This will only work on one link, for example the bt0 link, or the et0 link. To communicate between links you need to use a global prefix, to make a global IPv6 address. RADVD distributes these global prefixes.&lt;/p&gt;
&lt;p&gt;Please have a look at &lt;a href="https://devzone.nordicsemi.com/question/41628/iot-sdkpc-cannot-ping-pca10028/"&gt;this&lt;/a&gt; question for how to set it up.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: can't connect the device running coap server example</title><link>https://devzone.nordicsemi.com/thread/32127?ContentTypeID=1</link><pubDate>Tue, 18 Aug 2015 09:16:10 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:db5afff3-086a-4166-bc47-d1bb7ebde110</guid><dc:creator>horiebin</dc:creator><description>&lt;p&gt;I ping on my pc (windows 7)  &lt;code&gt;ping -6 fe80::24b:e3ff:fec6:1cc1&lt;/code&gt; and it return “Destination host unreachable”.
But ping on rpi is ok    &lt;code&gt;ping6 -I fe80::24b:e3ff:fec6:1cc1&lt;/code&gt;&lt;/p&gt;
&lt;p&gt;In the python script I change the SERVER_ADDR&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;SERVER_ADDR = &amp;#39;FE80::24B:E3FF:FEC6:1CC1&amp;#39;
