Product Usage Instructions
GPS Sleep Mode
FMB640 can enter GPS sleep mode when enabled. The device turns
off the GPS module and creates new periodic records to save power.
To enter GPS sleep mode, the following conditions must be met:
-
Device configured for GPS Sleep mode with sleep timeout
reached -
Device time synchronized with GPS satellites
Deep Sleep Mode
In deep sleep mode, the GNSS receiver is set to sleep mode, and
the GSM/GPRS module is turned off. The device saves the last known
coordinates and decreases power usage. To enter deep sleep mode,
ensure the following conditions are met:
-
Device configured in Deep Sleep mode with sleep timeout
reached -
Device time synchronized with GPS satellites
Online Deep Sleep Mode
In this mode, the device functions like deep sleep mode but
maintains connection to the GSM network, increasing power
consumption. The device can still send/receive SMS and make/accept
calls without closing the GPRS context. To enter online deep sleep
mode, meet the same conditions as for deep sleep mode.
FAQ
Q: How do I exit Online Deep Sleep mode on FMB640?
A: FMB640 exits online sleep mode if movement by accelerometer
or configured movement source is detected, or if the ignition
(configured ignition source) is turned on.

Video Demonstration
Here is a visual demonstration of the sleep modes and how they they affect the
device.
GPS Sleep mode
FMB640 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, FMB640 turns the GPS module off and continues making
new periodic records. As a result power usage decreases, in turn saving
vehicle battery. FMB640 will enter GPS sleep mode if ALL of these conditions
are met:
FMB640 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 – FMB640 time is synchronized with GNSS satellites and GPS
fix is
obtained; After Time Sync – FMB640 time is synchronized over NTP, NITZ, or
GNSS satellites; Always – FMB640 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. USB is not connected. FMB640 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, FMB640 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 FMB640 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.
FMB640 can enter deep sleep mode if ALL of these conditions are met:
FMB640 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 – FMB640 time is synchronized with GNSS satellites and GPS
fix is obtained; After Time Sync – FMB640 time is synchronized over NTP, NITZ,
or GNSS satellites;
Always – FMB640 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 FMB640 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 FMB640 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. USB is not
connected. FMB640 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. FMB640 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.
