Answer 1

Hello.

There are additional conditions for device to enter Ultra deep sleep mode, they are the same as deep sleep mode.

• FMB920 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 “Records saving/sending without TS” parameter:

• After Position Fix - FMB920 time is synchronized with GNSS satellites and GPS fix is obtained;
• After Time Sync - FMB920 time is synchronized over NTP, NITZ or GNSS satellites;
• Always - FMB920 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 FMB920 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 FMB920 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.

Make sure all these conditions are met.

If you have more questions please ask.
