This example shows how to make a normal scan 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
