HKworkoutSession Heartrate updating freqency

Question

I am doing some pre-learning about watchOS2 and having a question about HKworkoutSession.

I am able to start HKworkoutSession and read heart rate data from sensor. But how could I control data updating frequency?

In the build-in heartrate measuring app on the apple watch, heart rate updates approximately per 5 second.

Is there any way to decrease the frequency?

Thanks

There is no way to directly control the frequency of heart rate readings on the watch.

Thank you for your answer. Could you confirm that current updating frequency for heartrate sensor is 5 seconds?Because I just kind of measured it manually with a stop watch. – Nevermore Jul 08 '15 at 23:45
