AWS IoT Greengrass Version 1 entered the extended life phase on June 30, 2023. For more information, see the AWS IoT Greengrass V1 maintenance policy. After this date, AWS IoT Greengrass V1 won't release updates that provide features, enhancements, bug fixes, or security patches. Devices that run on AWS IoT Greengrass V1 won't be disrupted and will continue to operate and to connect to the cloud. We strongly recommend that you migrate to AWS IoT Greengrass Version 2, which adds significant new features and support for additional platforms.
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.
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.
