Module 4: Interacting with Devices in an AWS IoT Greengrass Group

This module shows you how AWS IoT devices can connect to and communicate with an AWS IoT Greengrass core device. AWS IoT devices that connect to an AWS IoT Greengrass core are part of an AWS IoT Greengrass group and can participate in the AWS IoT Greengrass programming paradigm. In this module, one AWS IoT Greengrass device sends a Hello World message to another AWS IoT Greengrass device in the AWS IoT Greengrass group:


                AWS IoT connected to an AWS IoT Greengrass core, which is connected to AWS IoT Greengrass device #1 and
                    AWS IoT Greengrass device #2.

Before you begin, make sure that you have completed Module 1, Module 2, Module 3 (Part 1), and Module 3 (Part 2). You do not need other components or devices. This module should take less than 30 minutes to complete.
