Abstract-- Bluetooth chatting is an innovative approach
to the mobile world. A low –power and low –cost connection
is provided by the Bluetooth among mobile devices and
their accessories. It is basically an open standard for
implementing a short range wireless communication. This
application allows two Android devices to carry out twoway
text chat over Bluetooth. This shows the use of
Bluetooth in terms of chatting. The paper contains design
and implementation of Bluetooth Communication by using
APIs of Android platform. The APIs wirelessly connect
applications to other Bluetooth devices, enabling point-topoint
and multipoint wireless features
INTRODUCTION
The Android platform support for the Bluetooth
network stack. It allows a device to wirelessly exchange
data with other Bluetooth devices. The new vitality to the
mobile space has injected because of the release of
Android smart platform. Android is an operating system
based on Linux kernel. It is designed for the touch screen
mobile devices. The user interface of Android is based on
direct manipulation. The Android system provides many
Bluetooth APIs for developers to call.[1]
Bluetooth technology allows users to exchange voice
and data transmission between two or more devices. It is
basically a wireless communication technology.
Bluetooth technology is reflected in the low price, easy to
control and non-visual distance limitations. Bluetooth is
integrated into the android platform as an android mobile
network communication module. Chat room is used to
connect the Android phones into a local area network. It
helps to communicate with each other
By the help of the Bluetooth module, the Android
phones can be divided into client and server. Chat can be
accomplished only after the division of client and server.
It is used to initialize the connection.
Bluetooth does not need a license around the globe for
the working frequency band. In the connection
initialization phase, firstly, it starts the application and
search the Bluetooth devices. Second, it sends the signals
to the server class. After this it can run, pause and stop
the application. Third, it shows alert using setAlert
function on every changing. Server goes active and sends
the signals to other devices. Client class works to respond
the other Bluetooth device server. This allows a two-way
chat over Bluetooth. No GSM or Wi-Fi connection
required. In addition to the person-to-person chat, chat
rooms can be used to gather more than two persons at a
time.
