35. Bluetooth
o
o
o
wirelessly exchange data with other Bluetooth
devices.
access to the Bluetooth functionality APIs.
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
Tenet Technetronics
Transfer data to and from other devices.

36. Bluetooth
The four major tasks necessary to communicate using
Bluetooth:
osetting up Bluetooth
ofinding devices that are either paired or available in the
local area,
oconnecting devices
o transferring data between devices.
All of the Bluetooth APIs are available in the android.bluetooth
package.
Tenet Technetronics

37. To Create Bluetooth Connection
We need the following:
Bluetooth adapter.
Bluetooth device.
Bluetooth socket.
Bluetooth Server Socket.
Tenet Technetronics

38. Permissions
o
o
o
you must declare the Bluetooth
permission BLUETOOTH.
If We discover Bluetooth devices or pair a device
we must use Bluetooth Admin permission.
Most applications need this permission solely for the
ability to discover local Bluetooth devices.
Tenet Technetronics

39. Setting up Bluetooth
o
Verify device that Bluetooth is supported or not.
o
If supported enable Bluetooth as follows
Tenet Technetronics

40. Setting up Bluetooth
o
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.

41. Find Bluetooth Device
Querying Paired Devices
o We can get paired devices by
getBondedDevices().
This method will return all the paired devices.
o

42. Connecting Devices
o
o
o
o
o
Android(Client)-Robot(Server)
Server’s MAC address to initiate
connection.
Initiate connection by calling connect()
method.
Get Output stream() of the device.
Write using the method write(byte[]).

44. Conclusion
o
o
o
o
Android is open to all: industry, developers and
users.
Participating in many of the successful open
source projects.
Aims to be as easy to build for as the web.
Google Android is stepping into the next level of
Mobile Internet.
