Développements en cours mises à jour.

Jan 2026

  • Working on an enclosure for the T-Sim modules, using Fusion this time.
  • Working on the firmware for the T-Sim modules
    • The GPS collection and mqtt uplink to the Web server side seems to give good results.
    • The module writes the GPS locations in a file.
      • a File is created in a directory under the day’s name each time the module is started
      • a Web Filesystem management page is now implemented (using a modified EspFileManager library)

Dec 2025

  • Road test A7670 esp 32, filtering GPS readings somehow difficult using H/V/PDOP and distance, a new filter has been setup using speed and distance.

  • Finally got both modules to work properly, a Haversine routine has been implemented to compute the distance between the GPS measures.

  • Working on a T-SIM S3 A7670G

  • Web side of the tracker is now operational for multiple trackers

  • The GPS of the 7670E is less sensitive then the 7600’s unit, MQTT message being sent based on the distance between measurement has to be adapted.
