Summary of X-CUBE-AZURE – MICROSOFT AZURE SOFTWARE EXPANSION FOR STM32CUBE
The X-CUBE-AZURE expansion package provides libraries and example applications enabling STM32L4, STM32F4, and STM32F7 microcontrollers to act as Azure IoT end devices. It supports four hardware platforms with Wi‑Fi (B-L475E-IOT01A, 32F413HDISCOVERY), Ethernet (32F769IDISCOVERY), and cellular (P-L496G-CELL02 with Quectel BG96) connectivity. Sample apps configure network parameters, demonstrate publishing telemetry and device state to Azure IoT Hub, and handle messages, methods, and twin updates for remote LED control, telemetry interval changes, and remote firmware update triggering.
Parts used in the X-CUBE-AZURE:
- B-L475E-IOT01A board (with Inventek Wi-Fi module)
- 32F413HDISCOVERY board (with Inventek Wi-Fi module)
- 32F769IDISCOVERY board (native Ethernet interface)
- P-L496G-CELL02 pack (STM32L496AGI6 low-power Discovery board)
- Quectel BG96 modem (included on P-L496G-CELL02 for LTE Cat M1/NB/2G)
- STM32L4 Series microcontrollers
- STM32F4 Series microcontrollers
- STM32F7 Series microcontrollers
The X-CUBE-AZURE Expansion Package consists of a set of libraries and application examples for STM32L4 Series, STM32F4 Series, and STM32F7 Series microcontrollers acting as end devices.
X-CUBE-AZURE runs on four platforms. The B-L475E-IOT01A and 32F413HDISCOVERY boards support Wi-Fi® connectivity with an on-board Inventek module. The 32F769IDISCOVERY board provides a native Ethernet interface. The P-L496G-CELL02 pack includes an STM32L496AGI6-based low-power Discovery board equipped with Quectel’s BG96 modem (LTE Cat M1/NB/2G fallback) for cellular connectivity.
For the four platforms, a sample application configures the network connectivity parameters, and illustrates the various ways for a device to interact with Microsoft® Azure® IoT Hub. The application shows how a simple client application connects to the Azure® IoT Hub in order to publish device state and telemetry data, and receive device configuration from the cloud.
The application handles Azure® messages, methods and twin update commands. This allows, from the Azure IoT console, the remote control of the user LED state, the change of the telemetry interval, or the trigger of remote firmware update.
