Sense won't connect to my phone's Bluetooth anymore

The app updated and my sense wouldn't sync properly, so I tried to disconnect the Bluetooth. When I went to connect the app, my phone wasn't recognizing it. It still recognizes my watch though.

Hi there, @Happy312. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Sense and your time in trying to troubleshoot it. 

In addition to the steps you've done so far, please try the following in the order listed:

  • Unpair your Fitbit device from your phone's Bluetooth and Fitbit app.
  • Unpair other Bluetooth devices that you may also have paired to your phone's Bluetooth settings.
  • Force quit the Fitbit app.
  • Turn off other Bluetooth connections when not in use. This can help to prevent connectivity issues or Bluetooth interference.
  • Shut off your phone and turn it on after 1-2 minutes.
  • Turn on the Bluetooth on your phone.
  • Plug it into the charging cable and open the Fitbit app.
  • Set up your Fitbit device.
  • If there is no connection, restart your Fitbit device.
  • Once your Fitbit device is paired and syncing, please proceed to set up your other Bluetooth devices to your phone again. 


Before trying the above, please be aware that most Fitbit devices store up to 7 days of detailed minute-by-minute data. If you wait longer than 7 days before syncing, you may only see the most recent week's detailed data. Summary data (calories, distance, steps, and floors) will be stored for 30 days. Nevertheless, if your Fitbit device was unpaired from your Fitbit account during this period of time, neither the 7 days can be recovered or restored.

These steps do not work.  I have followed them multiple times. I am able to get the 4 digits on the Sense display.  The Fitbit app then says "connecting to Fitbit".  This message never changes. Then there is an error message "Something went wrong.  There was an error while trying to pair your device.  Abort. When I check my bluetooth devices the Sense is paired and I can receive messages from my Iphone.  However, the fitbit app is NOT paired.  Please suggest another fix.

Hello there, @Marybawesome. Thanks for stopping by in the Fitbit Community Forums and sharing the details about the issue with your Sense.

I appreciate you've taken the time to try the steps I shared above. As our last resort, I'd recommend performing a factory reset on your Sense. To do so, on your Fitbit device, open the Settings app > About > Factory Reset.

Once the above has been done, you can now proceed to set up your Sense again by following the steps provided here How do I set up my Fitbit device?

Take into consideration that a factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account and your applications, alarms, etc.

Does anybody bother to test these updates before rolling them out and causing all these issues? Having to mess around with all these things to try to get a product back to a working state is ridiculous and a complete waste of time.

The Bluetooth sync issues started way before the new app rolled out.

Ok. Your point is what? My question is not valid because it does not fit your time period?

Easy there, easy. I was only stating that the Bluetooth sync issues have nothing to do with the recent FitBit app update. Many people started having sync issues long before the new app rolled out.
