/* @section Main Application Setup
*
* @text Listing MainConfiguration shows main application code.
* To run a HFP HF service you need to initialize the SDP, and to create and register HFP HF record with it.
* The packet_handler is used for sending commands to the HFP AG. It also receives the HFP AG's answers.
* The stdin_process callback allows for sending commands to the HFP AG.
* At the end the Bluetooth stack is started.
