
                int[] states)

Get a list of devices that match any of the given connection states.

If none of the devices match any of the given states, an empty list will be returned.

This is not specific to any application configuration but represents the connection state of the local Bluetooth adapter for this profile. This can be used by applications like status bar which would just like to know the state of the local adapter.
Requires Manifest.permission.BLUETOOTH

Parameters
`profile`	`int`: GATT or GATT_SERVER
`states`	`int`: Array of states. States can be one of `BluetoothProfile#STATE_CONNECTED`, `BluetoothProfile#STATE_CONNECTING`, `BluetoothProfile#STATE_DISCONNECTED`, `BluetoothProfile#STATE_DISCONNECTING`,

Returns
`List<BluetoothDevice>`	List of devices. The list will be empty on error.

openGattServer

public BluetoothGattServer openGattServer (Context context, 
                BluetoothGattServerCallback callback)

Open a GATT Server The callback is used to deliver results to Caller, such as connection status as well as the results of any other GATT server operations. The method returns a BluetoothGattServer instance. You can use BluetoothGattServer to conduct GATT server operations.

Parameters
`context`	`Context`: App context
`callback`	`BluetoothGattServerCallback`: GATT server callback handler that will receive asynchronous callbacks.

Returns
`BluetoothGattServer`	BluetoothGattServer instance
