How to read real-time heart rate? does the SDK support Galaxy Fit 3

Hello.
Currently I want to use flutter to develop a mobile app to read the real-time heart rate data of Galaxy Fit 3. I observed that the Samsung health kit provides heart rate data, but I did not see the relevant data of real-time measurement (https://developer.samsung.com/health/android/data/api-reference/com/samsung/android/sdk/healthdata/HealthConstants.HeartRate.html). Is there any relevant method to read the real-time measurement data of heart rate? Does this method support Galaxy Fit 3?
Thanks for response.

Hello,
Welcome to this forum.

As far as I know, this is not possible.

Hi, this is possible since heart rate is a parameter that is free and follows the specifications of the BLE standard, just point to the standard heart rate features and services addresses and you will get them. For my part, I have only been able to read that parameter, but the other parameters such as hours of sleep and number of steps are apparently not free and do not follow the UUID addresses of the BLE standard.
