Bluetootho wirelessly exchange data with other Bluetooth

devices.o  access to the Bluetooth functionality APIs.o Using the Bluetooth APIs, We can perform the

following: Scan for other Bluetooth devices Query the local Bluetooth adapter for paired Bluetooth

devices Establish RFCOMM channels Connect to other devices through service discovery Transfer data to and from other devices. Tenet Technetronics

BluetoothThe four major tasks necessary to communicate using Bluetooth:osetting up Bluetoothofinding devices that are either paired or available in the local area,oconnecting deviceso transferring data between devices.All of the Bluetooth APIs are available in the android.bluetooth package. 

Tenet Technetronics

To Create Bluetooth ConnectionWe need the following:Bluetooth adapter.Bluetooth device.Bluetooth socket.Bluetooth Server Socket.

Tenet Technetronics

Permissionso you must declare the Bluetooth

permission BLUETOOTH. o If We discover Bluetooth devices or pair a device

we must use Bluetooth Admin permission.o  Most applications need this permission solely for

the ability to discover local Bluetooth devices.

Tenet Technetronics

Setting up Bluetootho Verify device that Bluetooth is supported or not.

o If supported enable Bluetooth as follows

Tenet Technetronics

Setting up Bluetootho Request to switch on the Bluetooth

o Find Bluetooth Devices.find remote Bluetooth devices either through device discovery or by querying the list of paired (bonded) devices.

Tenet Technetronics

Find Bluetooth Device

o Querying Paired Deviceso We can get paired devices by

getBondedDevices().This method will return all the paired devices.

Connecting Deviceso Android(Client)-Robot(Server)o Server’s MAC address to initiate

connection.o Initiate connection by calling connect()

method.o Get Output stream() of the device.o Write using the method write(byte[]).
