 Background: 
 I&amp;#39;m working on a project where I try to synchronize a wireless sensor network, where the sensors are nrf52 devices. I have gotten to a point where the mean accuracy error lies around 2ms in between the nodes.

By the way, the relevant files for you inside the examples are the files ending in &amp;quot;timeslot&amp;quot; (f. ex. scanner_beacon_timeslot). I see now that the examples also implement scanning / advertising with the softdevice. This is because this is now possible while in a connection, but it was not when the example was written the first time.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: scan time per channel</title><link>https://devzone.nordicsemi.com/thread/54355?ContentTypeID=1</link><pubDate>Thu, 02 Jun 2016 15:50:00 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:89f86824-5834-4dca-b10d-657c69abed15</guid><dc:creator>Kristoffer Hilmersson</dc:creator><description>&lt;p&gt;I see, thank you! And the advertisment time on each channel depends on the advertisement data length?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: scan time per channel</title><link>https://devzone.nordicsemi.com/thread/54353?ContentTypeID=1</link><pubDate>Thu, 02 Jun 2016 14:14:47 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:2693ea0d-9766-4f5e-902a-f20eedc7c1df</guid><dc:creator>Anders Strand</dc:creator><description>&lt;p&gt;Hello.&lt;/p&gt;
&lt;p&gt;You will scan on each channel as long as the scan window is set. See the scanning section of the &lt;a href="https://devzone.nordicsemi.com/tutorials/21/"&gt;ble central tutorial.&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;You might be interested in using the &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.sds/dita/softdevices/s130/concurrent_multiprotocol_tsl_api/concurrent_multiprotocol_tsl_api.html"&gt;timeslot&lt;/a&gt; API, where you can control the radio manually. Then you can broadcast advertisements and scan on certain channels. Check out the timeslot &lt;a href="https://devzone.nordicsemi.com/tutorials/16/"&gt;tutorial&lt;/a&gt;, and the &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/ble_sdk_app_multi_activity.html?cp=5_0_0_4_2_2_25"&gt;multiactivity examples.&lt;/a&gt;
The multiactivity examples show how to both advertise and scan inside timeslots.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
