Status; Behaviors Of Ri - Quectel EC25-AUX Hardware Design

3.18. 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 LED indication circuit as below. When the module is turned
on normally, the STATUS will present the low state. Otherwise, the STATUS will present high-impedance
state.
Table 22: Pin Definition of STATUS
Pin Name Pin No.
STATUS 61
The following figure shows different circuit designs of STATUS, and customers can choose either one
according to customers' application demands.
NOTES
The status pin cannot be used as indication of module shutdown status when VBAT power supply is
removed.

3.19. Behaviors of RI

AT+QCFG="risignaltype","physical" command can be used to configure RI behavior.
No matter on which port a URC is presented, the URC will trigger the behaviors of RI pin.
