Fibit API, HRV Research, PPG Data

[MediPort]

To whom this may concern,

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.

I am having the same question. I was hoping to get the data with an archive download, but so far no luck. Did you get any useful information from partnerships@fitbit.com?
