Sudden Momentary Power Loss Timer $WPLTIME
Description: This command sets the length of the sudden momentary power loss (SMPL) timer.
The Sudden Momentary Power Loss feature requires that a timer be set to indicate how long after
main battery loss SMPL should stay active. If power from the main battery returns to its valid
range before the timer expires then the power management circuits initiate a power on sequence
without software intervention.
The timer is set after the command to enable SMPL (AT$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).
