Definition of the problem

• The design, development, testing and verification
  phases of a Bluetooth system prototype will be
  accomplished using J2ME.
• A client application simulating mobile equipment
  with a Bluetooth module having multimedia
  capabilities will be implemented.
• A server application putting emphasis on the wide
  range of applicability of Bluetooth will be
  developed.
• Bluetooth protocol stacks will be examined and
  one of them may be used or a new one will be
  developed.
• The theoretical and practical issues like file
  transfer, ad-hoc networking, device
  synchronization, peripheral connectivity will be
  investigated.

Justification for the problem chosen

• One of our project aims is to see what todays
  technology can do for tomorrow and how tomorrows
  world will look like. In other words
• Combine Bluetooth with J2ME in a multimedia
  environment.
• Client/Server Application and its implementation
  in wireless environments.

Previous work
gtgt Projects Overview

• JSIS Java Student Information SystemDevelop
  a system that will enable students to perform
  their tasks in an easy way and will let them
  access needed information from anywhere and
  anytime they want!With whatever technology
  they have (Internet, Mobile Devices, PDAs, etc)
• JVS Java Video Streaming Enable users to
  access any needed media data (audio/video) by
  means of a mobile device any time needed"

Previous work
gtgt Technologies Used

• JSIS Java Student Information System- J2ME
  (MIDP 1.0)- Servlets/JSP- Database Programming
  (Oracle)
• JVS Java Video Streaming
• - J2ME (MIDP 2.0) - MMAPI (Multimedia
  API) - Servlets - Database Programming (Oracle)

Background
gtgt Bluetooth

• What is Bluetooth ?
• Short-range
• Secure radio waves
• Conceived as basic cable replacement technology
• Operates in the 2.4 GHz Industrial, Scientific,
  and Medical(ISM) band which is unlicensed
• Enables wireless personal ad-hoc networks(PAN)
• Wireless PANs will enable the creation of smart
  environments in which virtually any electronic
  device can be networked

8
Background
gtgt Bluetooth

• SIG (Special Interest Group)
• Charter of SIG was to monitor the technical
  development of a short-range and to create an
  open global standard
• The Bluetooth Specification
• Capable of voice and data communication
• Distance roughly 10 to 100 meters
• Connections
• Ad-Hoc point to point
• Ad-Hoc point to multipoint
• Units can dynamically be added or disconnect from
  the network

9
Background
gtgt Bluetooth

• Protocol Stack

10
Background
gtgt Bluetooth

• Some components are Bluetooth specific (Bluetooth
  Radio)
• Some are reused from other specifications (IP,
  WAP, OBEX)
• Some have been modified for the Bluetooth
  protocol stack (vCard/vCal, WAE, Audio)

11
Background
gtgt Bluetooth

• Profiles

12
Background
gtgt Bluetooth

• Profiles describe how different parts of the
  specification can be used to fulfill a desired
  function for a Bluetooth device
• Profiles present the default solution for a usage
  model and form the basis for Bluetooth
  interoperability and logo requirements
• Each Bluetooth device must support at least one
  profile, but may support several profiles
• If two devices support same profile, then they
  should be able to interoperate

13
Background
gtgt Bluetooth

• Java APIs For Bluetooth Wireless Technology
• JSR-82
• This API is an optional package that can be used
  to extend the capability of J2ME profile, such as
  Mobile Information Device Profile (JSR 37)
• The overall goal of this specification is to
  define a standard set of APIs that will enable an
  open, third-party application enviroment for
  Bluetooth wireless technology

14
Background
gtgt Bluetooth

• This API mainly describes the following contents
• Device Discovery
• Service Discovery
• Service Registration
• Generic Access Profile
• Serial Port Profile
• Logical Link Control and Adaptation Protocol
• Object Exchange Protocol (OBEX)

15
Background
gtgt Java 2 Micro Edition

• What is J2ME?
• Unlike J2SE, J2ME is not a piece of software,
  nor is it a single specification.
• J2ME is a collection of technologies and
  specifications that are designed for different
  parts of the small device market.
• J2ME is divided into configurations and
  profiles.

16
Background
gtgt Java 2 Micro Edition

• Configurations - Details of virtual machine -
  Base set of APIs
• Profile- Builds on a configuration - Adds more
  specific APIs to make a complete environment for
  building applications.
• (MIDP, MMAPI)

17
Background
gtgt Java 2 Micro Edition

• CLDC Connected, Limited Device
  Configuration The Mobile Information
  Device Profile (MIDP), which is based on CLDC,
  is the first finished profile and thus the first
  finished J2ME application environment. We will
  use MIDP 2.0 since it contains MMAPI (Multimedia
  API)

18
Solution for the problem

• We are going to implement Java and Bluetooth
  enabled Client/Server application.
• At Client side (MIDP 2.0 compatible mobile
  device) will be used for audio/video playback.
• Server side will be implemented using Servlet
  technology according to Front Controller Design
  Pattern.

19
Implementation

• At the present moment we do not have a complete
  implementation of our project, but still we will
  be showing you two demos we were working on all
  these time.
• Server side is implemented by Nasif Ekiz
• Client side is implemented by M.Mamedov
• JVS Demohttp//jvs.turkmenweb.com
• Rococo Bluetooth Simulator Demo

20
Future work

• In the future we are going to develop
  Client/Server application of the JVS which will
  be using Bluetooth technology as the main way of
  communication and data transfer between Client
  and Server.

21
Summary

• We learnt and implemented two challenging
  technologies of tomorrow already available today,
  Bluetooth and J2ME. We also learnt how Bluetooth
  is integrated with J2ME environment.
• We developed an application (JVS) that performs
  audio/video streaming using J2ME.
• It is lacking Bluetooth part only.

• Thank you!
