https://devzone.nordicsemi.com/f/nordic-q-a/128019/light-lc-server-with-light-ctl-server-in-nrf52840dkHi, I started from your Bluetooth Mesh NLC: Lightness Controller/Energy Monitor sample and I tried to insert a Light CTL Server model in the project. After a lot of effort now I manage to build and to flash the FW in my nRF52840DK.

I will give you more information on Friday at the latest.&nbsp;</p> <p>Also, please confirm which device you see this BUS FAULT error on, and when exactly in the application it occurs. Is it directly after connecting to the network and sending a light control request or similar, or do you get any successful data transmitted before it crashes?</p> <p>The full log file of when you see this issue would be useful.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
