⑥. Reset or power-down restart the module and repeat step
⑦. Next, we need to enter SmartConfig mode.
a. Enter the AT command "AT+SMT=60" in the Send text box of the serial debug assistant (please add a line break, i.e.
add the Enter key after entering the command "AT+SMT=60") and click Send to send the command. (The 60 in the AT
command here means that the WiFi hotspot is not connected after 60S, and will time out of SmartConfig mode) (During
this 60S period, the module waits to accept the command sent by the phone, and lights up LED1 (GPIO9 is pulled low)
if it is accepted successfully)
If the serial port shows "Enter into Smartconfig" message and LED3 (GPIO11 pull low) is lit, it indicates that it has
entered SmartConfig mode, otherwise, please retry the above steps.
