C#. [Android.Runtime.Register ("addService", " (Landroid/bluetooth/BluetoothGattService;)Z", "")] public bool AddService (Android.Bluetooth.BluetoothGattService service); In most BLE scenarios, Android app is a client (GATT Client). But one can also use Android as a GATT Server. There are use-cases where running a GATT Server on Android can be useful. For example let’s say you want a desktop app to display SMS notifications.

In proper central mode the nrf would do the scanning and connecting and android would be the peripheral and just host the gatt server (with Alert notification service + necessary characteristics) and advertise. However as the nrf needs to be scanned by the android device, I first connect the device via regular gatt.

Android Nexus 4: Minimum Connection Interval of 7.5 mSecs – Packets per connection Interval: 6 – Throughput: 16,000 Bytes/Sec Android手机间通过蓝牙方式进行通信，有两种常见的方式，一种是socket方式，另一种是通过Gatt Server（Android 5.0以后）通信，socket方式最为简单，但是很多低功耗的蓝牙设备，如单片机上的蓝牙模块可能不支持。 BLE蓝牙知识---GATT Profile 一. 引言. 现在低功耗蓝牙（BLE）连接都是建立在GATT（Generic Attribute Profile）协议之上。GATT是一个在蓝牙连接之上的发送和接收很短的数据段的通用规范，这些很短的数据段被称为属性（Attribute）。 BLE server to send Battery level data to Mobile Phone using GATT Service . 3. BLE client to scan for BLE devices and act as beacon. We have already covered the first article; in this article we will learn how to make the ESP32 BLE to work as a server and use the GATT Service to send battery level information.

Once two devices are paired each device can act as both a GATT Server and a GATT Client. This is a GATT server demo and its tutorial. This demo creates a GATT service by adding attributes one by one as defined by Bluedroid. The recommended method of adding attributes is presented in example above. The GATT protocol provides some commands for using in the client-server model.

BluetoothGattServer is a proxy object for controlling the Bluetooth Service via IPC. The GATT Server has Custom Service and Characteristic with unique UUIDs. How can I pinpoint connect to this server and send some text? The minimum SDK is 21, and target SDK is 24, so old BluetoothLE Scanning method is deprecated, and now I need to use BluetoothLEScanner. android bluetooth bluetooth-lowenergy android-bluetooth gatt The Bluetooth GATT (Generic Attribute Profile) is the foundation for the design of any BLE system and defines the way a smartphone application (or any central device) interacts with the end-device (the peripheral device).
