Just so you know where it is, the antenna used to communicate over Bluetooth is located here. You can kind of see it if you hold the board just right in the light. It looks like a square squiggle snake thing.

The actual hardware that does the Bluetooth communications is part of the main microcontroller (processor). This is just the antenna part, so maybe don't wrap that area in tinfoil or go drilling holes in it or something.
