求解决，使用native调用原生代码，实现蓝牙广播报错问题

/ 开启蓝牙广播

  var mBluetoothLeAdvertiser=plus.android.importClass("android.bluetooth.le.BluetoothLeAdvertiser");
  var mAdvertiseSettings=plus.android.importClass("android.bluetooth.le.AdvertiseSettings");

  var main = plus.android.runtimeMainActivity();
  var Context = plus.android.importClass("android.content.Context");
  var BManager = main.getSystemService(Context.BLUETOOTH_SERVICE);
  plus.android.importClass(BManager);//引入相关的method函数
  var BAdapter = BManager.getAdapter();
  plus.android.importClass(BAdapter);//引入相关的method函数，这样之后才会有isEnabled函数支持

  var mBluetoothLeAdvertiser1=BAdapter.getBluetoothLeAdvertiser();

  console.log("进入openpublic1");
  var settingsBuilder=new mAdvertiseSettings.Builder();
  //AdvertiseSettings.Builder settingsBuilder = new AdvertiseSettings.Builder();
  settingsBuilder.setAdvertiseMode(mAdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY);

  var uuid=['00001101-0000-1000-8000-00805F9B34FB','00011101-0000-1000-8000-00805F9B34FB','00001121-0000-1000-8000-00805F9B34FB'];

  var sendDatas=[1,2];

  dataBuilder.addManufacturerData(1,sendDatas);
  var advertiseData=dataBuilder.build();
  console.log("进入openpublic3");

  var mAdvertiseCallback;
  console.log("进入openpublic4");
  mAdvertiseCallback = plus.android.implements('android.bluetooth.le.AdvertiseCallback', {
  onStartSuccess: function(settingsInEffect) { //实现onStartSuccess回调函数

      console.log("success"); //获取action    
  
  }  ,  
  onStartFailure:function(errorCode) { //实现onStartFailure回调函数    
  
   console.log("error"+errorCode);  
  
  }    

  });

  console.log("进入openpublic5"+setting+"``"+advertiseData+""+mAdvertiseCallback);
  mBluetoothLeAdvertiser1.startAdvertising(setting, advertiseData, mAdvertiseCallback);

  outSet('开启蓝牙广播：');

}

其他方法调用正常，

执行到最后startAdvertising 方法报错。
