/**
 * @brief This example demonstrates Zigbee windspeed sensor.
 *
 * The example demonstrates how to use Zigbee library to create a end device wind speed sensor.
 * The wind speed sensor is a Zigbee end device, which is controlled by a Zigbee coordinator.
 *
 * Proper Zigbee mode must be selected in Tools->Zigbee mode
 * and also the correct partition scheme must be selected in Tools->Partition Scheme.
 *
 * Please check the README.md for instructions and more detailed description.
