With some digging, I have found how to get a stack of FIT files, which appear to be the raw low level data (not sure, can't see inside them yet).
How do I get this stack of 42 files into a single csv or excel file?
(I am using the vivoactive 4, looking to get a csv or excel showing pulse and SPO2 level, every minute, e.g. date-time, pulse, SPO2)
Thanks!
