Template:FMA Sleep modes: Difference between revisions

There are two sleep modes:sleep and Deep sleep.

Sleep mode

FMB1YX is able to go to sleep mode after configurable Sleep timeout.
Sleep mode timeout starts counting when device is in STOP mode. After timeout is reached and all conditions for sleep mode are met, the device goes into sleep mode. When in sleep mode, FMB1YX turns GPS module off and stops making new periodic records. As a result power usage decreases, in turn saving vehicle battery.
FMB1YX will enter sleep mode if ALL of these conditions are met:

FMB1YX is configured to work in Sleep mode and sleep timeout is reached;
Device time is synchronized with GNSS satellites and GPS fix is obtained;
Movement is not detected by the accelerometer or configured movement source;
Ignition (configured ignition source) is off;

FMB1YX 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.
USB cable is connected.

Deep Sleep mode

While in deep sleep mode, FMB1YX sets the GNSS receiver to sleep mode and turns off GSM/GPRS module (hence it is not possible to wake up device via SMS). Despite records with last known coordinate being saved and sent to AVL server (GSM/GPRS module is turned on to send data and then it is turned off), power usage is decreased to save 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 FMB1YX 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. FMB1YX can enter deep sleep mode if ALL of these conditions are met:

FMB1YX is configured in Deep Sleep mode and sleep timeout is reached;
Device time is synchronized with GNSS satellites and GPS fix is obtained;
Ignition (configured ignition source) is off;
Movement is not detected by the accelerometer or configured movement source;
Min. Record Saving Period (FMB1YX Data acquisition mode settings) must be larger than Open Link Timeout parameter, so that FMB1YX could close GPRS link;
The difference between Send Period (FMB1YX Data Acquisition Mode settings) and Open Link Timeout must be more than 90 seconds, so that FMB1YX could close GPRS link within at least 90 seconds;
Data socket(s) are closed;
Data sending is not in progress;
FOTA is not in progress.

FMB1YX 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.

	Note: In order to save GPRS traffic records saved in deep sleep mode do not contain below listed I/O elements information: PDOP, HDOP, Odometer, Speedometer, iButton ID, Cell ID, Area Code, Temperature and GPS power
