@brief This example demonstrates Zigbee temperature and humidity sensor Sleepy device.

17

18

The example demonstrates how to use Zigbee library to create an end device temperature and humidity sensor.

19

The sensor is a Zigbee end device, which is reporting data to the Zigbee network.

20

21

Proper Zigbee mode must be selected in Tools->Zigbee mode

22

and also the correct partition scheme must be selected in Tools->Partition Scheme.

23

24

Please check the README.md for instructions and more detailed description.
