If so, this course is based on nRF Connect SDK, not nRF5 SDK. The requirement to take the Bluetooth Low Energy Fundamentals course is to go through <a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/lessons/lesson-1-nrf-connect-sdk-introduction/">Lesson 1</a> of the nRF Connect SDK Fundamentals course. That lesson covers tools and SDK installation, and you can choose which version of nRF Connect SDK you want to work with.&nbsp;It is recommended that you go through the whole course as well, but not required.</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
