How to register devices automatically with a universal license

A universal license lets many devices register in your Emteria account on their own. You don't need to enter a license code on every device. Each device gets a license of its own and joins the group you chose. A device that was registered before gets its previous license back.

You use a universal license together with device provisioning. The Hub creates it for you when you choose a group in your provisioning settings.

How it works

1. In your provisioning settings, you choose the group your devices should join.
2. The Hub creates a universal license for this group and adds it to the provisioning file.
3. You install Android OS built by Emteria and give the device the provisioning file on its very first start.
4. The device registers automatically and joins the group. Nobody needs to enter a code.

Set up automatic registration

1. Log in to the Emteria Hub.
2. Open Provisioning and choose your provisioning settings, or create new ones.
3. Under Device registration, choose the Group your devices should join.
4. Click Save. The Hub creates the universal license for this group. You find it on the Universal licenses page, with its target group and the provisioning settings that use it.
5. Click Export and give the file to your devices. The introduction to device provisioning explains how.

That's it. Every device that starts with this provisioning file registers automatically.

Clone SD cards for many devices

With a universal license, you can set up one SD card and copy it for all your devices. When a copied card starts in a new device, the Emteria License app notices the new hardware. It then registers the device automatically in the same group.

Register a device manually with the provisioning file

Normally, devices register on their own during the first start. If a device isn't registered after the setup, for example because it had no internet connection, you can start the registration by hand:

1. Open the app drawer and start the Emteria License app.
2. Tap Continue with OEM config data. You only see this option if the device has a valid provisioning file.
3. The device registers with the universal license from the file and joins its group.
4. Restart the device to finish the registration.

Keep your universal license secret

If a code gets out:

1. Open Universal licenses and delete the code. It's also removed from every provisioning that contains it. Devices can no longer register with the old provisioning file.
2. Open your provisioning settings, choose the group under Device registration again and click Save. This creates a new universal license.
3. Export the provisioning file again and use the new file from now on.

FAQ

Do I need a paid plan?

No. Device provisioning and universal licenses are available on every plan, including the free plan.

Which universal licenses do I have?

The Universal licenses page lists all of them. For each code, you see its target group and the provisioning settings that use it.

Do I need free licenses in the group?

No. If the group has no free license left, a new one is created automatically when a device registers.

What happens to registered devices if I delete a universal license?

Nothing. Devices that are already registered keep their licenses. New devices can no longer register with it, and the Hub removes it from your provisioning settings.

I deleted a universal license by mistake. How do I restore it?

Devices that use a provisioning file with the deleted code can't register anymore. To make the code work again:

1. Find the license code in your exported provisioning file (open it with a text editor).
2. Open Universal licenses, enter the code and click Add.
3. Choose the Target group, the group your devices should join.

If you haven't given the file to any devices yet, it's easier to create a new universal license: choose the group under Device registration again, save and export a new file.
