The bluetooth wireless option is totally pointless if you buy the Smart USB Speakers and intend to use the USB digital audio, which must be run to the computer over a USB cable.
You cannot use the bluetooth option to wirelessly send digital audio to the board speakers, even though bluetooth is bidirectional, and commonly used on phones to send audio to an earpiece. Bluetooth is for the touchscreen only.
If you run a USB cable for the speakers..... you can also plug the touchscreen into the speakers, and so the board and speakers share one wire to connect to the computer. In this case the Bluetooth is a waste of money.
