This example shows how to make a normal limited with Bluetooth module Pro, printing number of discovered devices and storing them into SD card.

Required Materials

1 x Waspmote 1 x Battery 1 x Coin battery 1 x Bluetooth module Pro 1 x Bluetooth module antenna 1 x Expansion board (if socket 1 is used) 1 x SD card
