Android：我如何连接到隐藏的蓝牙设备？

Question

我有一个隐藏的蓝牙设备，但我知道它的蓝牙MAC地址。

如何使用Android连接到该设备？

Answer 1

从DOC这里：http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html

要获得BluetoothDevice类，使用BluetoothAdapter.getRemoteDevice（字符串） 创建一个代表一个已知的MAC的设备解决

你以后只需连接就像您通过设备发现检索它一样。

我做了这样的：

BluetoothDevice device = mBluetoothAdapter.getRemoteDevice("Some_MAC"); 
     BluetoothSocket tmp = null; 
// Get a BluetoothSocket for a connection with the 
     // given BluetoothDevice 
     try { 
      mBluetoothAdapter.cancelDiscovery(); 
      Method getUuidsMethod = BluetoothAdapter.class.getDeclaredMethod("getUuids", null); 
UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); 
      int sdk = Integer.parseInt(Build.VERSION.SDK); 
      if(sdk >= 10){ 
       //sdk 2.3?? java.io.IOException: Connection refused 
       tmp = device.createInsecureRfcommSocketToServiceRecord(uuid); 
      }else { 
       tmp = device.createRfcommSocketToServiceRecord(uuid); 
      } 
      Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class}); 
      tmp = (BluetoothSocket) m.invoke(device, 1); 
      tmp.connect(); 
} catch (IOException e) { 
      Log.e(TAG, "failed: ", e); 
     } catch (InvocationTargetException e) { 
      e.printStackTrace(); 
     } catch (NoSuchMethodException e) { 
      e.printStackTrace(); 
     } catch (IllegalAccessException e) { 
      e.printStackTrace(); 
     }
