Overview
The Greengrass Reference Implementation is a fully functional, deployable AWS IoT Greengrass gateway running on CompuLab IOT-GATE-iMX8 hardware. It scans for nearby Milwaukee Tool BLE advertisements, collects GNSS/LTE location data, and publishes to AWS IoT Core over cellular. In doing so it exercises the full Remote Comms contract on actual hardware.
Architecture
The reference implementation is a CompuLab iMX8 running the AWS IoT Greengrass nucleus plus a variety of components. cert-manager establishes the device identity and gates everything else on a cert/ready signal; the other components then scan BLE, collect location, publish asset scans, write shadows, and serve an on-device dashboard. Components talk to each other only over local Greengrass IPC (without leaving the box), and the device reaches AWS over cellular or WiFi.
Data Path
The gateway produces two kinds of data.
Getting Started
Bringing up a reference gateway is three steps you want to stand up a gateway or explore the platform on real hardware. Before this: skim the Overview.
Health Portal
The health portal (the Edge Admin Portal) is an on-device web dashboard served on port 8080. It is your window into a single gateway you want to observe, verify, or debug a running gateway. Before this: skim the Overview.
