I also using an onboard bluetooth but its a Atheros from Asus P9X79 Pro.
hmm this maybe a dumb question but did you Hold 1+2 long enough for the drivers to install and sync?
What happens is when you successfully installed the drivers release 1+2 button and your Wiimote will vibrate and connect to Dolphin.

That link was helpful to get my Wiimote working on first attempt.
