Remote firmware update

Update the tracker firmware without sending an engineer, without moving the vehicle to a workshop, without stopping the fleet. That is FOTA: Firmware Over-The-Air. The device only needs an active 2G/4G connection.

01 · Platform

What FOTA Web is

FOTA Web is the console Teltonika provides to manage your device firmware remotely. You schedule the update, pick which units, and the change applies on the next communication cycle. You do not touch the device.

02 · Flow

How it works

01
IMEI registration

You register the devices in your FOTA Web account.

02
Firmware version

You pick the version Teltonika has published for your model (FMC920, FMC150, etc.).

03
Scheduling

When to apply it and to which group of devices.

04
Apply

The device downloads the binary, validates the signature and reboots. No on-site intervention.

03 · Cases

Where it makes a difference

  • Security patches — vulnerability in the current firmware fixed across 200 vehicles with no scheduled visits.
  • New factory features — support for an additional CAN parameter or a new protocol.
  • Fixes — a fuel reading bug fixed in the next revision.
  • Bulk reconfiguration — server change, reporting interval or codec applied in bulk.
04 · Requirements

What you need

  • FOTA Web account (free with purchase).
  • Registered device IMEI.
  • Active 2G/4G data connection.
  • Firmware approved by Teltonika for the model.
05 · Hardware

Compatibility

The entire Teltonika family with a cellular module supports FOTA: FMC (4G), FMM, FMB (2G/3G), TAT (asset trackers) and TFT. Your device ships with it from the factory; it is not an accessory.
