  • The X-CUBE-GCP Expansion Package provides the porting of the Google Cloud™ IoT Device SDK for STM32L4 Series microcontroller acting as end device. X-CUBE-GCP runs on the B-L475E-IOT01A Discovery kit using Wi-Fi® connectivity with an on-board Inventek module. For this platform, a sample application configures the network connectivity parameters, and illustrate various ways for a device to interact with the cloud. The application shows how a simple client application can connect to the IoT Core service of Google Cloud Platform™ to publish device state and telemetry data, and receive device configuration from the cloud. Device authentication through JWT (Json Web Token), TLS encryption, and authentication are supported. The B-L475E-IOT01A board reports telemetry data such as measurement of humidity, temperature, and atmospheric pressure.

    Key Features

    • Quick evaluation and development of IoT Core service for the Google Cloud Platform™
