3. 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.

4. Justification for the problem chosen • One of our project aims is to see what today’s technology can do for tomorrow and how tomorrow’s world will look like. In other words: • Combine Bluetooth with J2ME in a multimedia environment. • Client/Server Application and its implementation in wireless environments.

5. Previous work >> Projects Overview • JSIS – Java Student Information System“Develop 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"

6. Previous work >> 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)

7. Background >> 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 >> 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 >> Bluetooth • Protocol Stack

10. Background >> 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 >> Bluetooth • Profiles

12. Background >> 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 >> 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 >> 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 >> 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 >> 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 >> Java 2 Micro Edition CLDC – Connected, Limited Device ConfigurationThe 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.

22. The End Thank you!
