Instead, you should ping the Nordic device using the global IP address which starts with the global IPv6 prefix you assigned your BT0 network. If you haven&#39;t done that you can follow this guide: <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.iotsdk.v0.9.0/iot_sdk_user_guides_radvd.html">infocenter.nordicsemi.com/.../iot_sdk_user_guides_radvd.html</a></p><div style="clear:both;"></div>
