Blaze is not syncing properly with iPhone

[Nikkibyerly1979]

I need to update my Blaze so that it will sync with my iPhone. I can't use the app because my Blaze won't sync and I can't find my Bluetooth dogle. Is there anything I can do besides buying a new Blaze?

Hello @Nikkibyerly1979, have a warm welcome to the Fitbit Community, it's great to have you on board. 

Since when have you experienced this issue? Is your app updated? Have you updated the iOS version on your phone as well? If so, I would like to suggest the following:

1. Restart your tracker by pressing and holding the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen. 
2. Plug in your tracker and make sure it's charging. 
3. Open the Fitbit app and try to sync your Blaze.

If this doesn't seem to work, let's try adding your tracker as a new device to reset the connection between your tracker and your phone. Don't worry, this won't delete any of the information previously stored in your account. 

To set up your tracker as a new device:

1. Make sure your tracker is still plugged in and charging.
2. Go to the Bluetooth settings on your phone and check if your tracker is on the list of paired devices. If it is, tap on it and select Forget this Device.
3. Restart your phone.
4. Open the Fitbit app and tap on the Account symbol at the top right corner of the screen, then tap on "Set up a New Device"
5. Choose your tracker and follow the onscreen instructions to continue
6. When the app asks you to replace your current tracker, please replace it and continue with the process.

I hope this can be helpful, give it a try and let me know the outcome!
