Module 4: Interacting with client devices in an AWS IoT Greengrass group

This module shows you how local IoT devices, called client devices or devices, can connect to and communicate with an AWS IoT Greengrass core device. Client 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 client device sends a Hello World message to another client device in the Greengrass group.

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

Before you begin, run the Greengrass device setup script or complete Module 1 and Module 2. This module creates two simulated client devices. You do not need other components or devices.

This module should take less than 30 minutes to complete.
