| * Represents the local device Bluetooth adapter. The {@link BluetoothAdapter} lets you perform | |
| * fundamental Bluetooth tasks, such as initiate device discovery, query a list of bonded (paired) | |
| * devices, instantiate a {@link BluetoothDevice} using a known MAC address, and create a {@link | |
| * BluetoothServerSocket} to listen for connection requests from other devices, and start a scan for | |
| * Bluetooth LE devices. | |
| * | |
| * <p>To get a {@link BluetoothAdapter} representing the local Bluetooth adapter, call the {@link | |
| * BluetoothManager#getAdapter} function on {@link BluetoothManager}. On JELLY_BEAN_MR1 and below | |
| * you will need to use the static {@link #getDefaultAdapter} method instead. | |
| * | |
| * <p>Fundamentally, this is your starting point for all Bluetooth actions. Once you have the local | |
| * adapter, you can get a set of {@link BluetoothDevice} objects representing all paired devices | |
| * with {@link #getBondedDevices()}; start device discovery with {@link #startDiscovery()}; or | |
| * create a {@link BluetoothServerSocket} to listen for incoming RFComm connection requests with | |
| * {@link #listenUsingRfcommWithServiceRecord(String, UUID)}; listen for incoming L2CAP | |
| * Connection-oriented Channels (CoC) connection requests with {@link #listenUsingL2capChannel()}; | |
| * or start a scan for Bluetooth LE devices with {@link BluetoothLeScanner#startScan(ScanCallback)} | |
| * using the scanner from {@link #getBluetoothLeScanner()}. | |
