Power saving
The power saving configuration is disabled by default, but it can be enabled using the +UPSV AT
command. When power saving is enabled, the module automatically enters the low power idle mode
whenever possible, reducing current consumption.
During low power idle mode, the module is not ready to communicate with an external device by means
of the application interfaces, since it is configured to reduce power consumption. It can be woken up
from idle mode to active mode by the connected application processor or by network activities, as
described in
During idle mode, the module processor core runs with the RTC 32 kHz reference clock, which is
generated by an internal oscillator.
