what is the reason of esp32 hang

[kishan patel]

Hello,
Actually, i am using esp32 dev-kit. I have flashed firmware of AT-command to it.
I simply connect to WiFi network by using "AT+CWJAP" command.
It connect successfully.
Now, i continuosly check of available AP near by it(Use AT+CWLAP), it make hang device after some time.
I have also tried to use "AT+RST", but its not work in this scenario and i have to do hardware-reset.
What should be reason behind this?

Thanks and Regards,
Kishan Patel.
