1. Bluetooth is an open wireless protocol for exchanging data
over short distances (using short length radio waves) from
fixed and mobile devices .
2. Bluetooth is actually a standard for wireless
communications between devices within a range of
10metres.
3. This technology enable users to automatically and easily
connect a wide range of computing and telecommunication
devices.
WHAT IS BLUETOOTH TECNOLOGY ?

Bluetooth uses a technique called spread-spectrum frequency hopping.
In this technique, a device will use 79 individual, randomly
chosen frequencies within a designated range
AVOIDING INTERFERENCE: HOPPING

1. Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data
being sent and transmits chunks of it on up to 79
frequencies.
2. Unlike infra-red, Bluetooth does not require any line-of-
sight positioning of connected devices like Infra-red.
3.Pico net is the important factor in Bluetooth connectivity.
It is simply a collection of Devices connected through
Bluetooth, possessing Master-Slave relationship.
HOW BLUETOOTH TECHNOLOGYWORKS ?

4. Two Bluetooth products can exchange their addresses and
capabilities just after coming within the range of about10metres.
5. The radio operates on the globally-available unlicensed
radio band, 2.45 GHz and supports data speeds of up to 721Kbps.
6. Connections can be point-to-point or multipoint. The
maximum range is 10 meters but can be extended to 100
meters by increasing the power.

What we will be Doing ?
MOBILE APPLICATION BASED PROJECT
1. It will provide messaging system between two
mobiles connected via bluetooth.2. Like any other chatting system, it will list the
number of available members having bluetoothactive on their device.
3. It will allow chatting between any two of the activemembers at a time.
4. The best feature will be that it will be free of cost.

Why this project??
1. this project will help the users to use their mobilesmore effectively.
2. more mobility,more freedom.
no more does the user has to depend on network.So even if you are at a place where there is nonetwork,you can still chat.
3. cost effective.
this application will allow the users to chat free of cost.
4. added mobility.no tention of wires.

What we have done ?
User can Chat with other device without anydisturbance at one person at a time.
Created a Front End for Users to interact with otherdevices using our Application.
We have defined FOUR categories in our Interfacei. ADD USERS
ii.
DELETE USERSiii. SEARCH USERS
iv. LIST USERS

Continued
SEARCH USERS :When User selects this option then ,It Enables user to search all BLUETOOTH deviceswhich are active within a range.
ADD USERS :When all the BLUETOOTH devices aresearched, If user select this option for any particularsearched device , Then It will be added as a friend in
the List of Currently available users.

Continued.
LIST USERS :When user selects this option , then it willshow all the users currently available for messaging.When user select any one of the friend from the listthen messaging is Enabled for that user.
DELETE USERS : When user select this option, It willdelete any user from the currently available list of
friend, If user does not like to chat with it.

The Bluetooth Service ModelBluetooth devices can offer Client and Server
functionality at the same time. On a hardwarelevel, a single master Bluetooth device cansynchronize up to seven slave devices in aBluetooth piconet.
Devices are the discoverable entities in aBluetooth network. The discovery process is
called an inquiryin Bluetooth lingo. You needto perform an inquiry to discover devices inyour PAN before finding out what services thedevices are offering.
Each service in a Bluetooth network is
uniquely identified by a UUID.Any particulardevice in the Bluetooth network can beoffering zero or more services. The sameservice may be offered by more than onedevice in the network.

ALGORITHM FOR OUR APPROACH.
1. START
2. SWITCH ON THE BLUETOOTH IN ALL THEDEVICES.
3. The devices will ask for security issues and ask if userwants to switch on the bluetooth.
4. The user then accepts the security issues and grantspermission to the device to switch on bluetoth for thedevice.

5. The bluetooth then looks for all the devices presentwithin the range. This is the searching part.
6. The device then lists all the users present.
7. Then we select 1 user from the available users and
connect our device using bluetooth to the other device.
8. A connection is established between 2 users.
9. Now they can start shatting using this application.

start
Switch on the device.
The devices will ask for security issues and ask
switch on bluetooth of your device
NO
Search all the devices present .
List all the devices present.
The user selects 1 user from the available list of users
Close application
YES
A connection is then established between both the users usingbluetooth.
The users can now start chatting.
Close the application.

OBJECTIVEEven though there need for good communication skills is
stressed upon, we observe that people dont communicate
freely in face to face interactions.
Our application allows the user to overcome this hurdle
allowing people to have a friendly communication. It also
allows people to communicate silently in their workplaces.
The application provides the basic requirements and neat
graphical user interface to chat.
Mainly Inexpensive.

1 Bluetooth is wireless and automatic. You don't have to
keep track of cables, connectors, and connections, andyou don't need to do anything special to initiate
communications.
2 Bluetooth is inexpensive.
3 The ISM band that Bluetooth uses is regulated, butunlicensed. Governments have converged on a singlestandard, so it's possible to use the same devices
virtually wherever you travel.
BLUETOOTH APPLICATIONS

APPLICATION CONT
4 Bluetooth uses frequency hopping. Its spreadspectrum approach greatly reduces the risk thatcommunications will be intercepted.
5. There is no need of transceivers or base stations totransfer the signal.
6. Any where you can chat with your friend if the deviceis within range.

ADVANTAGES OF BLUETOOTH
TECHNOLOGY1 Bluetooth Devices are Wireless thus reducing
the overhead and expanses of wired set up.
2 Most important feature is that, Bluetooth
Technology is Inexpensive.
3 Low Energy Consumption.

ADVANTAGES CONT
4. Bluetooth is Automatic, just activate your device
once connected you can share data.
5. Share Voice and Data, like pictures, videos, data
file etc. AND the list continues

1. Bluetooth devices can not be connected with morethan one devices at a time, as it finds problem in
discovering the intended recipient device.
2. Bluetooth has a low data rate( i.e.1 MBps) incomparision to infra-red(i.e.4 MBps).
3. Small throughput rates- Data Rate 1.0 Mbps
DISADVANTAGES OF BLUETOOTH
-
8/4/2019 Presentation on Chatting in Mobile Using Bluetooth
24/32
1. Bluetooth will be able to complete all other wireless
technologies, such as Wi-Fi networking , infra-red data
association , etc.
2. With Bluetooth based chatting and file transfer system,
things will not only become easier, but a newer outlook to
the bluetooth technology will be developed.
3. People will be able to chat at places where they have no
towers, no networks.
4. Enhancement of mobile utilization.
