Question: how do i connect my bluetooth to my fitbit charge 2?
Answer: Go to the Bluetooth settings on your phone and locate your Charge 2, then tap on it and select "Forget this Device"
Restart your phone.
Open the Fitbit app and enable All-day Sync by going to Account > Charge 2 > All-day Sync.
When a pop-up appears asking you to "Pair" your tracker, please do.
