 Devices in the LoRaWAN platform are implemented on Arduino boards with Dragino shields. The combined module as well as the basic configuration steps are presented in [[exploring_lora|Exploring LoRa lab]].
-Start by verifying the installation on your PC of the latest Arduino IDE. Drop the Arduino LMIC library in the corresponding folder. These tools are provided at the beginning of the lab. Open the example sketch ''example-code-rcte-iot-challenge.ino'' with Arduino IDE.
+Start by verifying the installation on your PC of the latest Arduino IDE. Unzip the Arduino {{ :arduino-lmic-master.zip |LMIC library}} and copy it to your sketchbook library folder as detailed in [[https://www.arduino.cc/en/Guide/Libraries]]. Then, download and open the example sketch {{ :example-code-rcte-iot-lab.zip |example-code-rcte-iot-lab.ino}} with Arduino IDE.
 Now you should configure your device with the same identifiers ''APPEUI'', ''DEVEUI'', and ''APPKEY'' as in the backend:
