Is it possible to access the LEDs and associated light sensors directly? What about all sensor data.

I am interested in accessing a lot of sensor data, in a more raw form than body detection and heart rate for example.

Is there a listing of the actual hardware sensors and access to them?
LED frequencies and light sensor  spectral response curves ?

Noting that there is some SPO2 functionality added to the Versa, I assume that there is enough different light spectrum to do that sensing. It would be great if we could access that.  Even an  SPO2 output would be ok, since you guys probably have done any signal processing for us.

Hi, we don't currently provide APIs which expose the raw heart rate sensor data.

What about the SPo2 output? you got me a variable yet?
