NRA allows us, in case of bike accident, to locate the injured person through the Sigfox network. It also improves visibility on the road.

Works for me - it is different code on the ATTiny85.
As I mention in the write up, if your dicrotic notch is particularly pronounced - as it is in young people - it can confuse the peak detector and you can get a pulse rate which is double what it should be. Make sure you are getting a clean waveform displayed - warm fingers help. Look at the filtered. IR waveform to see if you are getting a false peak. You could increase the strength of the second stage filter which should help.
Yes, should work with no problems.
