The manager will try to initialize a BluetoothAdapter if any Bluetooth adapter is present in the system. There can be only one BluetoothManager at one time, and the reference to it is obtained through the getBluetoothManager() method.īluetoothManager manager = BluetoothManager.getBluetoothManager() A BluetoothManager object provides an entry point for using Bluetooth devices. To start looking at the device, we first must initialize the TinyB library. A wiki entry describing the Texas Instruments Sensor Tag device can be found here: 's_Guide. We will use the HelloTinyB Java sample found in the TinyB repository as an example showing how to write a program that reads data from a GATT Service over Bluetooth LE. Java -cp examples/java/HelloTinyB.jar:/usr/lib/java/tinyb.jar HelloTinyB XX:XX:XX:XX:XX:XX Writing a Bluetooth LE Java IoT application The application requires the MAC address of the Sensor Tag as a first parameter to the program ( XX:XX:XX:XX:XX:XX in the following example). The HelloTinyB (or hellotinyb for C++) example uses a Texas Instruments Sensor Tag, from which it reads the ambient and object temperature. The documentation for the Bluetooth LE API exposed by TinyB can be found online at the following locations: In this guide, the TinyB application uses a Texas Instruments Sensor Tag as a Bluetooth LE device. More details can be found in the online README file.

On other Linux-based systems, TinyB can be used as long as BlueZ* version 5.37 or newer is installed and the bluetoothd daemon has been started with experimental features enabled ( -E flag). This environment as well as TinyB are provided as part of the official Intel® IoT Developer Kit image builds for Intel® Edison boards. The current Bluetooth API in TinyB has been tested with the Java 8 runtime environment (OpenJDK 8). This guide will only cover developing applications using the Java API in TinyB on the Intel® Edison development board. TinyB exposes simple C++ and Java APIs for using Bluetooth LE devices. Support for developing these applications is provided as part of the Intel® IoT Developer Kit, using the open source TinyB project. This document is a guide for creating Java* IoT applications that can access remote Bluetooth* Low Energy devices on IoT platforms, such as the Intel® Edison development board. App.Get access to the new Intel® IoT Developer Kit, a complete hardware and software solution that allows developers to create exciting new solutions with the Intel® Galileo and Intel® Edison boards.
