(2*) The power supply consumption may vary by 5% depending on the temperature range
(-20 °C to +55 °C).
7.2.2.4 Indication of presence/absence of the external power supply
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of
ERCOGENER); in this case, the command
AT+GPIOGET=27
allows to know the status of the external
power supply for the internal battery.
AT+GPIOGET=27
