Sending raw ppg to a server

Watch Face Studio
1

Hi, I am new to developing applications on a smartwatch and I would like to know if the samsung galaxy watch 4 or higher can send raw data from the various meters (PPG, ECG, …) to a server without the smartwatch being connected to a pc at any time, any galaxy watch 4 or higher would work for me?

Watch Face Studio cannot do that. You need to develop this with Android Studio.

So is it safe to assume that I can access my smartwatch sensors natively from my app thanks to Samsung Privileged Health SDK?

You need to use Samsung Privileged Health SDK to get PPG and ECG data on Galaxy Watch 4 and above. This is the only way.
To use the sdk you need the partnership. For detail check here: Samsung Privileged Health SDK | Samsung Developers
Yes, this is 100% safe to use.

To send data to server, use this guide: 在 Wear OS 上傳送資料並同步處理  |  Android Developers

Thanks.

Thanks for responding, I’ve been looking around the forum to see if there was anyone with my same problem, and I saw something very similar to what I wanted to do, is the Samsung SDK really necessary if I want to collect raw data from PPG and EDG from a modern galaxy watch? i cant do it with only Android Stdusi?

If it is not needed, what is the SDK for and who can use it?

I say this last because I don’t think anyone can use it, right?

Not only do you not need it, It won’t work with Wear based watch faces. The Android Health SDK was for the Pre Galaxy Watch 4 watches that used Tizen OS

You can access sensors directly using Android Studio if you want Raw data

Thank you so much Ron, you helped me a lot.

I have one question remaining. ¿Can i use in my app the wifi module?

My app needs to send data to a server, and I need the smartwatch to be able to do this on its own, without the help of a phone.

¿Can i do it with a galaxy watch 6?

I don’t know how to do it but I know you can do it.
