This section provides a description of how to use the demo application to connect two configured board and communicate over Bluetooth. Bluetooth HFP is a simple Client-Server connection process with one side operating in the Audio-Gateway role and the other operating in the Handsfree role. We will setup one of the boards as a Handsfree server and use an android phone as Client. Once connected, we can transmit data between the two devices over Bluetooth

1. Perform the steps mentioned earlier in Running the Bluetooth Code section to initialize the application.

2. Give a name for the MSP430 using the SetLocalName. In our example we give it a name of hfpserver.
