4. PROJECT INTRODUCTION
ABSTRACT:
Bluetooth chatting is an innovative approach to the mobile world. This application shows use of
Bluetooth in terms of chatting. Means persons can chat via Bluetooth. The main midlet has just a
list which has two values server and client. By selecting one of these two values, the
corresponding instance is created. Midlet is used to initialize the connection. It does following
thing at here. First, it starts the application and search the Bluetooth device. It sends the signal to
the server class. Second, it can run, pause and stop the application. Third, it shows alert using
setAlert function on every changing. Server class goes active when it go signal from the midlet
class. It sends the hello world string with the string to the other devices. Client class works to
respond the other Bluetooth device server.
Royal Bluetooth chat is a
Bluetooth
messaging. Royal Bluetooth Chat allows you to see other
Bluetooth Chat users around, ping anyone of them, and create either
private
chat
sessions or
public messaging rooms via Bluetooth. This application allows two Android devices to carry out
two-way text chat over Bluetooth. Start the application from the first screen; splash Screeng and
than go to on home page, where a drawer is used to provide many opportunities to the users .
This is an optional step to provide additional information to other chat buddies. Next, select
‗Search' option which attempts to discover other users in the area. Detected user-profiles are
listed as selectable boxes. While a profile is selected, Options menu can be used to view profile
details, initiate a file transfer or to refresh list of detected friends.
PROPOSED SYSTEM:
This is a Bluetooth messaging app you can connect and send messages to other android devices
and see Bluetooth compatible devices around you. No GSM or Wi-Fi connection required all
you need is a two Bluetooth compatible android devices in range of each other and you can text
away. If you have internet connection you can also share messages, images and also files in on
Gmail, face-book and other compatible services. To chat with a user, select it from the list and
press ‗Ping' to send a welcome message. The other user may do the same. As the welcome
message is displayed, use right or left soft key to accept or reject the chat session. Once the
session is accepted, the chat starts with colorful text to differentiate users. In addition to this
person-to-person chat, chat rooms can be used to gather a number of buddies.
ADVANTAGE:
All peers that want to communicate should have Royal Bluetooth Chat running.
It is enough that one peer does the initial ―Search" operation.
Every time a new comer peer does its first "Look for friends" operation, the operation will
reorganize all initial
communication
and profile sharing stuff.
Every peer will have an updated list of profiles around automatically and the profile list will
be displayed to warn everyone about the new comer.
Be aware that if more than one peer do "Look for friends" simultaneously, they might not be
able to see each other (because of Bluetooth running principles)
Be aware that the set up of the profile list might take up to one minute. Therefore be patient.
MODULES:-
Scanning for other Bluetooth devices
This application begins searching for devices as soon as it is opened. Options menu
appear only after a successful or unsuccessful search is complete. Other options are new
message alert - vibrate or sound, and refresh rate setting ranging from 30 seconds to three
minutes. Users can manually refresh the list of users as well. Select a user from the list
and use Options.
Querying the local Bluetooth adapter for paired Bluetooth devices
The
Bluetooth Adapter
is the entry-point for all Bluetooth interaction. Using this, you can
discover other Bluetooth devices, query a list of bonded (paired) devices, instantiate
a
Bluetooth Device
using a known MAC address, and create a
BluetoothServerSocket
to
listen for communications from other devices. Use this to request a connection with a
remote device through a
Bluetooth Socket
or query information about the device such as
its name, address, class, and bonding state. Represents the interface for a Bluetooth
socket (similar to a TCP
Socket
). This is the connection point that allows an application
to exchange data with another Bluetooth device via Input Stream and Output Stream.
Establishing RFCOMM channels/sockets
In the socket programming model, a socket represents an endpoint of a communication
channel. Sockets are not connected when they are first created, and are useless until a call
to either connect (client application) or accept (server application) completes
successfully. Once a socket is connected, it can be used to send and receive data until the
connection fails due to link error or user termination.
An RFCOMM Bluetooth Socket used to accept incoming connections must be attached to
operating system resources with the bind method. Bindtakes in a tuple specifying the
address of the local Bluetooth adapter to use and a port number to listen on. Usually,
there is only one local Bluetooth adapter or it doesn't matter which one to use, so the
empty string indicates that any local Bluetooth adapter is acceptable. Once a socket is
bound, a call to listen puts the socket into listening mode and it is then ready to accept
incoming connections.
Connecting to a remote device
that Bluetooth is enabled. A dialog will appear requesting user permission to enable
Bluetooth. Once a connection is made with a remote device for the first time, a pairing
request is automatically presented to the user. When a device is paired, the basic information
about that device (such as the device name, class, and MAC address) is saved and can be
read using the Bluetooth APIs. Using the known MAC address for a remote device, a
connection can be initiated with it at any time without performing discovery (assuming the
device is within range).
Transferring data over Bluetooth
Check the manual that came with your cellular phone and read the section on Bluetooth
capabilities to see if your phone has a Bluetooth password. Note down the password. Power
on your cellular phone and access the "Settings" option in the main menu. Choose the
"Bluetooth" option if it is immediately available, or choose "Connections" and then
"Bluetooth." Press the option for "Activate Bluetooth.". Repeat the process on the second
phone. Navigate to the folder on your phone that holds the file you want to transfer. Choose
the file and then choose the option to "Send." Press the option to "Send to Phone" and then
press the button to send to a connected Bluetooth phone. Enter in the phone number of the
other phone if your cell does not prompt you to send to an activated Bluetooth phone in
range.

DESIGN PHASE
The purpose of design phase is to plan a solution of the problem specified by the SRS.There are
mainly three phases:-Architecture Design, High level design and Detail design
Architecture design:- It focuses on looking at a system as a combination of many
different components.
DFD of Royal chat:-
High level design:- It identifies the modules that should be built for developing the
system and the specification of these modules.
Detail design:- In this, the internal logic of each of the modules is specified
DFD of DataBase:-
DFD of Server-Socket:-
Database:-SQLite is a relational database management system contained in a C programming library. In
contrast to other database management systems, SQLite is not a separate process that is accessed
from the client application, but an integral part of it.
SQLite is ACID-compliant and implements most of the SQL standard, using a dynamically and
weakly typed SQL syntax that does not guarantee the domain integrity.
SQLite is a popular choice as embedded database for local/client storage in application software
such as web browsers. It is arguably the most widely deployed database engine, as it is used
today by several widespread browsers, operating systems, and embedded systems, among others.
SQLite has many bindings to programming languages.
Features :
SQLite implements most of the SQL-92 standard for SQL but it lacks some features. For
example it has partial support for triggers, and it can't write to views (however it supports
INSTEAD OF triggers that provide this functionality). While it supports complex queries, it still
has limited ALTER TABLE support, as it can't modify or delete columns.
SQLite uses an unusual type system for an SQL-compatible DBMS; instead of assigning a type
to a column as in most SQL database systems, types are assigned to individual values; in
language terms it is dynamically typed. Moreover, it is weakly typed in some of the same ways
that Perl is: one can insert a string into an integer column (although SQLite will try to convert the
string to an integer first, if the column's preferred type is integer). This adds flexibility to
columns, especially when bound to a dynamically typed scripting language. However, the
technique is not portable to other SQL products. A common criticism is that SQLite's type
system lacks the data integrity mechanism provided by statically typed columns in other
products. The SQLite web site describes a "strict affinity" mode, but this feature has not yet been
added.However, it can be implemented with constraints like
CHECK(typeof(x)='integer').
