Android 连接Acer Iconia B1上的蓝牙时出错

Android 连接Acer Iconia B1上的蓝牙时出错,android,bluetooth,Android,Bluetooth,谢谢你看我的问题。我在Arduino上使用RN42或HC05蓝牙模块开发了一个蓝牙应用程序。这将是一个应用程序,我希望放在游戏商店。除了Acer Iconia B1(我们想要使用的那款)之外,该应用程序似乎在我检查过的大多数平板电脑上都运行良好 我从logCat得到的错误是: 03-08 21:35:10.972: I/BluetoothSocket_MTK(2712): [JSR82] Bluetooth Socket Constructor 03-08 21:35:10.972: I/Blu

谢谢你看我的问题。我在Arduino上使用RN42或HC05蓝牙模块开发了一个蓝牙应用程序。这将是一个应用程序,我希望放在游戏商店。除了Acer Iconia B1(我们想要使用的那款)之外,该应用程序似乎在我检查过的大多数平板电脑上都运行良好

我从logCat得到的错误是:

我初始化蓝牙的代码:

   public boolean connectBluetooth() throws Exception, Exception{
        BT = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(MacAddress);
        m = BT.getClass().getMethod("createInsecureRfcommSocket", new Class[] { int.class });
        mBluetoothAdapter.enable();
        sock = (BluetoothSocket) m.invoke(BT, 1);
        Log.d("Bluetooth", "++++ Connecting to " + MacAddress);
        sock.connect();
        Log.d("Bluetooth", "++++ Connected");
        connected = true;
        in = sock.getInputStream();
        return true;
    }

我感谢你的帮助

很可能您要求的是Acer Iconia B1中没有的功能

平板电脑要么与bluetooth 2.1(第一个答案)不兼容,要么就是无法连接到“A2DP立体声耳机”以外的设备(最后一篇文章)
