Smartband 2 Access heart rate variability

Question

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.

Answer 1

Unfortunately there is no API available in SmartBand 2 to retrieve the Heart Rate Variability.

Answer 2

Both sets of the Google Fit APIs work with three types of data: Public data types, Custom data types, and Shareable data types. SmartBand 2 provides the following Public data types to the Google Fitness Store:

• google.step_count.delta (steps)
• google.heart_rate.bpm (heart rate in bpm)
• google.activity.segment (sleeping, walking, running)
