If your Fitbit device does not return any heart rhythm results after a few minutes, this probably means there is a problem with your Bluetooth connection.
To verify if you have Bluetooth connection, check if your Fitbit device is synced:
- Open the Fitbit smartphone app
- With your watch nearby, in the Fitbit mobile app, tap your profile picture in the left upper corner and select your device image
- Check if your device recently has been synced (this is shown at the top of your screen, next to your device image)
Your device has not been syncing the last few minutes? Try the following troubleshooting steps.
