Troubleshoot Fitbit Sync Issues


If a participant’s Fitbit device is not syncing properly, it can disrupt data collection by the Summa System. There are several steps a participant can take to re-establish Fitbit device connection.

For information from Fitbit on troubleshooting device sync issues, use the following link –

Try the following steps to resolve sync issues:

  • Force quit the Fitbit mobile app
  • Go to Settings > Bluetooth and turn Bluetooth off for 15 seconds then back on
  • Open the Fitbit app
  • If the Fitbit device still won’t sync, restart the iPhone
  • Open the Fitbit app
  • If the Fitbit device still won’t sync, restart the iPhone and Fitbit device and wait 10 minutes

If these steps do not re-establish connection, participants can escalate sync issues directly with Fitbit via the Fitbit support page –

If serious sync and connection issues persist, participants may consider the following options:

Reset Network Settings
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including: previously connected Wi-Fi networks and passwords, recently used Bluetooth accessories, VPN, and APN settings.

Remove Device
In the Fitbit mobile app, select ‘Remove this Device’. Note: This will force you to perform initial device setup again to re-establish connection.

Device Factory Reset
Perform a factory reset by tapping Settings > About > Factory Reset on the Fitbit device. Note: Factory reset will delete all personal and app data associated with the Device. You will have to go through initial Fitbit device setup again via the Fitbit mobile application.
