3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to in the following
chapters.
Table 6: Overview of operating modes
Normal
operation
GSM/GPRS
SLEEP
Various power save modes set with AT+CFUN
command.
Software is active to minimum extent. If the module
was registered to the GSM network in IDLE mode, it is
registered and paging with the BTS in SLEEP mo-
de, too. Power saving can be chosen at different le-
vels: The NON-CYCLIC SLEEP mode
(AT+CFUN=0) disables the AT interface.
The CYCLIC SLEEP modes AT+CFUN=7 and 9 al-
ternatingly activate and deactivate the AT interfaces
to allow permanent access to all AT commands.
GSM IDLE Software is active. Once registered to the GSM net-
work, paging with BTS is carried out. The module is
ready to send and receive.
GSM TALK Connection between two subscribers is in progress.
Power consumption depends on network coverage
individual settings,such as DTX off/on,FR/EFR/HR,
hopping sequences, antenna.
GPRS IDLE Module is ready for GPRS data transfer, but no data
is currently sent or received. Power consumption de-
pends on network settings and GPRS configuration
(e.g. multislot settings).
GPRS DATA GPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control le-
vel), uplink/downlink data rates, GPRS configuration
(e.g. used multislot settings) and reduction of max-
imum output power.
Power Down Normal shutdown after sending the AT^SMSO command.
Only a voltage regulator is active for powering the RTC. Software is not
active. Interfaces are not accessible.
Operating voltage (connected to BATT+) remains applied.
See the following sections for the various options of waking up BGS12 and proceeding from
one mode to another.
