Opening a Client Bluetooth Socket Connection


To initiate a communications channel to a remote device,
create a Bluetooth Socket from the BluetoothDevice object
that represents it.

To create a new connection call createRfcommSocket
ToServiceRecord on the Bluetooth Device to connect to,
passing in the UUID of the Bluetooth Server Socket accepting
requests.

If you attempt to connect to a Bluetooth Device that has
not yet been paired (bonded) with the host device, you will
be prompted to accept the pairing before the connect call    
completes, as shown in Figure

The user must accept the pairing request on both the host
and remote devices for the connection to be
established.



NOTE::
connect is a blocking operation, so it’s best practice to initiate
connection requests on a background thread rather than block the UI thread until a
connection has been made.


Connecting to a remote Bluetooth server


 Try{
      BluetoothDevice device = bluetooth.getRemoteDevice("00:23:76:35:2F:AA");
     BluetoothSocket clientSocket =
    device.createRfcommSocketToServiceRecord(uuid);
    clientSocket.connect();

} catch (IOException e) {
       Log.d("BLUETOOTH", e.getMessage());
}

Bluetooth Data Transfer Example

The following example uses the Android Bluetooth APIs to construct a simple peer-to-peer messaging system that works between two paired Bluetooth devices. Unfortunately the Android emulator can’t currently be used to test Bluetooth functionality. In order to test this application you will need to have two physical devices. 1. Start by creating a new BluetoothTexting project featuring a BluetoothTexting Activity. Modify the manifest to include BLUETOOTH and BLUETOOTH_ADMIN permissions. <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.paad.chapter13_bluetoothtexting" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".BluetoothTexting" android:label="@string/app_name"> <in
