Galaxy watch 4 sensor data

I am trying to develop wear os application that needs to read heart rate, step counter, ECG and spo2 data from the galaxy watch 4 classics.

As this is the first watch that is powered by wear OS, I am not getting sufficient documents and information. I even tried to get data through Samsung health but it says the device is not supported. Is there any documentation to get those data as I found most documents for Tizen OS only ?

Thank you

You need to address this on an Android Wear developer board.

The documentation for Wear Health Services is HERE but I don’t know where the Sensor API is documented I haven’t found that yet.

Samsung Health information was not available on Tizen OS either. On WearOS it is provided as complications but I don’t think the data is available only the display.
