Idle power save
When you use the AT_IPWSAVSCHD command you set the power save mode to Idle power
save, provided you define an idle time (more that zero) and you define at least one valid wake-
up method.
To set the idle time before power save
If you are using power save mode
Idle power save
and none of the conditions that prevent
power save state are present (mentioned in the section
on page 35), the
system will go into power save state after a defined idle time. You can configure this Idle time
with the AT command _IPWSAVSCHD as follows:
1. Set the idle time before power save:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example:
AT_IPWSAVSCHD=IDLE_TRG,15
In this example, the power save mode is Idle power save, the trigger is idle time
(IDLE_TRIG), and the idle time before the terminal enters power save state is 15 minutes.
To configure wake up on daily basis
1. Set the time of day that the terminal must wake up from power save:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example:
AT_IPWSAVSCHD=TOD_TRG,24:00
In the example above, the wake-up method Time Of Day (TOD) is selected, and the time of
day to wake up from power save is 24:00 UTC time.
To configure Wake-On-LAN
1. Set the Wake-On-LAN function to On or Off:
AT_IPWSAVSCHD=<psmode>,<psvalue>
Example:
AT_IPWSAVSCHD=WOL_STATUS,1
In the example above, the wake-up method Wake-On-LAN is selected. This means the
terminal will wake up from power save when a “Magic packet” is received on the LAN
interface.
Important
If the terminal was already in Idle power save mode before the command and
the Idle time is set to “0” with the AT command below, or you have not defined
a wake-up method, the Power save function is disabled and the terminal will be
always on
.
If the terminal was
not
in Idle power save mode and the time is set to “0”, the
parameter is stored, but the power save mode is
not
changed to Idle power save
mode.
Important
Remember to configure one or more wake up functions - otherwise the
EXPLORER 323 will not be able to enter power save state.
Note
If the wake-up time of day is set to “0” with this AT command, the “Wake up time of
day” function is disabled! You must configure another wake-up method.
