From multiple Q&amp;As on this forum it looks like Nordic guys recommend to set short scan interval (even &lt;10ms) if you want to use 100% duty cycle (interval == window) and do some other actions on the background (like concurrent advertising) because then Soft Device can prioritize the tasks better.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/87720?ContentTypeID=1Sun, 28 May 2017 08:37:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:342de881-fc6d-4f74-b303-60b37ccda669All4here<p>i edit the post.sorry before it was bad written.
