&lt;p&gt;Thanks for your reply, I&amp;#39;m currently using Keil. I unfortunately cannot share the code. So if I get it correctly, your suggestion is to try one of the SDK samples? I will do that next week and will let you know how I go (holidays at the moment). Thanks!&lt;/p&gt;

&lt;p&gt;I suspect you were using wrong device definition and/or start up code. Could you&amp;nbsp;let us know which IDE you are using ? And maybe post your code/project here ?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;We suggest to use Keil or Segger Embedded Studio.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Could you try and test a nRF5 SDK ? The current SDK is SDK v15 (SDK v11 if you are using nRF51).&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you want to test with bare metal code, you can have a look &lt;a href="https://github.com/andenore/NordicSnippets"&gt;here&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
