In a nutshell, the Generic Attribute Profile is a core definition of Bluetooth functionality that is built upon by other specific profiles and services, and these enable devices to co-operate predictably in particular environments.

Android 4.3（API Level 18）开始引入Bluetooth Low Energy（BLE，低功耗蓝牙）的核心功能并提供了相应的 API，应用程序通过这些 API 扫描蓝牙设备、查询 services、读写设备的 characteristics（属性特征）等操作。 In this article, we are going to cover how to setup your own custom GATT service on the Arduino platform and then interact with it using an application running on Windows IoT Core. The project we will create is a BTLE bracelet that has an LED light (NeoPixel) that changes colors based on the communications received over the custom GATT service.

The project we will create is a BTLE bracelet that has an LED light (NeoPixel) that changes colors based on the communications received over the custom GATT service. Primary services are the top level of the GATT tree. Primary services contain characteristics as well as other services (called 'Included' or secondary services).

Basically this part copy from "example code of Bluetooth Le Gatt", refer to " Bluetooth Le Gatt example to link with Arduino/Genuino 101 ". Create a new activity ControlActivity.java. We are writing an Android app for our own peripheral (nRF51-based). We know the handles for all the characteristics. On Android gatt.discoverServices() needs to be called, and wait for onServicesDiscovered(), then getServices(), before the Characteristic object is available.

The roles are not set per device — rather they are determined per transaction (such as request response, indication confirmation, notification). Generic Attribute Profile (GATT)—The GATT profile is a general specification for sending and receiving short pieces of data known as attributes over a BLE link.

In this series, we will learn how to set up both a Bluetooth Low Energy (BLE) Client and Server and demystify the Generic Attribute Profile (GATT) communication process. Part 1 will focus on Server and Client setup and establishing a BLE connection. public final static String EXTRA_DATA = " android.kaviles.bletutorial.Service_BTLE_GATT.EXTRA_DATA "; // Implements callback methods for GATT events that the app cares about.

Devices I have been working on a BLE application with CC2540 (slave) and Nexus 5 ( master). On Android application whenever I am done with physical connection, I discover GATT services, then eventually I can read and write data by using 128 bit&n Chapter 4. GATT (Services and Characteristics) The Generic Attribute Profile ( GATT) establishes in detail how to exchange all profile and user data over a BLE connection. In contrast with GAP … - Selection from Getting Started with Bluet auのAndroid(TM) 技術情報「Bluetooth(R) LE」をご紹介します。 Bluetooth LE GATT (Generic Attribute サービス (Service)、キャラクタリスティック ( Characteristic)、ディスクリプタ (Descriptor) の3つの要素で成り立っています。 ANP Each Service includes a collection of Characteristics to transfer discrete data values between devices.
