Bluetooth Application Programming with the Java APIs by Timothy J. Thompson

By Timothy J. Thompson

The e-book offers an in depth and insightful look at programming Bluetooth purposes in JavaME, with plenty of programming examples. I train a direction on cellular and pervasive computing, and this ebook has been definitely invaluable. i've been watching for this sort of booklet - each one layer of the protocol stack is taken into account, and the way to application at various layers of the protocol stack is defined.

Making Java Groovy


Making Java Groovy is a pragmatic guide for builders who are looking to mix Groovy into their daily paintings with Java. It starts off by way of introducing the foremost ameliorations among Java and Groovy—and how one can use them for your virtue. Then, it publications you step by step via reasonable improvement demanding situations, from internet purposes to internet prone to computer purposes, and exhibits how Groovy makes them more uncomplicated to place into production.

About this Book

You don't desire the entire strength of Java whilst you're writing a construct script, an easy procedure application, or a light-weight net app—but that's the place Groovy shines brightest. This dependent JVM-based dynamic language extends and simplifies Java so that you can be aware of the duty to hand rather than dealing with minute information and pointless complexity.

Making Java Groov is a pragmatic advisor for builders who are looking to take advantage of Groovy of their paintings with Java. It begins through introducing the main changes among Java and Groovy and the way to take advantage of them in your virtue. Then, you'll specialize in the events you face each day, like eating and developing RESTful internet providers, operating with databases, and utilizing the Spring framework. You'll additionally discover the nice Groovy instruments for construct tactics, trying out, and deployment and how one can write Groovy-based domain-specific languages that simplify Java development.

Written for builders acquainted with Java. No Groovy adventure required.

The Consumer and embedded space covers a range of devices from pagers to television settop boxes that vary widely in memory, processing power, and I/O capabilities. To address this diversity, the Java ME architecture defines What Is JAVA ME? 6 Java platforms. configurations, profiles, and optional packages to allow for modularity and customizability. 7 shows the high-level relationship between layers of the Java ME architecture. The layers are explained further in the next section. 1 Configurations A Java virtual machine interprets the Java byte codes generated when Java programs are compiled.

Prevent applications from interfering with each other. The concept of the Bluetooth Control Center (BCC), discussed in Chapter 3, was introduced for this reason. The intent of the BCC is to allow multiple Bluetooth applications to run simultaneously and be able to access Bluetooth resources. 6. Ability of applications to be both client and server to enable peerto-peer networking. This is one of the vital use cases for Bluetooth API Characteristics and Hardware Requirements 29 wireless technology.

4 shows, the BCC is not directly accessible with JABWT applications. Instead, the JABWT implementation issues requests through the BCC to the Bluetooth stack. The BCC also can be used by native applications. The BCC can prevent conflicting requests between the JABWT applications and the native applications. How does a user modify the values of the BCC? This procedure also is up to an implementation of the BCC. It is expected that most implementations will use a native application to manipulate the settings in the BCC.
