A license covers one pair of glasses for one app: the serial number of the glasses paired with the Android application ID or iOS bundle ID of your app. Everything on this page happens on the Enterprise page of the developer portal.

How licenses work

• Each serial number and app ID pair uses one license.
• Licenses do not expire.
• Adding another app to glasses you already added uses another license.
• Licenses cannot be returned and devices cannot be removed.

The top of the Enterprise page shows how many licenses you have used out of your total.

Agree to the terms

Before you add devices or download licenses, agree to the Enterprise SDK License Terms. The agreement panel stays on the Enterprise page until you agree.

Add device and Import CSV appear once you have agreed to the terms and have licenses left.

Add a device

1. Select Add device.
2. Enter the Serial number. It is printed on the glasses box and looks like S000XXXX000000.
3. Enter the App ID: the Android application ID or iOS bundle ID of the app that will connect to these glasses, for example com.example.app. App IDs already on your account are offered as one-click picks.
4. Select Next.
5. Check the serial number against the label on the glasses box, type it again, then select Use 1 license and add.

If the glasses already have a license for that app ID, the portal says so and uses no license.

Import devices from CSV

To add many glasses for one app at once, import a CSV file:

• UTF-8, with a single column.
• Row 1 is the header sn, then one serial number per row.
• Up to 500 rows per file.
• Every device in the file gets the app ID you enter.

sn
S000ABCD000001
S000ABCD000002

1. Select Import CSV.
2. Enter the App ID, then select Choose file and pick your CSV.
3. Select Continue. The preview counts the new devices, the devices that already have this app ID, duplicate rows and rows that are not a serial number, and lists the rejected rows.
4. Check each new serial number against its glasses box, type the number of licenses the import uses, then select Use N licenses and add.

Only new devices use a license. If the file needs more licenses than you have left, the preview tells you how many you are short. Remove that many new rows, or contact sales for more licenses.

Download licenses

1. Select Download licenses.
2. Pick the app.
3. Select Download.

You get one file, <app ID>.licenses.json, with a license for every device added for that app:

{
  "format": "enterprise-sdk-license-v1",
  "app_id": "com.example.app",
  "licenses": [
    { "sn": "S000ABCD000001", "signature": "<signature>" },
    { "sn": "S000ABCD000002", "signature": "<signature>" }
  ]
}

Ship the file inside your app or deliver it from your own backend. The file covers the devices on the app when you download it, so download it again after you add devices. To load the file in your app, see Install the SDK.

More licenses

When all your licenses are in use, Contact sales replaces Add device and Import CSV. Selecting it opens your mail app with a message to our team, with your account and license count filled in.
