O2Ring S (new model 2024/2025) not detected by Sleep Viatom O2Ring Advanced add-on

Device: Samsung Galaxy Z Fold7

Android version: Android 16 (One UI 8.0)

Sleep as Android version: latest (Play Store)

Add-on version: Sleep Viatom O2Ring Advanced (last updated September 2024)

Hardware: Wellue O2Ring S (new 2024/2025 model — USB-C, 1-second sampling, one-piece design)

Problem:

The O2Ring S is not detected by the add-on at all. The ring is powered on and worn (BLE active automatically on body contact). All Android permissions are granted: Nearby Devices (Bluetooth), Background operation. The ring connects and works perfectly in ViHealth app.

The add-on scan shows no devices. Tested with both Web-APK and Play Store version of SAA.

Important: I found this existing thread about the same issue with the O2Ring Pro: O2ring-Pro issues

The original O2Ring (O2R22) reportedly works fine with the add-on. The S/Pro models appear to use a new BLE protocol revision not yet supported by the add-on — confirmed by community reverse-engineering: GitHub - farolone/wellue-o2ring-protocol: Reverse-engineered Bluetooth Low Energy protocol documentation for the Wellue O2Ring pulse oximeter · GitHub

Request: Please update the add-on to support the new O2Ring S BLE protocol, or confirm whether support is planned.

Hi @Teh_Hah, the addon is not ours, but was created by the Chakaponden developer team. We are not sure, if they read this forum, so maybe better to let them know directly on their support, if there are some issues with the addon.
