• As above really - yes, it is possible. The VC31 in KickStarter bangle 2s didn't advertise the capability but the VC31B in the new batch does. As far as I can tell there's not a huge difference though so the first batch may also be fine.

    But it's not like there's a 'blood oxygen saturation' value in the sensor that we're just not reading. It has to be calculated from raw data so the value is going to be a bit of a guesstimate.
