Question

我是蓝牙开发的新手。我已经开发了一个Android应用，即 rfcomm服务器：

public AcceptThread() {
        // Use a temporary object that is later assigned to mmServerSocket,
        // because mmServerSocket is final
        BluetoothServerSocket tmp = null;
        try {
            // MY_UUID is the app's UUID string, also used by the client code
            tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME, MY_UUID);
        } catch (IOException e) {
        }
        mmServerSocket = tmp;
    }

    public void run() {
        BluetoothSocket socket = null;
        // Keep listening until exception occurs or a socket is returned
        while (true) {
            try {
                Log.i("BluetoothServer","Connecting...");
                socket = mmServerSocket.accept();
            } catch (IOException e) {
                break;
            }
            Log.i("BluetoothServer","Connected");
            // If a connection was accepted
            if (socket != null) {
                Log.i("BluetoothServer","Connected OK");
                // Do work to manage the connection (in a separate thread)
                manageConnectedSocket(socket);
                try {
                    mmServerSocket.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                break;
            }
        }
    }

和一个带有pybluez脚本的 rfcomm客户端：

    service_matches = find_service( uuid = uuid, address = addr )

if len(service_matches) == 0:
    print("couldn't find the SampleServer service =(")
    sys.exit(0)

first_match = service_matches[0]
port = first_match["port"]
name = first_match["name"]
host = first_match["host"]

print("connecting to \"%s\" on %s" % (name, host))

# Create the client socket
sock=BluetoothSocket( RFCOMM )
sock.connect((host, port))

两个设备都已同步。 android应用程序正在运行并在socket = mmServerSocket.accept（）中等待，执行脚本时结果始终相同：

bluetooth.btcommon.BluetoothError: (104, 'Connection reset by peer')

android应用不会继续执行，而是继续在同一mmServerSocket.accept（）中等待

我用不同的UUID进行了测试，但是当前是：

private static final UUID MY_UUID = UUID.fromString("94f39d29-7d6d-437d-973b-fba39e49d4ee");
private static final String NAME = "BluetoothTest";

有人可以帮助我吗？我不知道。

谢谢。
