Introduction: Apply a firmware update to devices

To apply a firmware update to devices, you must create a campaign and specify which firmware version will be pushed. You then assign devices to that campaign. When you activate the campaign, the firmware update is pushed to the assigned devices. Every 24 hours from the time the campaign is activated, the Knox E-FOTA client app on the assigned devices automatically polls the Knox E-FOTA server to check for any policy changes made to the campaign.

Knox E-FOTA allows you to create two types of campaigns:

• Normal campaign—Allows you to assign production firmware to devices
• Test campaign—Allows you to assign dummy firmware to devices

This section describes how to create the different types of campaigns.
