3.2 Operating modes
The table below briefly summarizes the various operating modes referred to in the following
chapters.
Table 6: Overview of operating modes
Mode Function
Normal operation GSM/GPRS
SLEEP
The module will automatically go into SLEEP mode if DTR is
set to high level and there is no interrupt (such as GPIO
interrupt or data on serial port).
In this case, the current consumption of module will reduce to
the minimal level.
During SLEEP mode, the module can still receive paging
