, 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

Technologies and Usage

Discovery

JABWT provides support for discovery of nearby Bluetooth devices. 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. 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. Google maintains

of devices that conform to the JSR-82 specification.

Implementations

Several open-source implementations of the JSR-82 specification are available: * AvetanaBluetooth Implementation * BlueCove: Java Library for Bluetooth
