The X-CUBE-GCP Expansion Package consists of a set of libraries and application examples for STM32L4 Series, STM32F4 Series, and STM32F7 Series microcontrollers acting as end devices. runs on five platforms. The B-L475E-IOT01A and 32F413HDISCOVERY boards support connectivity with an on-board Inventek module. The 32F769IDISCOVERY board provides a native Ethernet interface. The P-L496G-CELL01 and P-L496G-CELL02 packs include an STM32L496AGI6-based low-power Discovery board equipped with Quectel's UG96 modem (2G/3G) and BG96 modem (LTE Cat M1/NB/2G fallback) respectively for cellular connectivity. For the five platforms, a sample application configures the network connectivity parameters, and illustrates the 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 in order 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 board reports telemetry data such as measurement of humidity, temperature, and atmospheric pressure.
