Q24 plus modules serial port response block


hi ,everyone!
I use" AT+WIPCREATE, AT+WIPDATA “command in my program to connect my server successfully filrst time, and i use the response:”+WIPREADY: 2,1",“CONNECT” as a flag of the connection.
but when i close the connection ,and try to connect my server next time ,the serial port supposed to give me responses :"+WIPREADY: 2,1",“CONNECT” immediately,but it seems like the serial port is blocked,it never give me responses until i quit my program. and when i execute my program again immediately ,the response will be shown.
can i get ur help ? TKS!


Is that an Open-AT application, or a program on some external microcontroller, PC, or whatever?
