I. OverviewThe Generic Attribute profile (GATT) defines a service framework using theAttribute Protocol. This framework defines Proceduresand formats of servicesand their characteristics. The proceduresdefined include discovering, reading,Writing, notifying and indicating characteristics, as well asconfiguring theBroadcast of characteristics.Two.

information between two Bluetooth devices, the main side pre-stored from the terminal device PIN code, address, etc., the two ends of the device power-on-build chain, transparent serial transmission, without peripheral circuit intervention. The slave device can be set to two types, one is silent state, that can only communicate with the specified master, not be found by other Bluetooth devices, and the development status can be found either by the designated master or by other Bluetooth devices

A rough explanation of the communication between Android and Bluetooth Ble, android Bluetooth ble First, briefly introduce ble features (Note: Bluetooth 4.0 is only supported by Android 4.3 or later) 1. BLE (Bluetooth Low Energy) is the core profile of Bluetooth 4.0. It features fast search, fast connection, ultra-Low

Earlier this year, Microsoft confirmed that it would bring the GATT Server APIs for WIN10 mobile devices, later this year. GATT agreements are important for wearable equipment services, such as smart bracelet, smart watch, etc. Microsoft employee Clint Rutkas at the end of September that the Bluetooth team is working to add the GATT Server APIs to the WINDOWS

Recently, with the popularity of smart wearable equipment, intelligent medical care and intelligent home, Bluetooth development is very important in moving. Because of the company's needs, we studied the Bluetooth 4.0 application in Android. Here are some of my summaries. 1. Let me introduce some of the nouns in Bluetooth 4.0:(1), GATT (gneric attibute profile) Through BLE connection, reads and writes th

Many developers are developing BLE peripheral devices, which often contain the device Information Service (DIS) services that this article is anxious to introduce , It is a very good way for the maker of equipment, software and hardware version control, production information disclosure. It is therefore recommended that you include this Standard service defined by the SIG at the time of development. On the bluetooth SIG official website, check the De

Introduction GATT (Generic Attribute profile) describes a service framework that uses ATTThe framework defines the process (Procedure) and format of the service (Server) and service properties (characteristic)Procedure defines characteristic discovery, read, write, notification (notifing), instructions (indicating)and configure the characteristic broadcast GATT can be used by application or other profil

I. Introduction to ANDROID low power Bluetooth (BLE) APIfrom Android 4.3 (API 18) to support the core function of Bluetooth low power, ble, ble Bluetooth protocol is the GATT protocol, BLE related classes are not many, There are several classes in the Android.bluetooth pack

Android: Bluetooth 4.0-BLE-Summary = 1.0, android4.0-ble-Requirement: BLE connection and communication (currently-enable device-search device-connect device) resources: some demos and official documents from the network : 1-BLE is an API provided by Android4.3 or later-some conceptual things are necessary. Currently,

device runs properly and needs to determine if the device supports BLE feature when the code is running: if (! Getpackagemanager (). Hassystemfeature (Packagemanager.feature_bluetooth_le)) { 　　// does not support ble finish ();}(1) Implement the BluetoothAdapter.LeScanCallback interface, the BLE device search results will be returned through this callback

Since Android 4.3, BLE (Bluetooth low energy) has been supported on the Android platform. However, there are few BLE applications available on Android, especially in Chinese applications, and hopefully this article will help developers interested in developing BLE applications. This article is mainly to the existing andriod B
