Here&#39;s an example of scanning and finding 11 APs within my range:</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1676640341194v1.png" alt=" " /></p> <p>&nbsp;</p> <p>You can use the &quot;shell&quot; sample to actively scan.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
