I have to be able to buy the adapter to the Apple Wireless Keyboard with raspberry pi use and it works flawlessly. In connection 1. you have to type in the PIN code 1234 on the keyboard and that's it. The only thing that can interfere with, is that you wait about 30 seconds after the start of Raspi must begin to respond to the Raspi to commands from the keyboard. Since I live in a pretty little apartment, I can not report on maximum range of the adapter.
