However when I do this FreeRTOS stops working normally. Any thoughts? Is there an alternative way to put theen-USTelligent Community 13Fri, 06 Apr 2018 12:57:30 GMThttps://devzone.nordicsemi.com/thread/127226?ContentTypeID=1Fri, 06 Apr 2018 12:57:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:67d44a7b-6905-44fd-bc30-2005a37abc92Sumanth Murali<p>Hi, I&#39;m saving the same issue.

It wouldn&#39;t do much as long as you don&#39;t use it, i.e. don&#39;t advertise, scan and so on.</p><div style="clear:both;"></div>
