Android蓝牙固件升级 DFU-OTA 固件升级

1、添加依赖包：

implementation 'no.nordicsemi.android:dfu:1.11.0'

2、DfuService类继承 DfuBaseService

package com.example.ycblesdkdemo.dfu;

import android.app.Activity;

import android.os.Bundle;

import androidx.annotation.Nullable;

import androidx.appcompat.app.AppCompatActivity;

import no.nordicsemi.android.dfu.DfuBaseService;

public class DfuService extends DfuBaseService {

    @Override

    protected Class<? extends Activity> getNotificationTarget() {

        return NotificationActivity.class;

    }

    @Override

    protected boolean isDebug() {

        return true;

    }

    @Override

    public void onDestroy() {

        super.onDestroy();

    }

}

 class NotificationActivity extends AppCompatActivity {

    @Override

    protected void onCreate(@Nullable Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

//        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);

//        }

//

//        finish();

    }

}

3、添加工具类 DfuUtils

package com.example.ycblesdkdemo.dfu;

import android.annotation.SuppressLint;

import android.app.ActivityManager;

import android.content.Context;

import android.content.Intent;

import android.os.Build;

import android.util.Log;

import no.nordicsemi.android.dfu.DfuProgressListener;

import no.nordicsemi.android.dfu.DfuServiceController;

import no.nordicsemi.android.dfu.DfuServiceInitiator;

import no.nordicsemi.android.dfu.DfuServiceListenerHelper;

import static android.content.Context.ACTIVITY_SERVICE;

/**

 * Blog:https://www.cnblogs.com/finn21/

 * @date :2021/9/23 11:45

 * @description:

public class DfuUtils {

    private static DfuUtils dfuUtils;

    private DfuServiceController serviceController;

    private DfuServiceInitiator starter;

    public static DfuUtils getInstance() {

        if (dfuUtils == null) {

            synchronized (DfuUtils.class) {

                if (dfuUtils == null) {

                    dfuUtils = new DfuUtils();

                }

            }

        }

        return dfuUtils;

    }

    public void setmDfuProgressListener(Context mContext, DfuProgressListener dfuProgressListener) {

        DfuServiceListenerHelper.registerProgressListener(mContext, dfuProgressListener); //监听升级进度

    }

    //开始升级

    /**

     *

     * @param mContext

     * @param deviceMac  蓝牙mAC地址

     * @param deviceName 蓝牙名称

     * @param mDeviceZipFilePath  要升级的固件的地址

     */

    public void startUpdate(Context mContext, String deviceMac, String deviceName, String mDeviceZipFilePath) {

        if (mDeviceZipFilePath == null) {

//            ToastUtils.showShort(mContext, mContext.getResources().getString(R.string.update_no_path));

            Log.e("升级","开始升级");

            return;

        }

        //闪退问题解决 兼容   启动前台通知的问题，因为这个库在升级的时候会在通知栏显示进度，

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            DfuServiceInitiator.createDfuNotificationChannel(mContext);

        }

        starter = new DfuServiceInitiator(deviceMac)

                .setDeviceName(deviceName)//设备名称

                .setKeepBond(false)//保持设备绑定 官方demo为false

                .setForceDfu(false)

                .setPacketsReceiptNotificationsEnabled(false)

                .setPacketsReceiptNotificationsValue(12)

                .setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true);//官方ndemo为true

        // If you want to have experimental buttonless DFU feature supported call additionally:

        starter.setZip(mDeviceZipFilePath);

        serviceController = starter.start(mContext, DfuService.class); //启动升级服务

    }

    //暂停升级

    public void pauseDevice(Context mContext) {

        if (isDfuServiceRunning(mContext) && serviceController != null) {

            serviceController.pause();

        }

    }

    //销毁升级

    public void abortDevice(Context mContext) {

        if (isDfuServiceRunning(mContext) && serviceController != null) {

            serviceController.abort();

        }

    }

    /**

     * 判断dfu状态

     *

     * @return

     */

    @SuppressLint("NewApi")

    private boolean isDfuServiceRunning(Context mContext) {

        final ActivityManager manager = (ActivityManager) mContext.getSystemService(ACTIVITY_SERVICE);

        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {

            if (DfuService.class.getName().equals(service.service.getClassName())) {

                return true;

            }

        }

        return false;

    }

    //退出 dfu

    public void dispose(Context mContext,DfuProgressListener dfuProgressListener) {

        DfuServiceListenerHelper.unregisterProgressListener(mContext, dfuProgressListener);

        if (isDfuServiceRunning(mContext)) {

            if (serviceController != null) {

                serviceController.abort();

                mContext.stopService(new Intent(mContext, DfuService.class));

            }

        }

        if (starter != null) {

            starter = null;

        }

        if (serviceController != null) {

            serviceController = null;

        }

    }

}

4、当前Activity 继承 DfuProgressListener 实现方法如下

    //实现DfuProgressListener的回调函数

    @Override

    public void onDeviceConnecting(String deviceAddress) {

    }

    @Override

    public void onDeviceConnected(String deviceAddress) {

    }

    @Override

    public void onDfuProcessStarting(String deviceAddress) {

    }

    @Override

    public void onDfuProcessStarted(String deviceAddress) {

    }

    @Override

    public void onEnablingDfuMode(String deviceAddress) {

    }

    @Override

    public void onProgressChanged(String deviceAddress, int percent, float speed, float avgSpeed, int currentPart, int partsTotal) {

        //percent 是进度 在这里可以展示进度条

        Log.e("升级",deviceAddress+"升级进度 "+percent+"===="+speed+"===="+avgSpeed+"===="+currentPart+"===="+partsTotal);

    }

    @Override

    public void onFirmwareValidating(String deviceAddress) {

    }

    @Override

    public void onDeviceDisconnecting(String deviceAddress) {

    }

    @Override

    public void onDeviceDisconnected(String deviceAddress) {

    }

    @Override

    public void onDfuCompleted(String deviceAddress) {

        //升级成功

        Log.e("升级",deviceAddress+"升级成功");

    }

    @Override

    public void onDfuAborted(String deviceAddress) {

        //升级流产，失败

        // let's wait a bit until we cancel the notification. When canceled immediately it will be recreated by service again.

        //升级错误

        Log.e("升级",deviceAddress+"升级失败");

    }

    @Override

    public void onError(String deviceAddress, int error, int errorType, String message) {

        //升级错误

        Log.e("升级",deviceAddress+"升级错误"+error+"===="+errorType+"===="+message);

    }

5、开始，退出升级调用：

 private void DfuLoad(){//开始升级

      //先注册进度以及升级状态回调

      DfuUtils.getInstance().setmDfuProgressListener(mContext,this);//升级状态回调

//开始正式升级

      DfuUtils.getInstance().startUpdate(mContext,macVal,localName,filepathval);

  }

    private void OutDfuLoad(){//退出升级

        DfuUtils.getInstance().dispose(mContext,this);//升级状态回调

    }

加油！
