3.15. STATUS

The STATUS pin is an open drain output signal for indicating the module's operation status. It can be
connected to a GPIO of DTE with a pulled-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.

NOTE
It is prohibited to supply any voltage to STATUS pin when VBAT is removed.

3.16. SLEEP_IND*

The SLEEP_IND pin is used for indicating the module's sleep status. When the module is entered into
sleep mode, the SLEEP_IND will present a high level.
