+# 通用属性协议开发指导示例
+
+### 介绍
+
+通用属性协议是GATT（Generic Attribute）的缩写，它是一种用于在蓝牙低功耗设备之间传输数据的协议，定义了一套通用的属性和服务框架。通过GATT协议，蓝牙设备可以向其他设备提供服务，也可以从其他设备获取服务。
+
+### 场景介绍
+
+主要场景有：
+
+1. 连接server端读取和写入信息
+
+2. server端操作services和通知客户端信息。
+
+### 接口说明
+
+完整的 JS API 说明以及实例代码请参考：[GATT接口](https://gitee.com/openharmony/docs/blob/OpenHarmony-5.0.1-Release/zh-cn/application-dev/reference/apis-connectivity-kit/js-apis-bluetooth-ble.md)
+
+具体接口说明如下表。
+
+| 接口名            | 功能描述       |
+|----------------|------------|
+|connect()|	client端发起连接远端蓝牙低功耗设备。|
+|disconnect()	|client端断开与远端蓝牙低功耗设备的连接。|
+|close()|	关闭客户端功能，注销client在协议栈的注册，调用该接口后GattClientDevice实例将不能再使用。|
+|getDeviceName()|	client获取远端蓝牙低功耗设备名。|
+|getServices()	|client端获取蓝牙低功耗设备的所有服务，即服务发现 。|
+|readCharacteristicValue()|	client端读取蓝牙低功耗设备特定服务的特征值。|
+|readDescriptorValue()	|client端读取蓝牙低功耗设备特定的特征包含的描述符。|
+|writeCharacteristicValue()	|client端向低功耗蓝牙设备写入特定的特征值。|
+|writeDescriptorValue()|	client端向低功耗蓝牙设备特定的描述符写入二进制数据。|
+|getRssiValue()	|client获取远端蓝牙低功耗设备的信号强度 (Received Signal Strength Indication, RSSI)，调用connect接口连接成功后才能使用。|
+|setBLEMtuSize()|	client协商远端蓝牙低功耗设备的最大传输单元（Maximum Transmission Unit, MTU），调用connect接口连接成功后才能使用。|
+|setCharacteristicChangeNotification()|	向服务端发送设置通知此特征值请求。|
+|setCharacteristicChangeIndication()|	向服务端发送设置通知此特征值请求。|
+|on(type: 'BLECharacteristicChange')|	订阅蓝牙低功耗设备的特征值变化事件。需要先调用setNotifyCharacteristicChanged接口才能接收server端的通知。|
+|off(type: 'BLECharacteristicChange')|	取消订阅蓝牙低功耗设备的特征值变化事件。|
+|on(type: 'BLEConnectionStateChange')	|client端订阅蓝牙低功耗设备的连接状态变化事件。|
+|off(type: 'BLEConnectionStateChange')	|取消订阅蓝牙低功耗设备的连接状态变化事件。|
+|on(type: 'BLEMtuChange')	|client端订阅MTU状态变化事件。|
+|off(type: 'BLEMtuChange')	|client端取消订阅MTU状态变化事件。|
+|addService()	|server端添加服务。|
+|removeService()	|删除已添加的服务。|
+|close()	|关闭服务端功能，去注销server在协议栈的注册，调用该接口后GattServer实例将不能再使用。|
+|notifyCharacteristicChanged()|	server端特征值发生变化时，主动通知已连接的client设备。|
+|sendResponse()	|server端回复client端的读写请求。|
+|on(type: 'characteristicRead')	|server端订阅特征值读请求事件。|
+|off(type: 'characteristicRead')|	server端取消订阅特征值读请求事件。|
+|on(type: 'characteristicWrite')|	server端订阅特征值写请求事件。|
+|off(type: 'characteristicWrite')|	server端取消订阅特征值写请求事件。|
+|on(type: 'descriptorRead')	|server端订阅描述符读请求事件。|
+|off(type: 'descriptorRead')	|server端取消订阅描述符读请求事件。|
+|on(type: 'descriptorWrite')	|server端订阅描述符写请求事件。|
+|off(type: 'descriptorWrite')	|server端取消订阅描述符写请求事件。|
+|on(type: 'connectionStateChange')|	server端订阅BLE连接状态变化事件。|
+|off(type: 'connectionStateChange')	|server端取消订阅BLE连接状态变化事件。|
+|on(type: 'BLEMtuChange')	|server端订阅MTU状态变化事件。|
+|off(type: 'BLEMtuChange')|	server端取消订阅MTU状态变化事件。|
+
+
+### 主要场景开发步骤
+
+#### 连接server端读取和写入信息
+
+1. import需要的ble模块。
+2. 开启设备的蓝牙。
+3. 创建gattClient实例对象。
+4. 连接gattServer。
+5. 读取gattServer的特征值和描述符。
+6. 向gattServer写入特征值和描述符。
+7. 断开连接，销毁gattClient实例。
+8. 错误码请参见[蓝牙服务子系统错误码](https://gitee.com/openharmony/docs/blob/OpenHarmony-5.0.1-Release/zh-cn/application-dev/reference/apis-connectivity-kit/errorcode-bluetoothManager.md).
+
+#### server端操作services和通知客户端信息
+
+1. import需要的ble模块。
+2. 创建gattServer实例对象。
+3. 添加services信息。
+4. 移除services信息。
+5. 注销gattServer实例。
+7. 错误码请参见[蓝牙服务子系统错误码](https://gitee.com/openharmony/docs/blob/OpenHarmony-5.0.1-Release/zh-cn/application-dev/reference/apis-connectivity-kit/errorcode-bluetoothManager.md).
