OTA Connect User Guide

OTA update workflow

To deploy OTA updates in production, we use the concept of a campaign. We’ll go into more details about campaigns later, but to understand the workflow, you first need to understand what goes into a campaign.

A campaign consists of the following elements:

  • The relevant software update and the supported hardware.

  • The new software versions to which you want to update.

  • The groups of devices that you want to target for this update.

In the OTA workflow, you set up each of these elements in a specific order.

Connect your devices to the OTA Connect server. The server stores the following information about each device:

  • The device name or identifier (often a VIN)

  • The serial number and control unit type of each control unit in the device

  • The software version that each control unit is currently running
