The X-CUBE-WATSON software 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-WATSON runs on three platforms.

The B-L475E-IOT01 and 32F413HDISCOVERY boards support Wi-Fi® connectivity with an on-board Inventek module.

The 32F769IDISCOVERY board natively provides an Ethernet interface.

For the three boards, a sample application configures the Wi-Fi® parameters if Wi-Fi® is used, and illustrates the various ways for a device to interact with the IBM Watson IoT™ platform.


  • Ready-to-run firmware example using Wi-Fi® and Ethernet connectivity to support quick evaluation and development of applications on the IBM Watson IoT™ platform
  • Board configuration interface
  • Bidirectional communication examples between the board, acting as a device, and the IBM Watson IoT™ platform
  • Specific features on the B-L475E-IOT01 board such as measurement of humidity, temperature, 3-axis magnetic data, 3D acceleration, 3D gyroscope data, atmospheric pressure and time-of-flight
