  • NEW Added Faulty Device Mounting functionality
  • NEW Added GNSS Fuel counter functionality
  • NEW Added "Faulty Device Mounting" I/O element
  • NEW Added "Fuel used GNSS" I/O element

FIXES/IMPROVEMENTS

  • Refined Dead Reckoning behavior by fixing calibration inconsistencies, incorrect DR state changes during driving, and improper handling after sleep cycles. Reduced track jumps (e.g., underground parking), eliminated false movement after stop, and improved consistency between devices under identical conditions.
  • An empty mask is now used by default and functions as a pass-through, allowing unfiltered CAN data to be returned
  • Resolved an issue where devices could fail to send records in Deep Sleep mode due to premature GPRS task initialization
  • Changed default CAN baudrate setting to "Auto"
  • Resolved issues with DOUT control behavior when switching between different Output Control configurations for the immobilizer
  • Improved validation logic for domain names and IPv4/IPv6 addresses
  • Resolved an issue where PDP activation attempts were triggered despite no valid operator being selected
  • APN cycling is now performed even when the device is not registered to the network. Previously, APN switching was only triggered after successful operator registration, which could prevent connection to certain operators if an incorrect APN was used.
  • Corrected MCAN service initialization failure caused by commands configured with Send type = “Response” without assigned Manual CAN IO. Such misconfigurations previously caused the entire MCAN service to stop, making all commands unreachable.
  • Resolved an issue where the MAC address was inverted when configured via command
  • Resolved an issue where GPS log output format could change intermittently
  • Changed CAN Bitmask type to string and length to 64 bytes
  • Resolved an issue where DOUT1 could remain stuck if authorization occurred before ignition was turned on
  • Resolved an issue where the M2M SIM home network was identified as “unknown” in operator selection logic, causing it to be treated as a non-home network. This could lead to unintended behavior such as applying ban lists or prioritizing roaming operators over the actual home network.
  • Resolved an issue where operators could remain stuck on weak signal conditions without being properly banned. This has been corrected, and such failures now contribute to the PDP failure count, allowing the operator to be banned after the configured limit is reached
  • Resolved an issue where I/O elements for features with Eventual Records set to “Disabled” were not included in records while their state remained unchanged
  • Resolved an issue where modem status LED could incorrectly indicate active modem operation after external voltage or battery was disconnected. Modem status LED now correctly reflects modem state after power loss.
  • Resolved an issue where, after performing a configuration change, the device continued sending records to the previously configured server
  • Resolved an issue where lower priority scenarios did not take over DOUT control after a higher priority scenario ended
  • Resolved an issue where Auto Geofence “On Entrance” records were not generated while the device was powered by an external power source
  • Resolved an issue where DIN could trigger wake-up from Deep Sleep even when not configured as an Ignition or Movement source
  • Resolved an issue where eventual I/O records were generated even when Events were not configured in the I/O section. BLE Sensors configured for Temperature/Humidity monitoring could trigger unintended eventual records (e.g., on visibility changes), ignoring the “monitoring” operand.
  • Resolved an issue where duplicate Immobilizer Eventual records could be generated when authorization occurred before ignition transition (0 → 1)
  • Resolved an issue where scheduled records set to a 1-minute interval where not saved
  • Resolved an issue where DOUT control remained active after disabling Manual Geofence or performing a device configuration reset. DOUT now correctly stops being controlled when the feature is disabled or configuration is reset
  • Corrected connection handling after Online Sleep wake-up, where multiple small data packets triggered repeated connect–send–disconnect cycles instead of being transmitted in a single continuous session
  • Resolved an issue where a modem reset after FPLMN write cleared the FPLMN list, causing the device to repeatedly reconnect to the same banned operator, preventing stable data connection.
  • I/O elements accelerometer axis data is now displayed with ground vector being included
3.0.10 2026-03-02

HARDWARE SUPPORT
