3.16. STATUS
The STATUS pin is an open drain output for module’s operation status indication. It can be connected to a
GPIO of DTE with a pulled-up resistor, or as an 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 23: Pin Definition of STATUS
Pin Name Pin No. I/O Description Comment
STATUS 61 OD Indicate the module’s operation status
An external pull-up resistor
is required.
If unused, keep it open.
The following figure shows different circuit designs of STATUS, and you can choose either one according
to the application demands.
