Here is what fixed mine. Several others followed my post on this and have had success as well. Let me know if it resolves the problem.
1. Go into settings on your iPhone and select Bluetooth
2. Look on the list of devices and see if the Charge HR (or the device that you have) is listed. If it is select the device and choose “forget this device”.
3. Turn Bluetooth off on your phone
4. Have your FitBit in hand. Open the FitBit app on your iPhone and as it syncs it should tell you that there is an update. You have to select update now and this should end up downloading the new software as well as sync with your Charge HR. This may take a little while.
*Note*
If the update doesn’t download the first time, definitely try it again as it may be stuck from the previous time.
I hope this is helpful for you.
Good luck !🙂

I have the most recent updates on both my iPhone 6s and Fitbit app. I had the charge 2 but returned it because it wouldn’t sync. I also couldn’t get it to synch using my laptop. It kept losing the signal so there must be an issue with the Bluetooth itself.

1) I purchased an Alta on 24th September and have not been able to sync, update etc since purchase.
2) Fitbit Alta
3) 11.0.2 (15A421)
4) Optus 29.0.1
This issue means i cannot use the Alta, I am ready to return it to the shop for a refund as it is 'not able to be used as intended when sold'

Over the last three days I have been unable to use the fitbit due to the FBBluetoothErrorDomainerror18.
Fault first started on 12-10-2017 (Never gone away since 😞 )
Iphone 6 version 11.03
Fitbit Alta HR (Purchased August 2017)
Network BT
It was working fine but after charging the Fitbit it went in to lockout and all I get on the screen is a series of dots set out in a diamond shape.
Cant do anything with it and it wont work, useless the way it is currently.
Tried all below items and its still not working.
-Re-booting phone
-Tried pressing the little button on the usb plug.. (if that's what you call it and does it really do anything)
-Forgetting bluetooth connection and then reconnected
-shut all programmed down and re-booted phone
-logging off and back in of the fitbit App.
-Up dated the fibit App
-Tried to replace fit bit but will not connect, gives a code on the fitbit but will not allow the phone to connect, just keeps sending a new code.
Apart from returning it to where we brought it from that's the only thing left.
Please advise.

I have not gotten this error but my charge 2 stopped getting text and phone notifications yesterday 10/14/17.
It will sync info but that’s it. I have an iPhone 8 plus (AT&T)running IOS 11.0.3 and I have the latest update from Fitbit. Everything worked great till yesterday. I have to turn phone to silent at work and depend on the notifications on charge 2 throughout the day. This is very annoying. I hope this problem is fixed very soon .
