使用Nordic芯片的手环OTA（android）

我司现在的手环全部切换到使用nordic方案了，现参照官网上的demo整理一下其固件升级步骤如下

• 第一步:添加依赖

  compile ‘no.nordicsemi.android:dfu:1.0.4’

• 第二步：继承DfuBaseService（不要忘记在清单文件中注册）

public class DfuService extends DfuBaseService {
    @Override
    protected Class<? extends Activity> getNotificationTarget() {
        return null;
    }
}

• 第三步：在升级activity中添加如下代码

 @Override
    protected void onResume() {
        super.onResume();
        DfuServiceListenerHelper.registerProgressListener(this, mDfuProgressListener);
    }

    @Override
    protected void onPause() {
        super.onPause();
        DfuServiceListenerHelper.unregisterProgressListener(this, mDfuProgressListener);
    }

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

        @Override
        public void onDeviceConnected(String deviceAddress) {
            Log.e("dfu", "onDeviceConnected");
        }

        @Override
        public void onDfuProcessStarting(String deviceAddress) {
            Log.e("dfu", "onDfuProcessStarting");
            showProgressDialog();
        }

        @Override
        public void onDfuProcessStarted(String deviceAddress) {
            Log.e("dfu", "onDfuProcessStarted");
        }

        @Override
        public void onEnablingDfuMode(String deviceAddress) {
            Log.e("dfu", "onEnablingDfuMode");
        }

        @Override
        public void onProgressChanged(String deviceAddress, int percent, float speed, float avgSpeed, int currentPart, int partsTotal) {
            Log.e("dfu", "onProgressChanged" + percent);
            progressDialog.setProgress(percent);
        }

        @Override
        public void onFirmwareValidating(String deviceAddress) {
            Log.e("dfu", "onFirmwareValidating");
        }

        @Override
        public void onDeviceDisconnecting(String deviceAddress) {

            Log.e("dfu", "onDeviceDisconnecting");
        }

        @Override
        public void onDeviceDisconnected(String deviceAddress) {
            Log.e("dfu", "onDeviceDisconnected");

        }

        @Override
        public void onDfuCompleted(String deviceAddress) {
            Log.e("dfu", "onDfuCompleted");
            stopDfu();
            progressDialog.dismiss();
            Toast.makeText(mContext, "升级成功", Toast.LENGTH_SHORT).show();

        }

        @Override
        public void onDfuAborted(String deviceAddress) {
            Log.e("dfu", "onDfuAborted");
            progressDialog.dismiss();
            Toast.makeText(mContext, "升级失败，请重新点击升级。", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(String deviceAddress, int error, int errorType, String message) {
            Log.e("dfu", "onError");
            stopDfu();
            progressDialog.dismiss();
            Toast.makeText(mContext, "升级失败，请重新点击升级。", Toast.LENGTH_SHORT).show();
        }
    };

    private void stopDfu() {
        Intent intent = new Intent(this, DfuService.class);
        stopService(intent);
    }

    private void showProgressDialog() {
        progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("正在升级");
        progressDialog.setMessage("请稍等。。。");
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressDialog.setMax(100);
        progressDialog.setCancelable(false);
        progressDialog.show();
    }

• 第四步：手机向手环发送进入OTA状态的命令，成功进入后使用下面代码：

//进入OTA前的mac地址
String mac = SPUtil.getStringValue(AppConstant.SP_KEY_DEVICE_ADDRESS, null);
//进入OTA后的mac地址 （在原mac上加1）
            final String newMac = mac.substring(0, 15) + HexUtil.algorismToHEXString(HexUtil.hexStringToAlgorism(mac.substring(15, 17)) + 1);
//搜索新mac设备
         BleManager.viseBluetooth.setScanTimeout(10000).startScan(new PeriodMacScanCallback(newMac) {
                @Override
                public void scanTimeout() {

                }

                @Override
                public void onFind(BleDevice bleDevice) {
                //传入OTA文件的uri开始空升
                    new DfuServiceInitiator(newMac).setDisableNotification(true)
                            .setZip(uri)
                            .start((getBaseContext()), DfuService.class);
                }
            });
