11. AT+WAKEUPGPIO – set a GPIO to wake ESP8266 up from light-sleep mode
This command sets a GPIO to wake the ESP8266 up from light-sleep mode. Please note that the
<trigger_GPIO> and the <awake_GPIO> in the command cannot use the same GPIO.
After being waken up by <trigger_GPIO>, when the ESP8266 attempts to sleep again, it will check the
status of the <trigger_GPIO>:
• if it is still in the wakeup status, the EP8266 will enter modem-sleep mode instead.
if it is NOT in the wakeup status, the ESP8266 will enter light-sleep mode.

AT+WAKEUPGPIO – set a GPIO to wake ESP8266 up from light-sleep mode
ESP8266 will be wakened from light-sleep, when the GPIO0 is in low-level.
AT+WAKEUPGPIO=1,0,0
ESP8266 will be wakened from light-sleep, when the GPIO0 is in high-level.
And after waking up, the GPIO13 will be set to high-level.
Example
AT+WAKEUPGPIO=1,0,1,13,1
Disable the function that ESP8266 can be woken up from light-sleep by GPIO.
AT+WAKEUPGPIO=0
AT+WAKEUPGPIO=<enable>,<trigger_GPIO>,<trigger_level>,
Command
[<awake_GPIO>,<awake_level>]
Response OK
<enable>
<trigger_GPIO>
<trigger_level>
Parameters
[<awake_GPIO>], optional
[<awake_level>], optional
