 Is it possible to increase the accuracy of the advertise interval? Im attaching an oscilloscope screenshot showing the S110 device advertising with a 20ms interval and running on the internal LFCLK. Im toggling a pin on a radio notification</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 22 May 2014 12:11:47 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/2559/accuracy-ble-advertising" /><item><title>RE: Accuracy BLE: advertising</title><link>https://devzone.nordicsemi.com/thread/10182?ContentTypeID=1</link><pubDate>Thu, 22 May 2014 12:11:47 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:66533c0a-8074-4d35-bf24-93a0c9fc94f7</guid><dc:creator>pascal defesche</dc:creator><description>&lt;p&gt;Thanks for your explanation!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Accuracy BLE: advertising</title><link>https://devzone.nordicsemi.com/thread/10181?ContentTypeID=1</link><pubDate>Thu, 22 May 2014 10:28:12 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ab1f1377-96a4-4ef7-8f5a-da584b6e0106</guid><dc:creator>Stefan Birnir Sverrisson</dc:creator><description>&lt;p&gt;Hi Pascal&lt;/p&gt;
&lt;p&gt;This is actually a part of the BLE protocol. You set the advertising interval to 20 milliseconds, the softdevice will automatically add few milliseconds to the advertising interval. The number of added milliseconds is randomly picked. The purpose is to prevent that a scanning device with the same  scanning interval will never discover the peripheral device.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
