在Android(服务器)和pc(客户端)上的bluecove之间初始化蓝牙连接

在Android(服务器)和pc(客户端)上的bluecove之间初始化蓝牙连接,android,bluetooth,Android,Bluetooth,我知道还有其他相关的话题,但在我的例子中,我希望Android设备将蓝牙连接初始化为服务器。我按照文档的说明编写了服务器: private class AcceptThread implements Runnable { private final BluetoothServerSocket mmServerSocket; public AcceptThread() { BluetoothServerSocket tmp = null; try

我知道还有其他相关的话题,但在我的例子中,我希望Android设备将蓝牙连接初始化为服务器。我按照文档的说明编写了服务器:

private class AcceptThread implements Runnable {
    private final BluetoothServerSocket mmServerSocket;

    public AcceptThread() {

        BluetoothServerSocket tmp = null;
        try {
            tmp = mBluetooth.listenUsingRfcommWithServiceRecord(
                    "myService", mUuid);
        } catch (IOException e) { }
        mmServerSocket = tmp;
    }

    public void run() {
        BluetoothSocket socket = null;
        // Keep listening until exception occurs or a socket is returned
        while (true) {
            try {
                System.out.println("SERVER SOCKET LISTENING");
                socket = mmServerSocket.accept();
            } catch (IOException e) {
                break;
            }
            // If a connection was accepted
            if (socket != null) {
                System.out.println("SIGNAL RECEIVED");
                // Do work to manage the connection (in a separate thread)
                Toast.makeText(getApplicationContext(), "SIGNAL RECEIVED", Toast.LENGTH_LONG).show();
                try {
                    mmServerSocket.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                break;
            }
        }
    }

    /** Will cancel the listening socket, and cause the thread to finish */
    public void cancel() {
        try {
            mmServerSocket.close();
        } catch (IOException e) { }
    }
}
另一方面,我使用bluecove API来发现远程设备和服务

如果(deviceCount我在使用时找到了一些电话服务记录:

    UUID[] uuidSet = new UUID[1];
    uuidSet[0]=new UUID(0x0100);
    int[] attrIds = { 0x0100 };

    System.out.println("\nSearching for service...");
    agent.searchServices(attrIds, uuidSet, remoteDevice, client);
在serviceSearch之后,您将调用lock.notify()两次,请在servicesDiscovered函数中删除它

您还应该浏览服务记录并查找您感兴趣的服务记录。URL将显示btgoep://或btspp://

在for循环中搜索时,使用此代码列出服务名称

 for(int i = 0; i < servRecord.length; i++)
 {
    String url = servRecord[i].getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);
    DataElement serviceName = srs[i].getAttributeValue(0x0100);
    if (serviceName != null) {
       System.out.println("service " + serviceName.getValue() + " found " + url);
    } else {
       System.out.println("service found " + url);
    }
for(int i=0;i
我有一个确切的问题,android api似乎没有向SDP注册ServiceRecord,以便Bluecove api可以找到它。 无论我使用什么UUID,它都只会找到我的手机默认注册的UUID,即音频网关和电话簿OBEX推送等

编辑--- 我也遇到了同样的问题,但我意识到我实际上还没有调用ListenusingSecureRfcomSocket。然后它没有注册服务记录。 但在那之后,一切都很好
