FMB640 Sleep modes: Difference between revisions

While in deep sleep mode, {{{model|FMB640}}} sets GNSS receiver to sleep mode and turns off GSM/GPRS module (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. 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 {{{model|FMB640}}} will enter deep sleep mode immediately.<br/>Because a lot of functions are disabled in deep sleep mode 13 I/O elements are disabled from records that are generated in this mode: GSM Signal, GNSS Status, GNSS PDOP, GNSS HDOP, Speed, GSM CellID, GSM Area Code, Fuel rate GPS, Active GSM Operator, Trip Odometer, Total Odometer, Fuel Used GPS and ICCID.
