When I first got my Fitbit HR it paired with no problems to my Droid Mini. My fitbit now wants to do an update and it kept saying that the connection was lost between it and my phone. I decided to unpair the fitbit in hopes that would work. Now I can't get my Fitbit to pair with my phone. The fitbit shows up as an available device, but a error pops up that says "Couldn't pair with Charge HR because of incorrect PIN or passkey." Help!
