1、项目介绍

BLE Peripheral Simulator 是一个 Android 应用程序，旨在帮助开发者在没有 BLE 外设设备的情况下尝试 Web Bluetooth 的新功能。该应用允许开发者模拟三种服务：电池服务、心率服务和健康温度计服务。开发者可以使用 Web Bluetooth 的新功能连接到应用，进行特征的读写、订阅特征变化的通知以及读写描述符。

2、项目快速启动

克隆项目

首先，克隆项目到本地：

git clone https://github.com/WebBluetoothCG/ble-test-peripheral-android.git

导入项目

使用 Android Studio 打开项目：

打开 Android Studio。选择 Open an existing Android Studio project。导航到克隆的项目目录并选择 ble-test-peripheral-android 文件夹。

构建和运行

连接 Android 设备或启动模拟器。点击 Run 按钮（绿色三角形）来构建和运行应用。

示例代码

以下是一个简单的示例代码，展示如何在应用中模拟 BLE 外设：




import android.bluetooth.BluetoothGattCharacteristic;


import android.bluetooth.BluetoothGattService;


import android.os.Bundle;


import android.support.v7.app.AppCompatActivity;


import java.util.UUID;


 


public class MainActivity extends AppCompatActivity {


    @Override


    protected void onCreate(Bundle savedInstanceState) {


        super.onCreate(savedInstanceState);


        setContentView(R.layout.activity_main);


 


        // 创建一个心率服务


        BluetoothGattService heartRateService = new BluetoothGattService(


                UUID.fromString("0000180D-0000-1000-8000-00805F9B34FB"),


                BluetoothGattService.SERVICE_TYPE_PRIMARY);


 


        // 添加心率特征


        BluetoothGattCharacteristic heartRateCharacteristic = new BluetoothGattCharacteristic(


                UUID.fromString("00002A37-0000-1000-8000-00805F9B34FB"),


                BluetoothGattCharacteristic.PROPERTY_NOTIFY,


                BluetoothGattCharacteristic.PERMISSION_READ);


 


        heartRateService.addCharacteristic(heartRateCharacteristic);


    }


}

3、应用案例和最佳实践

应用案例

健康监测应用：使用 BLE Peripheral Simulator 模拟心率监测器，开发一个健康监测应用，实时显示心率数据。智能家居控制：模拟智能家居设备（如温度计），开发一个控制应用，远程读取和设置设备状态。

最佳实践

模块化设计：将不同的 BLE 服务和特征封装成模块，便于管理和扩展。错误处理：在连接、读写特征时添加错误处理逻辑，提高应用的稳定性。性能优化：优化 BLE 通信的频率和数据量，减少功耗和延迟。

4、典型生态项目

Web Bluetooth API：与 BLE Peripheral Simulator 配合使用，实现网页与 BLE 设备的交互。Android BLE 库：如 Nordic Semiconductor 的 BLE 库，提供更丰富的 BLE 功能和工具。IoT 平台：如 Google Cloud IoT Core，用于管理和分析从 BLE 设备收集的数据。

通过以上教程，您可以快速上手 BLE Peripheral Simulator 项目，并了解其在实际应用中的使用方法和最佳实践。
