Galaxy Watch API, HRV Research, PPG Data

Hey Guys,

I am writing as I have several questions regarding your PPG sensors and in particular your API as I would like to use your HRV data for research purposes.

  • Do the PPG sensors found within your device take readings 24 7 and at what refresh rate i.e. 50Hz?

  • If so, then would I be able to retrieve this data from your cloud database

  • If not then can I, upon the users request, override this protocol via the API to make sure that the PPG sensor is operating constantly

  • What file format does the data come in and what exact metrics are contained within the file i.e. IBI, SDNN, RMSSD?

I look forward to your response.
