Hi, you're having some problems

[sd1435728]

When I set captureSession.sessionPreset = .low, it takes about 10 seconds or more to retrieve heart rate data. When I set captureSession.sessionPreset = .medium, it only takes about 4 seconds to get the data, but the data seems to be less accurate. Is there any solution to this problem?

Hey @sd1435728 !

Maybe you can try increasing the size of VideoSpec
let specs = VideoSpec(fps: 30, size: CGSize(width: 300, height: 300)) in PulseViewController.
