dfu升级适用于nordic nRF51 nRF52 的系统,github上提供了相关升级的库 https://github.com/NordicSemiconductor/Android-DFU-Library 支持 Android 4.3+
gradle配置如下:
implementation 'no.nordicsemi.android:dfu:1.8.1'
在使用前请先配置好BLE的相关权限以及动态权限 读写权限 定位等可以使用EasyPermission配置
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED" />
第一步 我们创建一个service集成DfuBaseService
public class DfuService extends DfuBaseService { public DfuService() { } @Override protected Class<? extends Activity> getNotificationTarget() { return NotificationActivity.class; } @Override public IBinder onBind(Intent intent) { // TODO: Return the communication channel to the service. throw new UnsupportedOperationException("Not yet implemented"); } }
第二步 创建一个NotificationActivity
public class NotificationActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // If this activity is the root activity of the task, the app is not running if (isTaskRoot()) { // Start the app before finishing final Intent intent = new Intent(this, UpdateZipActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.putExtras(getIntent().getExtras()); // copy all extras startActivity(intent); } // Now finish, which will drop you to the activity at which you were at the top of the task stack finish(); } }
其中UpdateZipActivity即为处理升级业务的界面
在这里要根据你的业务需求来,可以把升级包打包在apk里,也可以做成下载后升级的情况
如果是打包在apk里可以按下面做,如果你是下载的情况只需要改starter.setZip(uri, path); 传入文件uri和路径即可
private DfuServiceInitiator starter; starter = new DfuServiceInitiator(mac).setDeviceName("Smart Lock").setKeepBond(false).setPacketsReceiptNotificationsEnabled(true).setPacketsReceiptNotificationsValue(10); // If you want to have experimental buttonless DFU feature supported call additionally: starter.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true); starter.setZip(R.raw.update24); //setDeviceName为设备过滤条件 setzip传入raw文件的路径即可
@Override
protected void onResume() {
DfuServiceListenerHelper.registerProgressListener(this, mDfuProgressListener); //监听升级进度
starter.start(this, DfuService.class); //启动升级服务
}
/**

private final DfuProgressListener mDfuProgressListener = new DfuProgressListener() {
@Override
public void onDeviceConnecting(String deviceAddress) {
Log.i("dfu", "onDeviceConnecting");
