Product Usage Instructions
GPS Sleep mode
TFT100 is capable of entering GPS sleep mode to conserve power.
The device will turn off the GPS module and continue recording
periodically. To enter GPS sleep mode, the following conditions
must be met:
-
TFT100 is configured for GPS Sleep mode and the sleep timeout
is reached. -
Device time is synchronized with GPS satellites.
-
Movement is not detected by the accelerometer.
-
Ignition is off.
-
No SMS messages are being received.
The device will exit GPS sleep mode if movement is detected or
ignition is turned on.
Deep Sleep mode
In deep sleep mode, TFT100 puts the GNSS receiver to sleep and
turns off the GSM/GPRS module. The device cannot be woken up via
SMS in this mode. To enter deep sleep mode, the following
conditions must be met:
-
TFT100 is configured for Deep Sleep mode and the sleep timeout
is reached. -
Device time is synchronized with GPS satellites.
The device will exit deep sleep mode if movement is detected or
ignition is turned on.
FAQ
Q: Can TFT100 be woken up via SMS in Deep Sleep mode?
A: No, in Deep Sleep mode, the GSM/GPRS module is turned off, so
the device cannot be woken up via SMS.
Q: What happens if movement is detected while in GPS Sleep
mode?
A: If movement is detected, the device will exit GPS Sleep
mode.
Q: How does TFT100 save power in Ultra Deep-sleep mode?
A: In Ultra Deep-sleep mode, the device minimizes power
consumption by shutting down all non-essential functions.

There are four sleep modes: GPS sleep, Deep sleep, Online Deep sleep, and
Ultra Deep-sleep mode.

Video Demonstration
Here is a visual demonstration of the sleep modes and how they they affect the
device.
GPS Sleep mode
TFT100 is able to go into GPS sleep mode if such mode is enabled. Sleep mode
timeout starts counting when the device is in STOP mode. After timeout is
reached and all conditions for GPS sleep mode are met, the device goes into
sleep mode.
When in GPS sleep mode, TFT100 turns the GPS module off and continues making
new periodic records. As a result power usage decreases, in turn saving
vehicle battery. TFT100 will enter GPS sleep mode if ALL of these conditions
are met:
TFT100 is configured to work in GPS Sleep mode and sleep timeout is reached;
Device time must be synchronized with GPS satellites. From Firmware 03.18.15
version, this condition depends on the “Records saving/sending without TS”
parameter:
After Position Fix – TFT100 time is synchronized with GNSS satellites and GPS
fix is obtained; After Time Sync – TFT100 time is synchronized over NTP, NITZ,
or GNSS satellites; Always – TFT100 will enter sleep mode without time
synchronization and GPS fix.
Movement is not detected by the accelerometer and configured movement source;
Ignition (configured ignition source) is off; There are no SMS messages being
received. On Firmware version older than 03.18.15, the device time has to be
synchronized with GNSS satellites and GPS fix has to be obtained in order for
the device to enter GPS Sleep mode.
TFT100 exits GPS sleep mode if ONE of following conditions is true: Movement
by accelerometer or configured movement source is detected; Ignition
(configured ignition source) is turned on.
Deep Sleep mode
While in deep sleep mode, TFT100 sets the GNSS receiver to sleep mode and
turns off GSM/GPRS module (hence it is not possible to wake up the device via
SMS). Despite records with the last known coordinate being saved and sent to
the AVL server (GSM/GPRS module is turned on to send data and then it is
turned off), power usage is decreased to save the vehicle’s battery.
Please note that power saving depends on two configurable parameters: Send
Period and Minimum Record Saving Period in “X on Stop Mode”. When records are
sent successfully in deep sleep mode, open link timeout counter will be
skipped and TFT100 will enter deep sleep mode immediately. Because a lot of
functions are disabled in deep sleep mode following I/O elements are disabled
from records that are generated in this mode: GSM Signal, GNSS Status, GNSS
PDOP, GNSS HDOP, GSM CellID, GSM Area Code, Active GSM Operator, Trip
Odometer, Total Odometer, Speed, Fuel Rate GPS, Fuel Used GPS and ICCID.
TFT100 can enter deep sleep mode if ALL of these conditions are met: TFT100 is
configured in Deep Sleep mode and sleep timeout is reached; Device time must
be synchronized with GPS satellites. From Firmware 03.18.15 version, this
condition depends on the “Records saving/sending without TS” parameter:
After Position Fix – TFT100 time is synchronized with GNSS satellites and GPS
fix is
obtained; After Time Sync – TFT100 time is synchronized over NTP, NITZ, or
GNSS satellites; Always – TFT100 will enter sleep mode without time
synchronization and GPS fix.
Ignition (configured ignition source) is off; Movement is not detected by the
accelerometer or configured movement source; Min. Record Saving Period (Data
Acquisition Mode settings) must be larger than Open Link Timeout parameter, so
that TFT100 could close GPRS link; The difference between Send Period (Data
Acquisition Mode settings) and Open Link Timeout must be more than 90 seconds,
so that TFT100 could close GPRS link within at least 90 seconds; There are no
SMS messages being received; Data socket(s) are closed; Data sending is not in
progress; FOTA is not in progress. On Firmware version older than 03.18.15,
the device time has to be synchronized with GNSS satellites and GPS fix has to
be obtained in order for the device to enter Deep Sleep mode.
TFT100 exits deep sleep mode if ONE of following conditions is true: Movement
by accelerometer or configured movement source is detected; Ignition
(configured ignition source) is turned on.
Online Deep Sleep mode
In this mode, the device works as in deep sleep mode, but without
deregistering from the GSM network. GSM part stays powered so this increases
power consumption. In this mode, the device should send/receive SMS and
make/accept calls. It does not close the GPRS context if one was previously
opened.
Conditions to enter online deep sleep mode are the same as entering deep sleep
mode. TFT100 exits online sleep mode if ONE of following conditions is true:
Movement by accelerometer or configured movement source is detected; Ignition
(configured ignition source) is turned on.
Ultra Deep Sleep mode
Conditions to enter ultra deep sleep mode, where GPS and GSM modem are turned
off and device functions are suspended for maximum battery saving, are the
same as entering deep sleep mode. TFT100 exits ultra deep sleep mode only when
DIN1 or movement are detected by accelerometer. Movement source and Ignition
source configuration is not taken into account in this case.
