|
* @brief This example demonstrates Zigbee temperature sensor.
|
|
*
|
|
* The example demonstrates how to use Zigbee library to create a end device temperature sensor.
|
|
* The temperature 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.
