Wrong SpO2 values. How to solve it?

[AhmedAymanNegmm]

Hi

I am using example 8 on my MAX30102 to detect oxygen level, but I am getting very wrong numbers. values range in 10-100 and sometimes I get -999. Did anyone face similar issue and was able to resolve???

Was there ever a resolve here... ?

@FigsnApples I've fixed it. Please refer the below repo. I've explained it and I also attached the reference to the fix as well.

In my scenario, it was due to a cheap Chinese MAX3010 sensor

Have a simplified code analogous to basic readings example of MAX30101 library?

I am using Sparkfun's Max30101 - same deal with knockoffs on Sparkfun devices too?
