3.15. Operating status indication
The STATUS pin is set as an output pin and can be used to judge whether module is power-on,
please refer to
Chapter 3.4
. In customer design, this pin can be connected to a GPIO of DTE or be
used to drive an LED in order to judge the module’s operation status. A reference circuit is shown
in figure 43.

3.16. General purpose input & output (GPIO)
The module provides a limited number of General Purpose Input/Output signal pins. The driving
capability of these pins is 4mA. Every GPIO can be configured as input or output, and set to high
or low when working as an output pin by “AT+CEQGPIO” command. Before using these GPIO
pins, customer should configure them with “AT+CEQGPIO=1,x,x,x,x” first. For details, please
refer to
