AT_CSQ doesn,t respond after AT+QIOPEN

Hi,
I am using MC60CA.
I need to update signal strength along with other data to server.
AT+CSQ returns +CSQ: 19,0 before opening TCP Connection through AT+QIOPEN.

But after TCP connection is established, AT+CSQ does not respond anything.

AT+QIMODE=0.

Is it like AT+CSQ will not work after AT+QIOPEN?

Dear Suman,
Thanks for your inquiry in Quectel forum.
Could you help to provide your test AT log to us, then we can help to confirm your issue. Normally, you should waiting for receive the response of the command AT+QIOPEN, then send AT+CSQ. Thanks!

For your issue, please check the serial port connection, and change another module to have a try, or change another connection cable, or you can check it with Quectel EVB board. Thanks!
