Template:ATX System

Power Saving settings

Puts the device into a power-saving mode, preserving the power consumption from the external source or the internal battery. The device enters this mode after the conditions are met.

Online sleep

• In Online Sleep mode, the device manages the connection only when records need to be sent. The connection is opened at periodic intervals to send records and closed immediately after, without any timeout.
• Changing the Permanent Link setting during Online Sleep will wake up the device to apply the new configuration.
• With Permanent Link enabled, the device maintains a constant connection, sending records immediately as they are generated, rather than waiting for the next scheduled send. After sending connection remains open.

Disabled modules in Online sleep

When device goes into sleep mode, some modules are turned off to consume less power. Listed below are the modules and scenarios that are turned off in common with all modes and those that are disabled specifically for the Online sleep mode:

• GNSS
• Scenarios (Common):
  • SNTP time synchronization

Online sleep entry conditions

All entry conditions must be met:

• Movement is not detected by the configured movement source.
• Device time must be synchronized. This condition depends on the “Record Settings -> Saving / sending mode parameter.
  • After Position Fix - device time is synchronized with GNSS satellites and GPS fix is obtained.
  • After Time Sync - device time is synchronized over NTP, NITZ, or GNSS satellites.
  • Always - device will enter sleep mode without time synchronization and GPS fix.
• Sleep timeout is reached.
• There are no SMS messages being received.
• Data sockets are closed (ignored when permanent link is enabled)
• FOTA WEB connection is not in progress.

Online sleep exit conditions

At least one exit condition must be met:

• Movement is detected.
• Periodic wake-up (if enabled).

Power off sleep

Disabled modules in Power off sleep

When device goes into sleep mode, some modules are turned off to consume less power. Listed below are the modules and scenarios that are turned off in common with all modes and those that are disabled specifically for the Power off sleep mode:

• Modem
• GNSS
• IMU (Inertial Measurement Unit)*
• FOTA WEB
• Charger service*

*^{If power bank mode is selected and charger is enabled, device will not enter in Real Time clock sleep and stay in Power off sleep mode, which results in a similar mode to Deep Sleep.}

• Scenarios (Common):
  • LEDs (Navigation and Status)
  • SNTP time synchronization

Power off entry conditions

All entry conditions must be met:

• Movement is not detected by the configured movement source.
• Device time must be synchronized. This condition depends on the “Record Settings -> Saving / sending mode parameter.
  • After Position Fix - device time is synchronized with GNSS satellites and GPS fix is obtained.
  • After Time Sync - device time is synchronized over NTP, NITZ, or GNSS satellites.
  • Always - device will enter sleep mode without time synchronization and GPS fix.
• Sleep timeout is reached.
• There are no SMS messages being received.
• Data sockets are closed (ignored when permanent link is enabled)
• FOTA WEB connection is not in progress.
• TCT is not connected.
• USB is not connected. This condition does not apply if Power bank mode is enabled.

Note: Starting with 3.7.0 Firmware, USB presence check will be replaced with TCT connection check.

Power off sleep exit conditions

At least one exit condition must be met:

• Movement is detected.
• USB is disconnected.
• Button is pressed.
