Connect your Checkme O2 Max over Bluetooth
Pair your Wellue device in one tap, straight from your browser.
Updated 2026-06-28
Wellue Sync talks to your Checkme O2 Max directly from the browser using Web Bluetooth — there is no app to install and nothing to upload manually.
Web Bluetooth works in Chrome, Edge, and other Chromium-based browsers on desktop and Android. Safari and Firefox do not support it yet.
Pair the device
- Turn on your Checkme O2 Max and make sure it is not connected to the Wellue phone app (a device can only be paired with one client at a time).
- Open the dashboard and click Connect via Bluetooth in the toolbar.
- Pick your device from the browser's pairing dialog and confirm.
When the connection succeeds the status pill turns green and Download History becomes available.
Troubleshooting
- No device in the list — confirm the device is awake and unpaired from the phone app.
- Connection drops — keep the device within a couple of metres of your computer during sync.
- Button is disabled — you are already connected; jump straight to running your first sync.
