Hello! I just bought the amazfit band 5. Wich app shall I download? Tools & Amazfit or Notify & Fitness? Or it doesn’t matter? Thank you in advance and congratulations for the excellent work.
Mi Band/Amazfit is a closed system and integration is possible only because of heroes like Matteo of Notify & Finess and Zdenek Horak of Tools & Mi Band… They sniff the hex code and find the hidden interfaces in that mess…
Even Mi Band/Amazfit is able to track your SPO2 data and show them in the app, there does not seem to be a method which would provide SPO2 so that Tools or Notify apps could read it…
Still Matteo of Notify & Fitness was able to get at least raw LED data from the SPO2 sensor - there is still a long way to go to get SPO2 % from the intensitity of the light signal on the sensor…
So we cooperated with Matteo - he prepared a special version of Notify with the raw data collection and we have tracked SPO2 using a second device compatible with Sleep as Android and compared the raw data from Mi Badn with the SPO2 values from the other device in a hope to find a reliable function to get SPO2 data from the raw LED data…
It is quite a cumbersome task as you can see there are lots of thinks which can go wrong and although having maybe an hour of data we have not been able to find a reliable way to determine the SPO2 % from the raw LED signal yet :(…
Did you try that on a person with high SPO2 variability? I am not an expert, but it seems to me that the precision of oximetry readings by the bands is really bad. Everything will look like a noise.
The only way it’s seems is to corelate the readings during high variability of the oxygen which occurs for example during airplane flight.
