The project is showcasing a simple way of using the the BleuIO Dongle to turn on and off a light bulb that is connected to the STM32 Nucleo-144 via a 5V Relay.
You will need two dongles, one connected to the Nucleo board and one connected to a computer, running the web script.
We have used a STM32 Nucleo-144 development board with STM32H743ZI MCU (STM32H743ZI micro mbed-Enabled Development Nucleo-144 series ARM® Cortex®-M7 MCU 32-Bit Embedded Evaluation Board) for this example.
