Bluetooth requirements for wii controls ?

Hey, i am today going to buy myself a wii to catch up to some good old wii games, but im also going to use the wii's sensor and controllers for dolphin.

So here is my question:

Will this bluetooth 2.1 dongle work with the controllers? or does it have to be a normal size and not a nano dongle?
