 * @brief Template project main file for dynamic BLE and Zigbee.
 *
 * This file contains a template for creating a new multiprotocol BLE + Zigbee application.
 * In terms of BLE, it has the code necessary to wake up from button, advertise,
 * get a connection, restart advertising on disconnect and if no new connection was created
 * go back to system-off mode.
 * In terms of Zigbee, it has the code implementing the Range Extender Device - a
 * simple router which is just relaying packets.
 * It can easily be used as a starting point for creating a new application, the comments identified
 * with 'YOUR_JOB' indicates where and how you can customize.
