+     * Create a listening, insecure RFCOMM Bluetooth socket with Service Record.
+     * <p>The link key will be unauthenticated i.e the communication is
+     * vulnerable to Man In the Middle attacks. For Bluetooth 2.1 devices,
+     * the link key will be encrypted, as encryption is mandartory.
+     * For legacy devices (pre Bluetooth 2.1 devices) the link key will not
+     * be encrypted. Use {@link #listenUsingRfcommWithServiceRecord}, if an
+     * encrypted and authenticated communication channel is desired.
+     * <p>Use {@link BluetoothServerSocket#accept} to retrieve incoming
+     * connections from a listening {@link BluetoothServerSocket}.
+     * <p>The system will assign an unused RFCOMM channel to listen on.
+     * <p>The system will also register a Service Discovery
+     * Protocol (SDP) record with the local SDP server containing the specified
+     * UUID, service name, and auto-assigned channel. Remote Bluetooth devices
+     * can use the same UUID to query our SDP server and discover which channel
+     * to connect to. This SDP record will be removed when this socket is
+     * closed, or if this application closes unexpectedly.
+     * <p>Use {@link BluetoothDevice#createRfcommSocketToServiceRecord} to
+     * connect to this socket from another device using the same {@link UUID}.
