Query Scan Sleep State +WSPS
Description:
Syntax:
This specific command queries the state of the service scan. It returns the same data as the
+WSPS unsolicited message.
Command syntax: AT+WSPS: <state>
Command

Not in power-saving state
In power-saving state
Close Service Status Unsolicited Response +WSPS
Description:
Syntax:
This unsolicited response indicates the a change in the power save status as it pertaining to
scanning for service
Response Syntax: +WSPS: <state>
Possible Responses
+WSPS: 0

Entering power-saving state
Sudden Momentary Power Loss Timer $WPLTIME
Description:
Syntax:
This command sets the length of the sudden momentary power loss (SMPL) timer.
The Sudden Momentary Power Loss feature requires that a timer be set to indicate how long after
main battery loss SMPL should stay active. If power from the main battery returns to its valid
range before the timer expires then the power management circuits initiate a power on sequence
without software intervention.
The timer is set after the command to enable SMPL (AT$WSMPL=1) has been issued, it is not
set after issuing the $WPLTIME command. Once SMPL has been enabled the timer cannot be
changed until SMPL is disabled.
The setting is persistent. As a result, it is saved after a power cycle. The default is 3 (2.0
seconds).
Command Syntax: AT$WPLTIME=<State>
