I needed a Bluetooth keyboard for my Raspberry Pi, and as I use the MacBook Air M2 and the iPad Pro with Magic Keyboard, I know that I love those flat keys with little travel. But the only ones I could find were Apple or “for Apple”. When doing some research why the answer was a bit surprising. Not the keyboard layout would be the problem, but the fact (?) that Apple uses some specific Apple Bluetooth protocol.
I have taken the risk, and the keyboard works fine with the Raspberry Pi. So this experience raised the question: does Apple use a specific interpretation of Bluetooth? If so, what is it? If not, why do people say so?
