On-board Bluetooth
The witespy board can be equipped with a HC06 bluetooth module on the bottom side of the board. However, a diode, which is needed for the on-board bluetooth module to work, is not populated. Its location is shown in the photo below. In principle any diode which fits on the pads can be used, but preferably a Shottky diode is choosen. The "original" type is PMEG3010ER. A possibly simpler solution is to just short circuit the two pads by e.g. soldering a piece of wire across them. However, the communication via the UART port wouldn't work then anymore, i.e. this should only be done if one is not going to use the UART port anytime.
For further info on the HC06 bluetooth module, and its installation and configuration, see Bluetooth Module HC06.
