AIR 602 not responding suddenly

Hi,



I connected the module to my MCU and started coding my MCU.



At power on, the module gave a message - \r\nready\r\n



I wrote commands for the following



AT+E

AT+wprt=!0

AT+SSID=!

AT+KEY=!1,0,

AT+NIP=1…

AT+ATM=!0

AT+ATRM=…



Each one of them returned response as per AT command manual.



Suddenly, the module stopped responding.

No response messages. If we restart power, we don’t get " \r\nready\r\n" message also.



Can someone urgently suggest solution.

Regards

Hi,
