A Service is a set of features that encapsulate the behavior of the peripheral device. ![]() In the GATT architecture, data is organized into services and characteristics. To learn more about the Bluetooth LE and GATT, see and. The ATT transports the attributes and the attributes are formatted as characteristics and services. The GATT is built on top of the Attribute Protocol (ATT). These small data transmissions over a BLE link are called attributes. The GATT profile is a way of specifying small transmission data over the BLE link. GATT defines a hierarchical data structure that is exposed to connected Bluetooth LE devices. The Arduino 101* Bluetooth LE is based on the Generic Attribute Profile (GATT) architecture. įigure 2: Central and peripheral device communication. This project will use the angle rotary sensor from the Grove kit, as shown with the other components in Figure 1.įor details on installing the Intel® Curie Boards and setting up the software development environment for the Arduino 101* platform, go to. The hardware components used in this project are listed below: We also set up a BLE blood pressure monitoring system to demonstrate the BLE capabilities of the Arduino 101*. We will discuss how to create a BLEservice and communicate with an Android device. Arduino 101* includes on-board Bluetooth LE to enable developers to interact with Bluetooth-enabled devices such as phones and tablets. BLE is designed for small and distinct data transfer, providing a fast connection between client and server and a simple user interface, which makes it ideal for control and monitoring applications. Introductionīluetooth* Low Energy (Bluetooth LE or BLE) is a low-power, short-range wireless communication technology that is ideal for use on the Internet of Things (IoT). 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. ![]()
