public BluetoothAdapter getAdapter ()
Get the BLUETOOTH Adapter for this device.
Returns | |
---|---|
BluetoothAdapter |
the BLUETOOTH Adapter |
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. |
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 |
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. |
public BluetoothGattServer openGattServer (Context context, BluetoothGattServerCallback callback)
