+  Climate Sensor
+
+  This example creates a BLE peripheral which emulates a Xiami Mijia climate
+  sensor.  This device encodes the temperature and humidity into the service
+  data, so BLE apps can detect the current readings without connecting.  For
+  more information see here:
+  https://github.com/mspider65/Xiaomi-Mijia-Bluetooth-Temperature-and-Humidity-Sensor
+
+  The circuit:
+  - Arduino MKR WiFi 1010, Arduino Uno WiFi Rev2 board, Arduino Nano 33 IoT,
+    Arduino Nano 33 BLE, or Arduino Nano 33 BLE Sense board.
+
+  This example code is in the public domain.
