3.21. STATUS
The STATUS pin is an output for module’s operation status indication. When the module is turned on
normally, the STATUS outputs high level.

DO
Indicate the module's operation status
1.8 V power domain.
If unused, keep it open.
The STATUS cannot be used as the indication of power-down state when VBAT doesn’t supply power to
the module.
