3.1.1.3 Fast Standby Mode
In this mode, SIM device and GSM/GPRS features like GSM voice or data call, SMS,
GPRS data transfer are not available. The embedded application is running and the
serial port remains active (AT commands are available). If any data has to be
transmitted over the network, this mode has to be turned off.
To switch the Wireless CPU
®
to this mode use "AT+WBHV=1,1" command. The
Wireless CPU
®
must be restarted in order to take the new behavior into account.
To disable this mode, use the "AT+WBHV=1,0" command and restart the Wireless
CPU
®
.
3.1.1.4 Slow Standby Mode
This mode is a low power consumption mode. It combines Fast standby mode and
Slow idle mode in terms of feature availability.
In this mode, SIM device and GSM/GPRS features like GSM voice or data call, SMS,
GPRS data transfer are not available. In addition, the Wireless CPU
®
has restricted

®
power processing.
The Wireless CPU
®
automatically switches back to idle state after all Open AT
®
treatments.
To switch the Wireless CPU
®
to this mode, use "AT+WBHV=1,2" command. The
Wireless CPU
®
must be restarted in order to take the new behavior into account.
To disable this mode, use "AT+WBHV=1,0" command and restart.
