My goal is to create a Smart Home ZigBee hub which could control smart switches compliant with the technology.

You can see which examples are supported on which boards&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/zigbee_only_examples.html">here</a>.</p> <p>One of the reasons the light bulb example is not supported is because four different buttons are used in the example, while the Dongle only has one user configurable button. Thus, the example is not compatible with the dongle without changing the code so that you only use one button. If you want to use the light switch on your dongle, you&nbsp;must&nbsp;figure out what you want your button to do, and then you must change the code accordingly, also removing the other buttons from the code. You should only use&nbsp;BSP_BOARD_BUTTON_0.</p> <p>You can find how to adapt nRF5 SDK projects for the dongle in our&nbsp;<a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial">nRF52840 Dongle Programming Tutorial</a>.</p> <p>We recommend using a DK and not the dongle when developing, as it offers more features than the dongle, and&nbsp;is better suited for development.</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>
