BluetoothServerSocket

Class Overview

A listening Bluetooth socket.

The interface for Bluetooth Sockets is similar to that of TCP sockets: Socket and ServerSocket . On the server side, use a BluetoothServerSocket to create a listening server socket. When a connection is accepted by the BluetoothServerSocket , it will return a new BluetoothSocket to manage the connection. On the client side, use a single BluetoothSocket to both initiate an outgoing connection and to manage the connection.

The most common type of Bluetooth socket is RFCOMM, which is the type supported by the Android APIs. RFCOMM is a connection-oriented, streaming transport over Bluetooth. It is also known as the Serial Port Profile (SPP).

To create a listening BluetoothServerSocket that's ready for incoming connections, use BluetoothAdapter.listenUsingRfcommWithServiceRecord() . Then call accept() to listen for incoming connection requests. This call will block until a connection is established, at which point, it will return a BluetoothSocket to manage the connection. Once the BluetoothSocket is acquired, it's a good idea to call close() on the BluetoothServerSocket when it's no longer needed for accepting connections. Closing the BluetoothServerSocket will not close the returned BluetoothSocket .

BluetoothServerSocket is thread safe. In particular, close() will always immediately abort ongoing operations and close the server socket.

Note: Requires the BLUETOOTH permission.

String toString () Returns a string containing a concise, human-readable description of this object. final void wait () Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait (long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait (long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
