&lt;p&gt;From the link you suggested, the memory allocated for app timer was indeed  the culprit. My own code had left the allocation at its default, which used up too much RAM. After I decreased the allocation, and compiled using 0x2000 IRAM size, I successfully got master control panel to see my device!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: custom service, trouble compiling and running.</title><link>https://devzone.nordicsemi.com/thread/3061?ContentTypeID=1</link><pubDate>Fri, 04 Oct 2013 12:31:31 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b438c6ed-82e3-433b-9f41-5df919dca888</guid><dc:creator>Ole Morten</dc:creator><description>&lt;p&gt;Just increasing the RAM size in your project file is a little optimistic, since that (unfortunately) won&amp;#39;t increase the physical amount of RAM available. ;)&lt;/p&gt;
&lt;p&gt;The solution is therefore to put this back to 0x2000, and instead reduce RAM usage in other ways. The .map file generated by the linker is a great help to know which parts of your code consumes memory, and it can also be useful to take a look at &lt;a href="https://devzone.nordicsemi.com/index.php/putting-my-app-on-a-ram-memory-diet"&gt;this question&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
