Currently, until you release new version of S130, I avoid advertising during peripheral connection.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/15528?ContentTypeID=1Mon, 10 Nov 2014 14:20:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:013cbdcd-758b-4962-af63-c288aebf78bdAsbj&#248;rn<p>The current S130 is based on an earlier version of the S110 peripheral stack and it doesn&#39;t support advertising in connected mode. So if you already are connected as a peripheral, you will get the error that you see as you can only have one peripheral connection at the same time.</p> <p>In theory you would be able to do non-connectable advertising while in a peripheral state, but this functionality is not present in the current S130 version. You can still advertise when you have a central connection as this wouldn&#39;t affect the peripheral role.</p><div style="clear:both;"></div>
