I called connectToDevice and connect to android phone, then connect again, I want to test the interface，all seemed ok，but when the android phone 's macaddress changed ,i connect it with the new mac address, will block. and even if I disconnect the old connection (disconnectFromDevice), then connnect to the new address,it will block.

and when connect a wrong mac address, it will block too,no error or slot event appear, I don't konw why
