Solution:

AWS is a well-known public cloud, which provide lots of service on the cloud, including EC2, Lambda, and RDS, etc. In this document, WISE-4000, WISE-4000LAN and WISE-4250 will use AWS IoT Core service in order to send the IO data to AWS easily. Then user can use the IO data on other services on AWS for further application. The connection topology of WISE-4000&4000LAN&4250 and AWS IoT Core is shown as below. As you can see, WISE devices will use MQTT protocol with certificate, and then deploy a policy to make each message sent to Core IoT MQTT broker. Finally, the customer can use external 3rd party MQTT client to check whether the connection is successful. Therefore, this document will instruct user how to do setting for above connection topology, then how to check whether the message sent from WISE device to AWS IoT Core is successful.
