I recently took apart my old, barely working (but now not working
) 13" macbook. To my surprise, the bluetooth module not only has USB, but also labeled MOSI, MISO, CLK, and CSB pins. It also has CIF0 and CIF1, but I have no idea what these are. Has anyone used one of these things before? I tried looking up a datasheet, to no success, and I don't imagine the SPI interface is intuitive. If it helps, the PN on the RF cage is A1114, and I see the "anatel" brand name. I can post a picture if it will help.
