If there were a hardware problem BT wouldn't be working at all. BT can be wonky. When you say it isn't working, do you mean it doesn't automatically connect with a device (like your mouse) or that when you attempt to manually connect it fails? (This being why I always have a wired keyboard an mouse on hand.)
Have you opened the BT preference tab, deleted your mouse configuration and try re-pairing it? Note: make sure the mouse is on (look for the green light) before initiating the pair. This may be one of the biggest reasons BT seems to be broken - batteries dead.

For the iPhone I have removed the device and attempted to "pair" again, several times. I would get a message on my iPhone that "this device is not supported", meaning the MacBook is not supported. Which is crazy in itself, but also it was working a few days before.
But the next day, the iPhone worked fine and the mouse stopped working. I tried several times to pair the mouse. I didn't have to remove it because the mouse did not shop up on the BT list of devices on my MacBook. I was never able to add the device. Rebooting the MacBook didn't seem to have any effect with either device.
But that was then and this is now: This morning I opened up the MacBook (resumed) and all three devices now work via BT. All devices were purchased new since Nov 2012 and all updated to the most current OS. All devices were replacements for previous versions of the same devices.
