 We are using the nrf connect Android app in order to scan and connect to ble peripherals. 
 The scan procedure is executed perfectly as we can identify and connect to all ble peripherals, one by one. 
 Also, we can still connect to a second one</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 30 Sep 2019 13:54:55 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/52741/connect-on-3-or-more-peripherals" /><item><title>RE: Connect on 3 or more peripherals</title><link>https://devzone.nordicsemi.com/thread/212634?ContentTypeID=1</link><pubDate>Mon, 30 Sep 2019 13:54:55 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:e4eedc4e-c545-48f5-a23e-b1f98631c716</guid><dc:creator>awneil</dc:creator><description>[quote userid="79896" url="~/f/nordic-q-a/52741/connect-on-3-or-more-peripherals/212626"]i used a different smartphone and it works[/quote]
&lt;p&gt;Yes - different phones will have different capabilities.&lt;/p&gt;
&lt;p&gt;It shows that it&amp;#39;s not a fundamental limitation of nRF Connect.&lt;/p&gt;
&lt;p&gt;If that&amp;#39;s resolved your issue, please verify the answer.&lt;/p&gt;

&lt;p&gt;If you want to investigate further then, as suggested, the nRF Logs are probably the place to start ...&lt;/p&gt;

&lt;p&gt;I shouldn&amp;#39;t mention that &amp;quot;&lt;span&gt;a central device can handle up to 7 peripherals&amp;nbsp;&lt;/span&gt;&lt;span&gt;simioutanesly&lt;/span&gt;&amp;quot; because i am not able to give a reference on that. Despite that, i used a different smartphone and it works. The only difference between the devices on device information menu is that the second smartphone has &amp;quot;Multiple advertisement supported&amp;quot; as YES, but i dont believe that it is the issue as this option refers to peripherals.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Connect on 3 or more peripherals</title><link>https://devzone.nordicsemi.com/thread/212605?ContentTypeID=1</link><pubDate>Mon, 30 Sep 2019 12:48:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:29760b3d-9f49-48d0-8335-839998d64e70</guid><dc:creator>awneil</dc:creator><description>&lt;p&gt;Have you looked at the nRF logs to see what&amp;#39;s happening when it fails?&lt;/p&gt;
