<p class="note"><strong>Note:</strong>

<p>

To perform Bluetooth communication using these APIs, an application must

declare the {@link android.Manifest.permission#BLUETOOTH} permission. Some

additional functionality, such as requesting device discovery and

pairing also requires the {@link android.Manifest.permission#BLUETOOTH_ADMIN}

additional functionality, such as requesting device discovery,

also requires the {@link android.Manifest.permission#BLUETOOTH_ADMIN}

permission.

<h3>Overview</h3>

<p>Here's a basic introduction to the Bluetooth classes:</p>

<dl>

  <dt>{@link android.bluetooth.BluetoothAdapter}</dt>

  <dd>This represents the local Bluetooth adapter, which is essentially the

  entry-point to performing any interaction with Bluetooth. With it, you can

  discover other Bluetooth devices, query a list of bonded (paired) devices,

  initialize a {@link android.bluetooth.BluetoothDevice} using a known MAC

  address, and create a {@link android.bluetooth.BluetoothServerSocket} to

  listen for communications from other devices.</dd>

  <dt>{@link android.bluetooth.BluetoothDevice}</dt>

  <dd>This represents a remote Bluetooth device. Use this to request a

  connection with a remote device through a

  {@link android.bluetooth.BluetoothSocket}

  or query information about the device such as its name, address, class, and

  bonding state.</dd>

  <dt>{@link android.bluetooth.BluetoothSocket}</dt>

  <dd>This represents the interface for a Bluetooth socket

  (similar to a TCP client-side {@link java.net.Socket}). This is the

  connection point that allows an app to transfer data with another Bluetooth

  device via {@link java.io.InputStream} and {@link java.io.OutputStream}.</dd>

  <dt>{@link android.bluetooth.BluetoothServerSocket}</dt>

  <dd>This represents an open server socket that listens for incoming requests

  (similar to a TCP server-side {@link java.net.ServerSocket}).

  When attempting to connect two Android devices, one device will need to open

  a server socket with this class. When a connection is accepted, a new

  {@link android.bluetooth.BluetoothSocket} will be returned,

  which can be used to manage the connection and transfer data.</dd>

  <dt>{@link android.bluetooth.BluetoothClass}</dt>

  <dd>This represents the Bluetooth class for a device which describes general

  characteristics and capabilities of a device. This class and its subclasses

  don't provide any actual functionality. The sub-classes are entirely composed

  of constants for the device and service class definitions.</dd>

</dl>

<h3>Example Procedure</h3>

<p>For example, here's an pseudo-code procedure for discovering and

connecting a remote device, and transfering data:</p>

<ol>

  <li>Register a {@link android.content.BroadcastReceiver} that accepts the

  {@link android.bluetooth.BluetoothDevice#ACTION_FOUND} Intent.</li>

  <li>Call {@link android.bluetooth.BluetoothAdapter#getDefaultAdapter} to

  retrieve the Android system's local

  {@link android.bluetooth.BluetoothAdapter}.</li>

  <li>Call {@link android.bluetooth.BluetoothAdapter#startDiscovery()

  BluetoothAdapter.startDiscovery()} to scan for local devices. This is where

  the BroadcastReceiver comes in; Android now scans for devices and will

  broadcast the {@link android.bluetooth.BluetoothDevice#ACTION_FOUND} Intent

  for each remote device discovered. The

  {@link android.content.BroadcastReceiver}

  you created will receive each Intent.</li>

  <li>The {@link android.bluetooth.BluetoothDevice#ACTION_FOUND} Intent

  includes the {@link android.bluetooth.BluetoothDevice#EXTRA_DEVICE}

  Parcelable extra, which is a {@link android.bluetooth.BluetoothDevice}

  object. Extract this from the Intent and call

  {@link android.bluetooth.BluetoothDevice#createRfcommSocketToServiceRecord(java.util.UUID)

  BluetoothDevice.createRfcommSocketToServiceRecord()}

  to open a {@link android.bluetooth.BluetoothSocket} with a chosen

  remote device.</li>

  <li>Call {@link android.bluetooth.BluetoothSocket#connect()

  BluetoothSocket.connect()} to connect with the remote device.</li>

  <li>When successfully connected, call

  {@link android.bluetooth.BluetoothSocket#getInputStream()

  BluetoothSocket.getInputStream()} and/or

  {@link android.bluetooth.BluetoothSocket#getOutputStream()

  BluetoothSocket.getOutputStream()} to retreive an

  {@link java.io.InputStream} and {@link java.io.OutputStream}, respectively,

  which are hooked into the socket.</li>

  <li>Use {@link java.io.InputStream#read(byte[]) InputStream.read()} and

  {@link java.io.OutputStream#write(byte[]) OutputStream.write()} to transfer

  data.</li>

</ol>

<h2>Bluetooth</h2>

<p>The Bluetooth APIs allow applications to scan, connect and pair with other Bluetooth devices.

THESE APIS ARE NOT YET AVAILABLE.</p>

<p>The Android platform includes support for the Bluetooth network stack, which allows a device to

wirelessly exchange data with other Bluetooth devices. The application framework provides access to

the Bluetooth functionality through the Android Bluetooth APIs. These APIs let applications

wirelessly connect to other Bluetooth devices, enabling point-to-point and multipoint wireless

features.</p>
