[BSS10a] - 2024-02-28

Changed

• Changed the LED blinking behavior for temperature warning from 5s to 10s to reduce power consumption.

Fixed

• Incorrect triggering of temperature warning at temperatures below 0 degrees Celsius.

[BSS100] - 2023-09-29

Changed

• Self-Training Algorithm:
  • Introducing the new TraX self-training algorithm that adapts to the current wheelend, regardless of axle or vehicle type.
  • Adds support for driven axles.
  • Improves confidence level of wheel end failure detection by up to 95%.
• BLE Advertising interval has been increased by 100% to prevent possible sensor data packet loss.

Added

• Added ability to reset the sensor by a magnet to simplify sensor management for fleet operators, providing more flexibility and convenience.
• Added temperature warning module. An alarm is activated if the temperature surpasses a high threshold for a specified duration. Temperature alarm is visualized via LED and added to the BLE advertising payload.
• Added new data to the sensor frame format. See TraX - WEM200 - Technical Specification Connected for details:
  • Temperature alarm status.
  • Vibration monitoring statuses:
    • (0) Vibration monitoring active
    • (1) Learning phase complete
    • (2) Learning phase ongoing
    • (3) Inconsistent data
  • Firmware version.
