项目介绍

本项目是 PunchThrough 公司提供的 Android Bluetooth Low Energy (BLE) 开发入门项目，旨在帮助开发者快速掌握 Android BLE 开发的基础知识和操作。项目包含了 BLE 设备扫描、连接、服务和特征发现、数据读写、通知和指示的启用与禁用、设备绑定等基本操作的示例代码。

项目快速启动

环境准备

Android StudioAndroid 设备（支持 BLE）

克隆项目

git clone https://github.com/PunchThrough/ble-starter-android.git

打开项目

启动 Android Studio。选择 “Open an existing Android Studio project”。导航到克隆的项目目录并打开。

运行项目

连接 Android 设备。点击 “Run” 按钮，选择你的设备进行安装和运行。

示例代码

以下是一个简单的 BLE 设备扫描示例：




import android.bluetooth.BluetoothAdapter


import android.bluetooth.le.BluetoothLeScanner


import android.bluetooth.le.ScanCallback


import android.bluetooth.le.ScanResult


 


class BleScanner {


    private val bluetoothAdapter: BluetoothAdapter? = BluetoothAdapter.getDefaultAdapter()


    private val bluetoothLeScanner: BluetoothLeScanner? = bluetoothAdapter?.bluetoothLeScanner


 


    fun startScan() {


        bluetoothLeScanner?.startScan(scanCallback)


    }


 


    private val scanCallback = object : ScanCallback() {


        override fun onScanResult(callbackType: Int, result: ScanResult?) {


            result?.device?.let {


                println("Found BLE device: ${it.name} - ${it.address}")


            }


        }


    }


}

应用案例和最佳实践

应用案例

健康监测设备：通过 BLE 连接心率监测器、血压计等设备，实时获取健康数据。智能家居控制：通过 BLE 控制智能灯泡、智能插座等设备。

最佳实践

权限管理：确保在应用中正确请求和处理蓝牙相关的权限。错误处理：在 BLE 操作中加入适当的错误处理逻辑，提高应用的稳定性。性能优化：合理管理 BLE 连接和数据传输，避免资源浪费。

典型生态项目

Android BLE Library：一个开源的 BLE 库，提供了更高级的 BLE 操作接口。BLE Scanner：一个 BLE 设备扫描应用，用于发现和连接附近的 BLE 设备。

通过本教程，你可以快速上手 Android BLE 开发，并了解相关的应用案例和最佳实践。希望你能利用这些知识，开发出优秀的 BLE 应用。
