I have tested this on my mac &amp; I receive the exact same problem that you have. Did you remember to put the cloned folder in this path:&nbsp;<span>$HOME/.nrfconnect-apps/local/? Also, you will need to install nRF Connect like shown. Then, if you have done everything correctly, which I suspect you have, you should see a local Bluetooth Low Energy application like shown below when you open nRF Connect v2.5.0</span></p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-91ac4075c5b94ec0a2beb6e2fec46283/Screenshot-2018_2D00_10_2D00_19-at-15.43.44.png" alt=" " /></p> <p>When you launch it, the app should work successfully.</p> <p>Kind Regards,</p> <p>Bjørn</p><div style="clear:both;"></div>
