Firstly, check System Preferences>Bluetooth and click on the Advanced button. Make sure there is a tick against 'Allow Bluetooth devices to wake this computer'.
If there is and you are having this wake from sleep problem try this: System Preferences>Energy Saver and set 'computer sleep' to 'never'.
Some users (me included) have had the problem you describe intermittently. The Energy Saver 'fix' solves it for me until it hopefully gets properly resolved in a future OS update.

Thanks for the quick response. The Bluetooth was already set up like you suggested. As far as Energy Saver I've been tweaking that as well. I changed the setting from 3 hours to never, so hopefully that will work. And as far as the check marks in the boxes below, the only one I have checked is "Allow power button...sleep". Thanks again.
