@johan_m_o: as far as I understood its about lat/lon distance calculation and just accidentaly the same factor as km/mi for our distance from equator.
@HughB: v0.03 really made the difference:
Phone 5,40km, Bangle 5.4km!! :-)
Also steps got much better with 2v11: Mi3-band (worn besides bangle) 8000, Bangle 7842. Thats about 2% differnce, wich is quite ok (and also all the error could come from Mi3, we dont't know)
Still heartrate is completely broken for me. As said I plan to dig deeper into this soon.
Is there already an recorder for raw data of the HR sensor? Otherwise I would need to start with this. Shouldn't bee too difficult with the accelerometer recorder as an example I hope.
Update: Typing the above text brought step counter to 8240.
So people: do particiapte in forms! - as good as any exercise ;-)
