By taking a look at available APIs I haven't seen this option.
What I mean here is that for e.g. measuring pulse, there is an algorithm that converts some raw sensor data that is interpreted/processed and converted into pulse. I'd like to retrieve that kind of (raw) data.
I wanted to perform some experiments with creating my own metrics (other than the ones available) and I wanted to experiment with raw sensors data rather than pulse, SpO2, etc.
Is that in any way possible?
