Welcome, Peter 
 BLE introduces a new way of communicating. The smartphone will act as a Central, while the board will act as a Peripheral.
The peripheral has to have a service with characteristics which can then be accessed from the central. In the smartphone, you have to: 
 
 Discover your peripheral and its services 
 Find its characteristics 
 Write a value to a characteristic 
 
 The peripheral then will be notified when the write occurs, so you can take further actions. 
 You can find many examples on the SDK files.
