Android的蓝牙COM端口 [英] Android Bluetooth COM port
问题描述
我已经花了一些时间研究Android的使用,旨在通过蓝牙COM端口的PC上进行通信的蓝牙设备进行通信的能力。我一直没能找到一个明确的答案,所以我想我会问这里。我要确保这是可能与Android。
I have spent some time researching Android's ability to communicate with bluetooth devices that are designed to communicate over a Bluetooth COM port on a PC. I haven't been able to find a definitive answer, so I thought I'd ask here. I want to make sure that this is possible with Android.
我是新来的蓝牙通信,但我迄今所做的研究使我RFCOMM这在一定程度听起来像我想要的东西。不幸的是,我还无法确认这是事实可能。
I am new to Bluetooth communications, but the research I've done so far lead me to RFCOMM which somewhat sounded like what I wanted. Unfortunately, I'm still unable to confirm that this is in fact possible.
任何帮助/资源将大大AP preciated。
Any help/resources on this would be greatly appreciated.
推荐答案
是的,Android的可以连接到PC上的蓝牙COM端口。我目前正在开发这样的应用程序。这里是一个code例子(ITE需要蓝牙权限TE在Manifest.xml文件中设置):
Yes, Android can connect to Bluetooth COM ports on PC's. I am currently developing such an application. Here is a code example (Ite requires the bluetooth permissions te be set in the Manifest.xml file):
<uses-permission android:name="android.permission.BLUETOOTH" />
Java的:
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) {}
