&lt;p&gt;The pack system was introduced together with SDK v7, so you will have to use the &amp;quot;old style&amp;quot; SDK.
SDK V4 is now available &lt;a href="http://developer.nordicsemi.com/nRF51_SDK/"&gt;here&lt;/a&gt;. You can either download an .msi-install file or a .zip file. The install file is pretty self-explanatory, but you can also just unzip the .zip file to any folder you like and open the examples.&lt;/p&gt;
&lt;p&gt;You mixed up the SDK and SD versions, by the way. Rev 1 is compatible with SD 5.2.1 and SDK 4.4.2.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
