Guys, Do you have any idea to read heart rate from the M6 health band via Arduino Bluetooth ?
What documentation do you have for it?
I just looked up the M6 band. They cost a couple of quid from China. So just make the value up, probably what they are doing anyway.
Kidding aside. It's transferring data between the watch and a proprtitary mobile app. You could connect the app to a PC and read the memory to see what data its getting back and the format etc. But I think your going to have difficultly pairing with the band itself.
You would be better off looking for a generic heart rate monitor that broadcasts its result over Bluetooth and/or ANT and has some documentation.
Or make your own monitor.
