Android藍牙COM端口

Question

我花了一些時間研究Android與藍牙設備通信的能力，藍牙設備旨在通過PC上的藍牙COM端口進行通信。我一直無法找到明確的答案，所以我想我會在這裏問。我想確保這可能與Android。

我是藍牙通信的新手，但迄今爲止我所做的研究讓我感到RFCOMM有點像我想要的。不幸的是，我仍然無法證實這實際上是可能的。

任何幫助/資源將不勝感激。

是的，Android可以連接到PC上的藍牙COM端口。我目前正在開發這樣的應用程序。下面是一個代碼示例（ITE需要藍牙權限TE在Manifest.xml文件中設置）：

<uses-permission android:name="android.permission.BLUETOOTH" /> 

的Java：

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter(); 
if (adapter == null) { 
    // Device does not support Bluetooth 
    finish(); //exit 
} 

if (!adapter.isEnabled()) { 
//make sure the device's bluetooth is enabled 
    Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); 
    startActivityForResult(enableBluetooth, REQUEST_ENABLE_BT); 
} 

final UUID SERIAL_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); //UUID for serial connection 
mac = "00:15:83:3D:0A:57"; //my laptop's mac adress 
device = adapter.getRemoteDevice(mac); //get remote device by mac, we assume these two devices are already paired 


// Get a BluetoothSocket to connect with the given BluetoothDevice 
BluetoothSocket socket = null; 
OutputStream out = null; 
try { 
    socket = device.createRfcommSocketToServiceRecord(SERIAL_UUID); 
} catch (IOException e) {} 

try {   
    socket.connect(); 
    out = socket.getOutputStream(); 
    //now you can use out to send output via out.write 
} catch (IOException e) {}
