 * @file main.c
 * @brief BleTx Click example
 *
 * # Description
 * This library contains API for the BLE TX Click driver.
 * This example processes data from BLE TX Click, BLE TX Click 
 * Bluetooth® Low Energy compliant advertising transmission 
 * can be achieved by simply configuring the transmission power, 
 * data, and transmission - start trigger.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * Initializes driver and set performs the default configuration.
 * Configure Bluetooth Low Energy Beacons to transmit so-called advertising frames.
 * Configuration of the Eddystone URI, UID, or TLM 
 * Bluetooth Low Energy Beacons profile task depends on uncommented code.
 * Eddystone ( URI ) : broadcasts a URL of at most 15 characters 
 * that redirects to a website that is secured using SSL.
 * Eddystone ( UID ) : broadcasts an identifying code 
 * that allows apps to retrieve information from app servers. 
 * Eddystone ( TLM ) : broadcasts information about the beacon,
 * include battery level, sensor data, or other relevant information 
 * to beacon administrators.
 *
 * ## Application Task
 * This is an example that shows the use of a BLE TX click board™.
 * In this example, the application turns the selected advertising frames
 * ON and OFF for a period of 10 seconds.
 *
 * @note
 * For scanning BLE TX click board™ BLE Scanner is a recommended Android application 
 * and you can find it at the link:
 * https://play.google.com/store/apps/details?id=com.macdom.ble.blescanner
