Hi Victor,

Thanks for your comments.

If you are looking just using alexa it would be simpler. In the header file you need the following.

AWS Root CA, AWS device cert, aws device key download from aws console.

#define AWS_IOT_ENDPOINT " from aws shadow"

// The MQTT topic that this device should publish to

#define AWS_IOT_TOPIC "$aws/things/" DEVICE_NAME "/shadow/update"

#define AWS_IOT_TOPIC_SUB "$aws/things/" DEVICE_NAME "/shadow/update/delta"

Hope this explains
