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 getSystemService(java.lang.String)
with BLUETOOTH_SERVICE to create an BluetoothManager,
then call getAdapter() to obtain the BluetoothAdapter.
Alternately, you can just call the static helper
getDefaultAdapter().
For more information about using BLUETOOTH, read the Bluetooth developer guide.

BluetoothAdapter getAdapter ()
Get the default BLUETOOTH Adapter for this device.
| Returns | |
|---|---|
BluetoothAdapter |
the default BLUETOOTH Adapter |
List<BluetoothDevice> getConnectedDevices (int profile)
Get connected devices for the specified profile.
Return the set of devices which are in state 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 BLUETOOTH permission.
| Parameters | |
|---|---|
profile |
int:
GATT or GATT_SERVER |
| Returns | |
|---|---|
List<BluetoothDevice> |
List of devices. The list will be empty on error. |
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 BLUETOOTH permission.
| Parameters | |
|---|---|
device |
BluetoothDevice:
Remote bluetooth device. |
profile |
int:
GATT or GATT_SERVER |
| Returns | |
|---|---|
int |
State of the profile connection. One of
STATE_CONNECTED, STATE_CONNECTING,
STATE_DISCONNECTED,
STATE_DISCONNECTING
|
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 BLUETOOTH permission.
| Parameters | |
|---|---|
profile |
int:
GATT or GATT_SERVER |
states |
int:
Array of states. States can be one of
STATE_CONNECTED, STATE_CONNECTING,
STATE_DISCONNECTED,
STATE_DISCONNECTING, |
| Returns | |
|---|---|
List<BluetoothDevice> |
List of devices. The list will be empty on error. |
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 |
