  <p>Via both, you are able to communicate with a <a href="https://www.st.com/en/evaluation-tools/stm32-mcu-nucleo.html?querycriteria=productId=LN1847" rel="nofollow noreferrer">microcontroller-board</a>. (I've tested this with a <a href="https://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-idb05a1.html" rel="nofollow noreferrer">BLE-Extansion-board</a>.)</p>
