I’ve recently been having an issue with the Fitbit One. The fitbit is an electronic pedometer/sleep tracker, with nice graphical display and syncs to your mobile device /computer, showing your stats online.
All of a sudden the fitbit stopped syncing with my HTC One M8.
Fitbit’s website has several instructions for fixing the issue, ranging from force closing and uninstalling the app, to resetting the device.
Unfortunately none worked for me. I’ve even emailed their support team with no reply.
However I did find a solution, going into the Bluetooth settings and renaming the device.
My guess is that changing the name forced the devices to resync.
