What bluetooth chip in iPad?

[albebaubles]

Does anyone know the bluetooth chip employed in any of the later generation iPads?

I'd like to look up the command mode methods for the specific chip.

No, nothing to do with App Store -- I need to boost the power index on the BT chip to overcome interference issues with my medical devices.

Thanks
