blueCove进行蓝牙传输数据

需要bluecove.jar
下载地址：
bluecove-2.1.0.jar
bluecove-2.1.1-SNAPSHOT(x64).jar
作为服务端：

public class BluetoothJavaServer {private StreamConnectionNotifier mStreamConnectionNotifier = null;private StreamConnection mStreamConnection = null;public static void main(String[] args) {new BluetoothJavaServer();}public BluetoothJavaServer() {try {// 服务器端的UUID必须和手机端的UUID相一致。手机端的UUID需要去掉中间的-分割符。mStreamConnectionNotifier = (StreamConnectionNotifier) Connector.open("btspp://localhost:0000110100001000800000805F9B34FB");} catch (Exception e) {e.printStackTrace();}// 开启线程读写蓝牙上接收和发送的数据。new Thread(new Runnable() {@Overridepublic void run() {try {System.out.println("服务器端开始监听...");while (true) {mStreamConnection = mStreamConnectionNotifier.acceptAndOpen();System.out.println("接受连接");InputStream is = mStreamConnection.openInputStream();byte[] buffer = new byte[1024];System.out.println("开始读数据...");// 读数据。int len=0;while ((len=is.read(buffer)) != -1) {String s = new String(buffer,0,len);System.out.println(s);}is.close();mStreamConnection.close();}} catch (Exception e) {e.printStackTrace();}}}).start();}
}

作为客户端：
分为3步：

发现蓝牙设备（对于已配对设备可跳过扫描，直接获取已配对设备即可）
查询符合条件的设备
传输数据

1.扫描蓝牙设备代码：
扫描的设备存放在devicesDiscovered中

public class RemoteDeviceDiscovery {public static final Vector/*<RemoteDevice>*/ devicesDiscovered = new Vector();public static void main(String[] args) throws IOException, InterruptedException {final Object inquiryCompletedEvent = new Object();devicesDiscovered.clear();DiscoveryListener listener = new DiscoveryListener() {public void deviceDiscovered(RemoteDevice btDevice, DeviceClass cod) {System.out.println("Device " + btDevice.getBluetoothAddress() + " found");devicesDiscovered.addElement(btDevice);try {System.out.println("     name " + btDevice.getFriendlyName(false));} catch (IOException cantGetDeviceName) {}}public void inquiryCompleted(int discType) {System.out.println("Device Inquiry completed!");synchronized(inquiryCompletedEvent){inquiryCompletedEvent.notifyAll();}}public void serviceSearchCompleted(int transID, int respCode) {}public void servicesDiscovered(int transID, ServiceRecord[] servRecord) {}};synchronized(inquiryCompletedEvent) {boolean started = LocalDevice.getLocalDevice().getDiscoveryAgent().startInquiry(DiscoveryAgent.GIAC, listener);if (started) {System.out.println("wait for device inquiry to complete...");inquiryCompletedEvent.wait();System.out.println(devicesDiscovered.size() +  " device(s) found");}}}
}

获取已配对设备

//获取已配对设备 DiscoveryAgent.PREKNOWN表示已配对的所有设备;
//DiscoveryAgent.CACHED表示配对已连接设备
RemoteDevice[] remoteDevices = LocalDevice.getLocalDevice().getDiscoveryAgent().retrieveDevices(DiscoveryAgent.CACHED);

2.查询符合条件的设备：通过uuid在设备列表中查询目标设备，查询到的设备放在serviceFound中

public class ServicesSearch {private static final UUID OBEX_OBJECT_PUSH = new UUID("0000110100001000800000805F9B34FB",false);public static final Vector<String> serviceFound = new Vector();public static void main(String[] args) throws IOException, InterruptedException {// First run RemoteDeviceDiscovery and use discoved device// RemoteDeviceDiscovery.main(null);serviceFound.clear();UUID serviceUUID = OBEX_OBJECT_PUSH;if ((args != null) && (args.length > 0)) {serviceUUID = new UUID(args[0], false);}final Object serviceSearchCompletedEvent = new Object();DiscoveryListener listener = new DiscoveryListener() {public void deviceDiscovered(RemoteDevice btDevice, DeviceClass cod) {}public void inquiryCompleted(int discType) {}public void servicesDiscovered(int transID, ServiceRecord[] servRecord) {for (int i = 0; i < servRecord.length; i++) {String url = servRecord[i].getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);if (url == null) {continue;}serviceFound.add(url);DataElement serviceName = servRecord[i].getAttributeValue(0x0100);if (serviceName != null) {System.out.println("service " + serviceName.getValue() + " found " + url);} else {System.out.println("service found " + url);}}}public void serviceSearchCompleted(int transID, int respCode) {System.out.println("service search completed!");synchronized(serviceSearchCompletedEvent){serviceSearchCompletedEvent.notifyAll();}}};UUID[] searchUuidSet = new UUID[] { serviceUUID };int[] attrIDs =  new int[] {0x0100 // Service name};for(Enumeration en = RemoteDeviceDiscovery.devicesDiscovered.elements(); en.hasMoreElements(); ) {RemoteDevice btDevice = (RemoteDevice)en.nextElement();synchronized(serviceSearchCompletedEvent) {System.out.println("search services on " + btDevice.getBluetoothAddress() + " " + btDevice.getFriendlyName(false));LocalDevice.getLocalDevice().getDiscoveryAgent().searchServices(attrIDs, searchUuidSet, btDevice, listener);serviceSearchCompletedEvent.wait();}}}}

3.传输数据，通过输出流传输数据

public class BluetoothClient {private static String serverUUID = "0000110100001000800000805F9B34FB";private static String serverURL = null;public static void main(String[] args) throws Exception {SystemTray systemTray = SystemTray.getSystemTray();ImageIcon imageIcon = new ImageIcon(BluetoothClient.class.getResource("/icon/1.png"));TrayIcon trayIcon = new TrayIcon(imageIcon.getImage(),"");systemTray.add(trayIcon);}public static Vector<String> getServerURL(String serverUUID) throws Exception {ServicesSearch.main(new String[] { serverUUID });if (ServicesSearch.serviceFound.size() == 0) {return new Vector<String>();}return ServicesSearch.serviceFound;}public static OutputStream getOutputstream(String serverURL) throws Exception {StreamConnection connection = (StreamConnection) Connector.open(serverURL);return connection.openOutputStream();}
}
