Sleep stages & resting heart rate

[Chast1]

1st day I wore my Fitbit it recorded Sleep Stages and Resting Heart Rate.  In the week since it has only recorded simplified sleep details and no new testing heart rate.  Also it is not showing other heart rate data.  Bluetooth is synced.  iPhone recognizes Fitbit.  Settings on device says that heart rate is on.  Screen is dark on heart rate bpm.  Have tried all suggested troubleshooting.  Any Ideas?

Nice to see that you're digging into the Fitbit Forums @Chast1, let me give you a warm welcome to our community.

I noticed that you received help from our support team to fix the issues with your sleep and heart rate tracking. Thank you for the troubleshooting done! 

Make sure to wear your Fitbit on top of your wrist.  For best results, the back of your device should be in contact with your skin for features like heart-rate tracking and detecting when you’re wearing your device.

Remember that there are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

For more information about why you see your sleep pattern, tap or click the sleep record that shows your sleep pattern. Are you getting sleep pattern details?

I'll be around, keep me posted.
