5. Update!

Apple's Bluetooth stack—the set of software that controls the radio—isn't without its occasional quirks. Sometimes brand new versions of iOS introduce compatibility problems and sometimes they fix them. If you're having Bluetooth connectivity problems, however, you're better off upgrading than not. If it's already broke, the update is your chance for a fix.

  1. Make sure you have a recent iCloud backup.
  2. Launch Settings from your Home screen.
  3. Tap on General.
  4. Tap on Software Update.
  5. Tap on Download and Install.

  6. Enter your Passcode, if prompted.
  7. Tap Agree to the Terms and Conditions.
  8. Tap Agree again to confirm.
  9. Tap Install Now to begin the update.

Once you're done updating, try to connect again. If it works, awesome. If not, repeat step 3, above, to forget and reconnect with the Bluetooth device. If even that doesn't work, there's more to try!
