Bluetooth is a wireless technology for communication over distances of up to 10m, offering reasonably fast data transfer rates of around 1 Mb/s, principally between battery-powered devices. Bluetooth's primary intent is to support the creation of ad-hoc personal area networks (PANs) for small data transfers (or voice communication) between devices such as phones and PDAs. The principal aim of this chapter is to introduce J2ME's Bluetooth API (known as JSR 82) by explaining how to use it in a simple client/server application. A client searches for Bluetooth devices and services, connects to a matching server, and sends messages to it. Many of the Bluetooth-related classes developed here will be used in later chapters. JSR 82 Details JSR 82 is a Java layer over a Bluetooth software stack which hides the underlying Bluetooth hardware or firmware in the device. Sources of more information on JSR 82 and Bluetooth are listed at the end of this chapter. The stream

Bluetooth is widely acknow-ledged as finally coming into its own as consumers begin to un-derstand its functionality. The Bluetooth Spe-cial Interest Group (SIG) has ex-panded to include more 3000+ members across industries such as communications, medical and personal computing. For product managers and design engineers, the question has changed from "When will we implement Bluetooth?" to "How will we implement Bluetooth in our designs?" As a result, the lat-est module solutions offer de-signers the means to imple-ment Bluetooth technology with reduced design risk, mak-ing the reality of a drop-in "complete Bluetooth solution" even more possible (Figure 2). A major consideration when adding Bluetooth functionality to a design is if the module or chipset meets the current Bluetooth standard and/or if it is upgradable. Standard Bluetooth devices are minimally equipped with a host controller interface (HCI) stack, which supports basic Bluetooth

today demonstrated for the first time a Windows-powered Pocket PC using Bluetooth wireless technology to send and receive email by making a cable-free connection to a DENSO Bluetooth-enabled mobile phone on the Sprint PCS nationwide wireless data network. The software that allows a Pocket PC to communicate with a Bluetooth-enabled phone will be available this month to developers who purchase Socket's Bluetooth Personal Network Card Evaluation Kit. "Giving a Pocket PC cordless access to a mobile phone for dial-up networking on the Sprint PCS network is a major milestone for Socket," said Peter Phillips, director of product marketing for Socket. "We've worked closely with Sprint PCS, DENSO and Microsoft to create a virtual single-body solution - an Internet-connected Pocket PC that offers the convenience of an embedded wireless modem but that takes advantage of Socket's low-power, general-purpose Bluetooth card to communicate with a mobile phone that could be stored out of the

The short-range radio system Bluetooth will be bringing more comfort to automobiles in the future. It links a variety of devices such as the car radio, mobile phone, PDA (personal digital assistant) and headset, and has the potential to become a universal communication interface between the vehicle and the outside world. Currently, Bluetooth is most frequently used in the hands-free telephone units now required for cars. The 2.4 GHz technology of Bluetooth can do much more. However, researchers at Bosch believe that Bluetooth's most impor-tant function will be to link together the vari-ous multimedia devices in an automobile. Bluetooth can thus perform two important functions: exchanging data between portable terminals and the car, and enabling the wire-less transfer of audio and video signals for entertainment and information. To take just one example, the driver's children in the back seat will be able to control the car radio from a PDA via Bluetooth while listening

As mobile terminals with Bluetooth properties emerge an intelligently working guidance system becomes available. Our approach on a wireless guidance system is based on Bluetooth technology and Bluetooth enabled mobile terminals. With Bluetooth technology this delay gets too big for almost every real time application because the searching of surrounding devices (inquiry) is very time consuming operation. This paper reveals some of the problems of using Bluetooth technology in real time systems and introduces one possible solution with its implementation to bypass these problems. Its duration is hard to predict because the time taken to find surrounding Bluetooth devices by using Bluetooth inquiry can vary a lot [4]. The idea of the implemented Bluetooth guidance system is to skip the whole inquiry process or at least minimize its effect when forming connection between devices. When the registration message is sent to the access point the Bluetooth device address

New DSP technology delivers market-leading features in a smaller package Utilizing Gennum's multi-processor DSP which delivers 42 MIPS of digital processing at a mere 1 milliwatt of power consumption, the next-generation Z-E-NT headset creates a high-quality listening experience - on or off the phone - and also adds new features that make it a truly multi-functional device.

The result is Bluetooth, a technology named after a 10th-cen-tury king who brought warring Viking tribes under a common rule. The Bluetooth specifications,1,2 currently in version 1.1, define a radio frequency (RF) wireless communication interface and the associated set of communication protocols and usage profiles. While most early Bluetooth solutions are dual chip, vendors have recently announced single-chip versions as well. In this overview of the technology, I will first describe the lower layers of the Bluetooth protocol stack. Bluetooth peers must exchange several control messages for the purpose of configuring and managing the baseband con-nections. Bluetooth is unique in offering the front-end RF processing integrated with the baseband module. Since no hardware-specific knowledge is needed, the Bluetooth stack software can easily be ported from one Bluetooth chip to another. It is relatively easy to port a Bluetooth stack from one platform to another because the

An IEEE working group has been estab-lished to investigate ways to limit the level of interference between 802.11b and Bluetooth devices. Bluetooth could replace this technology, eliminating the need to properly align the infrared (IR) ports of the defibrillator and computer. Assuming that the additional hardware required to support the Bluetooth radio has been added, application software must be de-veloped to communicate through the protocol stack. This routine instructs the radio hardware to look for other Bluetooth-enabled devices within radio range, which is typically 30 ft. Devices within this range respond to this INQUIRY message to inform the client of their presence. This operation is mandatory because Bluetooth is a commercial standard and several different Bluetooth-enabled devices may be within the 30- ft service area. Basically, an application architecture has been examined for both embedded and PC-based Bluetooth solutions. The Bluetooth stack re-quires .005

Bluetooth wireless technology is an open, accepted standard for wireless communication which means that Bluetooth electronic equipment can communicate as long as they are within approx. The mobile telephone manufacturer Ericsson invented Bluetooth technology, naming it after the Viking King Harald Bluetooth. Just as King Harald Bluetooth united Denmark and Norway, Bluetooth technology "unites" various types of electronic equipment to form a coherent whole. As Bluetooth technology becomes more common, however, we will undoubtedly see CD players that send sound to ampliﬁers via Bluetooth, which then transfer the sound to speakers in the same way. If Bluetooth units are to communicate without others listening in, Bluetooth electronic equipment must be paired. The following example shows how simple it is to connect a Jabra BT250 Bluetooth headset to, for example, a Sony Ericsson T610 mobile phone with Bluetooth: Bluetooth class: The standard

In this paper, we propose an energy-e cient scatternet formation algorithm for Bluetooth based sensor networks. The algorithm is based on ﬁrst computing a shortest path tree from the base sta-tion to all sensor nodes and then solving the de-gree constraint problem so that the degree of each node in the network is not greater than seven, which is a Bluetooth constaint. This property of Bluetooth is also important for sensor networks which are also required to be usually self-conﬁguring and dynamic. Bluetooth devices can be categorized into three classes with respect to the energy consumption during transmission. Therefore sup-porting sni and hold modes makes Bluetooth a good technology that can utilize the characteris-tics of sensor networks for energy conservation. What-ever the algorithms is, the ﬁnal scatternet topol-ogy must satisfy the Bluetooth constaints such as each node having at most a degree of seven. Now the problem is constructing a Bluetooth scatternet

We at Palm believe Bluetooth is the optimal technology for PANs because of its small chipset and low power consump-tion, and we are deeply committed to helping Bluetooth become the industry standard for personal wireless devices. The Palm Bluetooth card, which wirelessly enables any Palm handheld equipped with an expansion slot, was one of the earliest Bluetooth products introduced. Targeted for shipment in the first quarter of calendar year 2002, the card enables Palm handhelds to connect to other Bluetooth-enabled devices, such as a cell phone, printer, network access point, or another Palm handheld. PANs offer myriad possibilities for connecting, communicating, and collaborating, such as the following: Connect: A Bridge to the Internet--By far, the most important use of Bluetooth in the near term will be to connect a handheld to the Internet. Initially, a group using Palm handhelds equipped with a Palm Bluetooth card will be able to do things like share a to-do list, but
