Firmware versions

FIRMWARE VERSION	RELEASE DATE	CHANGES
03.01.00.Rev.14	2025.05.27	Features Improvement: Enhanced MQTT functionality for reliable data transmission to AWS over RS232/RS485 TCP/UDP link modes. Improved MQTT command handling for sending and receiving GPRS commands via AWS servers Resolved issue with the tracker not sending beacon data to Azure IoT. Fixed an issue where the tracker failed to send beacon records exceeding 1024 bytes over UDP. Updated odometer logic for more accurate total distance tracking. CAN/Tachograph Improvements: Stability improvements for handling CAN bus message overflow. Enhanced accuracy of FMS Eco-Driving metrics: total distance and fuel usage. Improved detection of driver state change events from the tachograph during sleep mode. Fixed issues where FMS and Manual CAN functions were not operating as intended. Corrected logic for Manual CAN command timing: Commands now respect the configured timeouts. Removed extra transmissions beyond the configured count. Ensured correct data transmission even with data masks < 8 bytes. General Improvements: Fixed incorrect handling of spaces in APN usernames and passwords. Fixed an issue with FOTA Web configuration downloads being unsuccessful. Resolved issue where data link was closed after 30 seconds unexpectedly. New Implementation Added new SMS/GPRS commands for accessing FMS Eco-Driving accumulator data. Introduced support for Codec 14 GPRS commands.
