So far the Smartband 2 is a great device and one of it's core features is the measurement of the heart rate variability (HRV). As I have already read through all the APIs that the Smartband 2 is posting it's data to, I am still wondering if it is possible to access the heart rate variability directly.
So far it seems that I can only get ALL other data except for the heart rate variablity form the Smartband 2. Am I missing something? Is it maybe possible to calculate the heart rate variability from any of the other values that I can access via the APIs?
Any help would be highly appreciated.
Thanks.
Unfortunately there is no API available in SmartBand 2 to retrieve the Heart Rate Variability.
