我正在尝试使用 Windows 上的 Bluecove 将数据从 android(使用其 SDK 中的 API)发送到 PC,作为最后一个服务器。
我可以让 android 连接到服务器,但是当我写入套接字的输出流时,服务器上没有任何反应。我覆盖了 onPut 方法,但从未调用它。
代码如下,如果有人能帮助我,我将不胜感激:
安卓
public class BluetoothWorker {
private static UUID generalUuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
private static BluetoothSocket socket;
private static BluetoothSocket getBluetoothSocket(){
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
mBluetoothAdapter.cancelDiscovery();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
// If there are paired devices
if (pairedDevices.size() > 0) {
// Loop through paired devices
for (BluetoothDevice device : pairedDevices) {
// Add the name and address to an array adapter to show in a ListView
if(device.getName().equalsIgnoreCase(("MIGUEL-PC"))){
try {
return device.createRfcommSocketToServiceRecord(generalUuid);
} catch (IOException e) {
return null;
}
}
}
}
return null;
}
public static boolean sendData(String status){
socket = getBluetoothSocket();
try {
socket.connect();
} catch (IOException e) {
// TODO Auto-generated catch block
socket = null;
}
if(socket != null){
try {
socket.getOutputStream().write(status.getBytes());
socket.getOutputStream().flush();
socket.close();
return true;
} catch (IOException e) {
socket = null;
return false;
}
}else{
return false;
}
}
}
电脑代码
public class AISHIntegrationBTBridge {
static final String serverUUID = "0000110100001000800000805F9B34FB";
public static void main(String[] args) throws IOException {
LocalDevice.getLocalDevice().setDiscoverable(DiscoveryAgent.GIAC);
SessionNotifier serverConnection = (SessionNotifier) Connector.open("btgoep://localhost:"
+ serverUUID + ";name=ObexExample");
int count = 0;
while(count < 2) {
RequestHandler handler = new RequestHandler();
serverConnection.acceptAndOpen(handler);
System.out.println("Received OBEX connection " + (++count));
}
}
private static class RequestHandler extends ServerRequestHandler {
public int onPut(Operation op) {
try {
HeaderSet hs = op.getReceivedHeaders();
String name = (String) hs.getHeader(HeaderSet.NAME);
if (name != null) {
System.out.println("put name:" + name);
}
InputStream is = op.openInputStream();
StringBuffer buf = new StringBuffer();
int data;
while ((data = is.read()) != -1) {
buf.append((char) data);
}
System.out.println("got:" + buf.toString());
op.close();
return ResponseCodes.OBEX_HTTP_OK;
} catch (IOException e) {
e.printStackTrace();
return ResponseCodes.OBEX_HTTP_UNAVAILABLE;
}
}
}
}
最佳答案
两年前我做过类似的事情。
对于 Android,我的代码与您的略有不同:
BluetoothSocket socket = Device.createRfcommSocketToServiceRecord(device_UUID);
socket.connect();
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
dos.writeChar('x'); // for example
socket.close();
我使用 DataOutputStream
向 PC 发送数据。不过肯定没关系,仅供大家引用。
对于电脑,
LocalDevice localDevice = LocalDevice.getLocalDevice();
localDevice.setDiscoverable(DiscoveryAgent.GIAC); // Advertising the service
String url = "btspp://localhost:" + device_UUID + ";name=BlueToothServer";
StreamConnectionNotifier server = (StreamConnectionNotifier) Connector.open(url);
StreamConnection connection = server.acceptAndOpen(); // Wait until client connects
//=== At this point, two devices should be connected ===//
DataInputStream dis = connection.openDataInputStream();
char c;
while (true) {
c = dis.readChar();
if (c == 'x')
break;
}
connection.close();
我不确定上面的代码今天是否仍然有效,因为这是 2 年前完成的。 BlueCove API 可能发生了很大变化。但无论如何,这些代码对我有用。希望这对您有所帮助。
需要注意的是,为了使用 BlueCove,我必须在我的 PC 上卸载 Toshiba 蓝牙驱动程序并重新安装 Microsoft 的驱动程序。否则,它不会工作。 (不过最新版本的BlueCove可能已经支持不同的驱动,如有不妥请指正。)
