Description: The Protocol Master Tutorial main routine initializes the system by initializing the ISR, timer, and protocol. Then the protocol is set to a master role. <a class="el" href="protocol_8c.html#a19">master_bind_mode()</a> is used to bind to a slave device. After binding, it continuously checks for a button press or goes into <a class="el" href="protocol_8c.html#a20">master_data_mode()</a>, which looks for a data packet from the slave device and calls <a class="el" href="main_8c.html#a7">app_unload_packet()</a> if a packet is received. If a button is pressed, a data packet is sent to the slave device.<p>

Returns: Void </td>
