Those are not the same versions. I found those docs on a google search, so I can see why it&#39;s outdated. At the end I&#39;m coding in a different path and not really using those examples anymore. Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/84071?ContentTypeID=1Tue, 18 Apr 2017 11:10:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f37aa78-619f-48c7-a40a-0632c5249983J&#248;rgen Holmefjord<p>Hi,</p> <p>Which version of the SDK did you download? The documentation you linked is for <a href="https://developer.nordicsemi.com/nRF5_SDK/nRF51_SDK_v8.x.x/">SDK 8.1</a>. The latest version <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/nrf51_setups_serialization.html?cp=4_0_3_1_4">supporting serialization firmware for PCA10028</a> (nRF51 DK) is <a href="https://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v11.x.x/">SDK 11</a>.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/84070?ContentTypeID=1Tue, 18 Apr 2017 11:07:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c546a03-886d-49db-b539-e28e4ed17aa6Ronaldo Pace<p>I&#39;ve found it here <a href="https://developer.nordicsemi.com/nRF5_SDK/nRF51_SDK_v10.x.x/">developer.nordicsemi.com/.../</a> It&#39;s kind of weird that this is not linked in the nRF51 docs.</p><div style="clear:both;"></div>
