If you are trying to use your iPhone as a hotspot, but that is also the same phone you paired the Envision Glasses with, you can only connect to the internet by scanning a QR code.
For this to work, you need to make sure that the Personal Hotspot Screen on your iPhone is open and that the option Allow Other to Join is active. While remaining on that screen on your iPhone, you can then follow the steps to connect to a wi-fi network using a QR code. The QR code will have to be generated on a different device (either your computer or another phone/tablet), because you cannot exit the Personal Hotspot Screen on your iPhone during this process. You can find below the steps to connect to a wi-fi network using a QR code:
Step 1: Turn on the Envision Glasses and wear the device.
Step 2: Go to Device Settings.
Step 3: Now go to Wi-Fi.
Step 4: Go to Connect Wi-Fi. If you are not seeing this option, it means your Wi-Fi is off and you have to first double-tap to turn on the Wi-Fi.
Step 5: After double-tapping on Connect Wi-Fi you will hear a fetching sound. Upon completion, a list of Wi-Fi networks will be given.
Step 6: Swipe forward, or back, to scroll through the list of Wi-Fi networks.
Step 7: Double-tap on the name of the Wi-Fi Network.
Step 8: In this guide we assume you have not connected to this network before. You will end up on the screen to connect with the Envision app. Scroll forwards and go to Scan a QR Code. You will hear a sound which means the camera is active.
Step 9: Go to letsenvision.com/qr on your phone or desktop and fill in the password of the chosen Wi-Fi network.
Step 10: Generate the Wi-Fi QR Code.
Step 11: While you are wearing the Envision Glasses, look at the Wi-Fi QR Code, or point the camera located on the front towards the generated Wi-Fi QR Code. A processing sound is played when the QR code is detected.
Step 12: Once you are connected to the chosen Wi-Fi, you will be redirected to the start screen and you can start using the Envision Glasses features that require an internet connection.
