3.19. STATUS
The STATUS pin is an open drain output for indicating the module’s operation status. It can be connected
to a GPIO of DTE with a pull up resistor, or as an LED indication circuit as shown below. When the module
is turned on normally, the STATUS pin will present a low level state. Otherwise, it will present
high-impedance state.
