I'm trying to read Versa Lite Watch heart rate using using the Bluetooth.

Hi guys,

i have developed a mobile application in react-native where i was trying to connect to Versa Lite watch and read the Heart Rate Services and Characteristics. I was able to connect and read the services and characteristics. But i wasn't able to know which services and characteristics belong to heart rate service. Generally all the BLE devices use the below Specifications to advertise the Heart Rate Features.

Services:

Heart Rate     org.bluetooth.service.heart_rate     0x180D     GSS

Characteristics:

Heart Rate Measurement     org.bluetooth.characteristic.heart_rate_measurement    0x2A37   GSS

Does Fitbit uses different Assigned Numbers for their heart rate sensor Services and Characteristics? Above assigned numbers i have got it from 

https://www.bluetooth.com/specifications/gatt/services/ 

https://www.bluetooth.com/specifications/gatt/characteristics/

Any help is greatly appreciated.

Note: I don't wan't to use Fitbit SDK, as my application scans for other devices like Samsung, Honeywell and other heart rate sensors. 

Thank you,

Fitbit don't currently provide direct device connections via BLE. The only way to access sensor data in realtime is via the Device SDK.
