Bluetooth classic/Connected GPS not working iOS8

[stephs2125]

Hello recently I tried using the GPS 'Run' feature (under exercise) but kept getting an error to check my Fitbit App (with no further instructions). I go to the app on my iPhone 8. It has no message or obvious error but will not allow my Blaze to connect to the phones GPS.  I then look under my bluetooth connections (under settings) and the Bluetooth Classic is completely missing (this has happened before) so I shutdown the Blaze, restart, and it is back.  However when I go to pair it to my iPhone there are two options under my phone bluetooth settings...Blaze and Blaze Classic.  It has connected automatically to Blaze but despite my phone and watch being right next to each other when I try to pair to the Blaze classic I get an error reading make sure the Blaze is turned on and in range (it is).  It will not connect to Blaze classic at all. 

So...now I cannot use my watch/phone combo to get GPS accuracy (route maps) for my runs. 

This is a feature I very much need and want. How to I fix this?  Any suggestions?

Nice to see that you're digging into the Forums @stephs2125, let me give you a warm welcome to our Community. 

Thanks for all the steps that you've done and for the details on your post. I'd suggest checking if your phone and Fitbit App are up to date. Then please try the following: 

1. Force quite the App and turn off/on your phone
2. Open Fitbit App, go to Account (upper right corner) > Delete Fitbit tracker from the Account
3. Open the Bluetooth Setting on your phone and delete Fitbit tracker from there too
4. Reboot Bletooth to make sure tracker is not there
5. Restart your tracker  a couple of times and Access back to Fitbit App > Account to set up your Fitbit tracker back
6. Turn on notifications and check if Connected GPS is working 
7. (If Connected GPS is not working please check: Why isn't GPS working on my Fitbit device?)

Bluetooth Classic feature is used only to control your music. Music control should work automatically after setting up your Blaze, so just follow these steps: 

1. Swipe to Settings > Bluetooth Classic > Pair. 
2. On your phone, navigate to the Bluetooth settings where paired devices are listed. Your phone will scan for available devices.
3. When you see Blaze Classic as an available device, tap it.
4. Wait a few moments for the 6-digit number to appear on your screen.
5. When the same 6-digit number appears on Blaze, tap Yes.
6. On your phone, tap Pair.

Keep me posted.
