Question Only BPM available with WearOS health services?

[Poppa-Stylez]

Hey folks,

I'm trying to trigger/access SPO2 and access other vitals on my Samsung Galaxy Watch 4 and am following the only documentation i can find, which is the Google Health Services for WearOS: https://developer.android.com/training/wearables/health-services

I noticed a lot of DataTypes weren't working, so i ran

val capabilities = measureClient.capabilities.await()
Log.d("Capabilities", capabilities.toString())

And got back

Capabilities: MeasureCapabilities(supportedDataTypesMeasure=[DataType(name=HeartRate, timeType=SAMPLE, format=1)])

Is BPM the only supported DataType and if so, how is everyone building apps for Galaxy Watch 4 with access to vitals? Is there any doco I can follow?

Thanks!

Galaxy Watch 4 and all Health features fall under Samsung Health SDK...

Just looking at the development process listed here: https://developer.samsung.com/health/android/data/guide/process.html

Partnership with Samsung Health team is requires before using the SDK.

Then further down:

we will not be accepting any applications for the Partner Apps Program at this time.

So I'm assuming this option isn't available? Also, it didn't look like there was the ability to invoke a read from a sensor (such as SPO2), but rather access previous SPO2 reads from a repository. Finally, i was hoping to not have to wait for the data to sync with the phone prior to being able to access it. i.e. I wanted to push data into the cloud from the cellular version of the watch itself.

Is any of this possible at all?

If you have experience in reverse engineering apks, reverse engineer Samsung Health, Android manifest will have permissions to access sensors and the dive further more to see how the SpO2 logic is written but you might get some headache since it won't be easy since many things are obscured already...

(In this case, I suggest you go for older versions because they might be less obscured)

Good luck

Ps. If you need Samsung health sdk, I attached it for you...

I feared reverse engineering was going to be the answer! Will start looking into it. Thanks for your help!
