Power saving
SLEEP mode reduces the functionality of the modules of the BOLERO40 series devices to a
minimum and, thus, minimizes the current consumption to the lowest level. The BOLERO40
can be set into the sleep mode using the command
$PFAL,Sys.Device.ChargeSleep
or with one or more parameters listed in the
table below. Following SLEEP modes are supported by the BOLERO40 series devices:
Modes
Description
IGN
Device wakes-up when a rising edge (Low to High signal) on the IGN pin is detected.
Wakeup=15:30:00
Device wakes up at the set wake up time.
Timer=1:20:00
Device wakes up when timeout has expired.
Motion
=200
Device wakes up when the set motion value is exceeded.
ExtPwrDetect
Device wakes up when external power connection is detected.
ExtPwrDrop
Device wakes up when external power disconnection is detected. For battery powered
devices, the device wakes up when the battery voltage drops below the minimum.
LowBat=3.7
Device wakes up when the battery voltage drops below the specified value
Example
$PFAL,Sys.Device.ChargeSleep=
IGN+Motion=200
IMPORTANT
:
The sleep and wake-up procedures are quite different depending on the selected
ChargeSleep mode.
When activating any sleep mode, make sure that the internal battery has enough power to
safely wake up the device from that sleep mode. If the internal battery does not have enough
power, the device can’t complete the wake up process
.
