The project is showcasing a simple way of using the the BleuIO Dongle to advertise data that the STM32 reads from a sensor which is connected to the STM32 Nucleo-144. Requirments : A BleuIO dongle (https://www.bleuio.com/) A SHT85 sensor (https://sensirion.com/products/catalog/SHT85/) A board with a STM32 Microcontroller with a USB port. (A Nucleo-144 development board: NUCLEO-H743ZI2, was used developing this example. (https://www.st.com/en/evaluation-tools/nucleo-h743zi.html) To connect the dongle to the Nucleo board we used a “USB A to Micro USB B”-cable with a USB A female-to-female adapter.)
