Java APIs for Bluetooth

Last updated

Java APIs for Bluetooth Wireless Technology (JABWT) is a J2ME specification for APIs that allows Java MIDlets running on embedded devices such as mobile phones to use Bluetooth for short-range wireless communication. JABWT was developed as JSR-82 under the Java Community Process. [1]

Bluetooth is a wireless technology standard for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.

Java Platform, Micro Edition or Java ME is a computing platform for development and deployment of portable code for embedded and mobile devices. Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME.

Java (programming language) Object-oriented programming language

Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented,and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to "bytecode" that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The language derives much of its original features from SmallTalk, with a syntax similar to C and C++, but it has fewer low-level facilities than either of them. As of 2018, Java was according to Github one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.

JSR 82 implementations for Java 2 Platform Standard Edition (J2SE) are also available.

Background

The original Java Specification Request (JSR-82) was submitted by Motorola and Sun Microsystems, [2] and approved by the Executive Committee for J2ME in September 2000. JSR-82 provided the first standardized Java API for Bluetooth protocols, allowing developers to write applications using Bluetooth that work on all devices conforming to the specification. The first version of JSR-82 was released in March 2002. The most recent update to JSR-82, Maintenance Draft Review 4, was released in March 2010. The specification, reference implementation, and Technology Compatibility Kit (TCK) are maintained at Motorola Open Source. [3]

Motorola, Inc. was an American multinational telecommunications company founded on September 25, 1928, based in Schaumburg, Illinois. After having lost $4.3 billion from 2007 to 2009, the company was divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is generally considered to be the direct successor to Motorola, as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was sold to Google in 2012, and acquired by Lenovo in 2014.

Sun Microsystems defunct computer hardware and software company which was based in Santa Clara

Sun Microsystems, Inc. was an American company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Sun was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California, on the former west campus of the Agnews Developmental Center.

A Technology Compatibility Kit (TCK) is a suite of tests that at least nominally checks a particular alleged implementation of a Java Specification Request (JSR) for compliance. It is one of the three required pieces for a ratified JSR in the Java Community Process, which are:

Technologies and Usage

Discovery

JABWT provides support for discovery of nearby Bluetooth devices. [4] Java applications can use the API to scan for discoverable devices, identify services provided by discovered devices, and search for devices that the device frequently contacts.

Object Exchange APIs

JABWT provides an object exchange API for transfer of data objects between devices. For example, two devices conforming to the OBEX protocol could exchange virtual business cards or calendar appointments.

Device Management

JABWT allows management of the local device’s state. [5] JABWT applications are able to access information about the host device (such as Bluetooth address), mark their host device as discoverable to other Bluetooth devices, and register to provide services.

Security

JABWT supports connections with different levels of security. Applications using the APIs can pass parameters to the Connector.open() method indicating the level of security required to establish a connection to another device.

Compatible Devices

Hundreds of mobile devices from different manufacturers comply with the JSR-82 specification. [6] Google maintains a list of devices that conform to the JSR-82 specification.

Implementations

Several open-source implementations of the JSR-82 specification are available:

Java virtual machine runtime environment that can execute Java bytecode as a result of compiling computer programs written in the Java programming language

A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required of a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform.
