FT Device Firmware Update Information

Introduction

The Device Firmware Update (DFU) feature enables FT platform devices to update their firmware either:

  • Over-the-air (OTA) via FOTAWEB
  • Locally through a USB connection using TCT (Teltonika Configuration Tool)

This ensures devices always run the latest, most stable, and secure firmware versions.

Firmware image types

There are three main firmware image types used in the FT platform:

  • FTx.Ver.x.x.x-rc.x.e.xim / FTx.Ver.x.x.x.x.e.xim
 Example: FTx.Ver.0.5.0-rc.9.e.xim
  • FTx.Ver.x.x.x-rc.x.wmi.e.xim / FTx.Ver.x.x.x.wmi.e.xim
 Example: FTx.Ver.1.5.0-rc.9.wmi.e.xim
  • FTx.Ver.x.x.x-rc.x.tpack / FTx.Ver.x.x.x.tpack
 Example: FTx.Ver.3.0.3.tpack

Versioning Scheme

  • FTx.Ver.x.x.x-rc (e.g. 2.1.0-rc.7) – Release Candidate: evaluation version, still in the stabilization phase.
  • FTx.Ver.x.x.x (e.g. 2.1.4) – Stable Release: factory-used and publicly available for OTA updates.

Image Details

  • .e.xim – Initial, deprecated DFU image type (used for firmware older than 1.1.0-rc.1).
  • .wmi.e.xim – Introduced from 1.1.0-rc.1. Contains additional metadata (image type, version, hardware support, etc.). Protects devices from being upgraded to unsupported versions.
  • .tpack – Support introduced from 2.0.0-rc.1. Includes additional packages for CAN, BLE, and MCU firmware updates.

Image File Distribution Policy

  • Stable firmware image types such as 1.5.1, 2.1.1, and 2.1.4 are currently distributed only via the FOTAWEB platform
  • Due to the introduction of a new image type, stable firmware version 3.0.3 is not distributed directly to client FOTAWEB accounts. Firmware updates to version 3.0.3 will be performed by our Support team. To have devices in your fleet updated, please contact your Sales Manager or submit a request directly through the HelpDesk system.
  • Once a stable release is available, you can perform updates over-the-air (OTA).
  • If OTA update is not viable option (e.g., restricted connectivity), please contact your Sales Manager or Support via HelpDesk System for further assistance.

Update Routes

Updating devices sometimes requires intermediate steps.

  • From 0.40.3 → 1.5.1 → must use .e.xim image type.
  • From 1.5.1 → 2.1.4 → must use .wmi.e.xim image type.
  • From 2.1.4 → 3.0.3 → must use .tpack image type.

Examples

  • Upgrading from 0.40.3 to 2.1.4:
  1. Update first to 1.5.1 (enables usage of .wmi.e.xim image type).
  2. Then update to 2.1.4 using .wmi.e.xim.
  • Upgrading from 0.40.3 to 3.0.3:
  1. Update first to 1.5.1.
  2. Then update to 2.1.4. (enables usage of .tpack image type).
  3. Finally, update to 3.0.3 using .tpack.

Downgrade Policy

  • Downgrades from 1.x.x → 0.x.x are not allowed
  • Downgrades from 2.x.x → 1.x.x or 0.x.x are not allowed
  • Downgrades from 3.x.x → 2.x.x or 1.x.x or 0.x.x are not allowed

Hardware Support

Some hardware versions are deprecated and not supported by newer firmware.

Please always verify device compatibility in the Firmware Versions Table.

If unsure, contact your Sales Manager or Support via HelpDesk System.
