尝试连接时，我收到蓝牙连接失败错误。

    BluetoothSocket.cpp(8398): initSocketNative
    BluetoothSocket.cpp(8398): ...fd 53 created (RFCOMM, lm = 0)
    BluetoothSocket.cpp(8398): initSocketFromFdNative

    BluetoothSocket.cpp(8398): destroyNative
    BluetoothSocket.cpp(8398): ...asocket_destroy(53) complete

让我知道我在哪里做错了。

我的代码段：

    mmSocket = device.createInsecureRfcommSocketToServiceRecord(MY_UUID);
    mmSocket.connect();
