Where is the bluetooth in the P1P

the bluetooth addition on the P1P sounds useful, possibly a hands off means of setting up the machine. Does anyone know where the bluetooth chip resides? I’m assuming in the new control interface and, if so, I might look at downgrading to that. Being blind the touch screen isn’t much use to me, but a button based system, at least I can memorise the key strokes to say unload and reload etc.

Any thoughts?
