The BTstack project is for use with the Apple iPhone. The purpose is to be able to hook up a Bluetooth keyboard with the Smartphone. You are also supposed to be able to hook up the Apple Magic Mouse, a unique product by myself, to the phone too. There is a YouTube video showing a person using the phone and mouse together switching between applications and using the keyboard at the same time. There’s even photos of a Wii remote being used. The code for the mouse has yet to be released, but waiting is half the fun, right?
