***How is heart rate data being captured for Bluetooth LE devices using Validic's mobile library?***

When the process to capture Bluetooth LE heart rate data from a clinical device is initiated using Validic's mobile library, readings will be captured over a period of 60 seconds. After that 60 second period, a minimum, maximum, and median heart rate will be calculated and saved in the expanded data of the biometrics record that gets created in the Validic API.
