Fitbit Charge HR Error : FBBluetoothErrorDomain error 18

posted Dec 3, 2017, 10:11 PM by Jose Marie Maquinay
My trusty Charge HR died over the weekend due to bad firmware update (I blame the Philippines poor internet connection services..), my iPhone wont see it, and keeps giving me a "FBBluetoothErrorDomain error 18". A little Googling showed me the way :

As we've mentioned the reason why you are seeing this halfway full bar on the display of the tracker is the firmware update that unfortunately got stuck! With that in mind, we would like you to try some steps that we believe might be helpful: 

1) Open the BT settings (if the tracker appears unpair it from the list) and turn the BT off, 
2) Open the Fitbit App - Click on Account -> Charge HR -> click on the trash bin (top right corner) or scroll down and click Unpair 
3) Once removed from the App, restart both the tracker ((link: http://help.fitbit.com/articles/en_US/Help_article/1186) help.fitbit.com/articles/en_US…) and the phone, 
4) Turn the phone and the BT On and open the Fitbit App -> Account -> "+ Set up a new device" and follow the instructions on the screen to pair the Charge HR back. The update should start automatically. Please keep us posted!"

In my case, only unpaired the the Charge HR from the phone, and the update finally continued! Now it's counting again my mediocre steps. :D
