Update the AR2 firmware from the app

Firmware updates fix problems and improve how the glasses connect. The XRAI app updates the glasses for you; it takes a few minutes.

When an update is ready

A red dot appears on your picture in the top-right corner of the app, and the menu under it shows Update AR2 Firmware. It only appears while your glasses are connected and an update is waiting for them.

Before you start

• Charge your phone and the glasses above 25%. The app won't start the update below that.
• Keep the glasses switched on, on your face or on the table next to your phone, until the update finishes.
• On a work phone with a security VPN, such as Microsoft Defender, the update can't reach the glasses' Wi-Fi. Use a computer instead: see Update the AR2 firmware from a computer.

Update the glasses

1. Tap your picture, then Update AR2 Firmware. Glasses Update shows the version on your glasses, the latest version, and both batteries.
2. Tap Update now. The app downloads the update.
3. When Connect to your glasses appears, tap Connect. Your phone joins the glasses' own Wi-Fi network to copy the update across. On iPhone, tap Join straight away when asked.
4. Wait while the app copies the update, then the glasses install it and restart. Don't turn them off.
5. When you see Update complete, tap Done. Your phone goes back to its normal network by itself.

If it doesn't work

• Update failed: tap Try again. A second attempt often goes straight through, especially if the first stopped while joining the glasses' Wi-Fi.
• If the glasses don't reconnect after the update, close the app, open it again and tap Connect when it finds them. If that doesn't work, reset and re-pair them.
• If the app update keeps failing, use a computer: Update the AR2 firmware from a computer.
