Allow Mi band 6 to record HRV (heart rate variability)

One time I managed to connect my mi band 6 with bluetooth smart in heart rate monitoring section but it still only records heart rate but not HRV, Can you make it possible to record HRV also? Thanks

I completely agree.

HRV for Mi Band 6 was very useful.

Hello, we would need the implementators of our API e.g. Tools & Mi Band or Notify & Fitness to report RR intervals or SDNN through our Wearable integration APIā€¦ this is documented here https://sleep.urbandroid.org/docs/devs/wearable_api.html#send-various-body-sensors-data-hr-rr-spo2-sdnn
