&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/members/kme"&gt;Kenneth&lt;/a&gt;&amp;nbsp;is currently out-of-office (summer vacation season here in Norway.)&lt;/p&gt;
&lt;p&gt;From what I understand the functionality that you ask for does not fit with the way this event currently works. As is, you get a count describing how many packets are sent. In order to get more information about what packets, we would either need a variable size data structure, or send an event for each and every packet sent.&lt;/p&gt;
&lt;p&gt;The purpose of the event is currently to let you know the size of the tx queue, so that you know when you can queue more packets. For what purpose would you like to know what particular characteristic has been notified?&lt;/p&gt;
&lt;p&gt;Notifications should only fail if the connection is lost before the notification has been successfully sent, after which you should get a disconnect event.&lt;/p&gt;
&lt;p&gt;Regards,&lt;br /&gt;Terje&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: BLE slave notification success callback</title><link>https://devzone.nordicsemi.com/thread/198516?ContentTypeID=1</link><pubDate>Mon, 15 Jul 2019 14:01:55 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:8af688e5-1881-4f8d-bce2-4c3a2b3abb76</guid><dc:creator>chandan</dc:creator><description>&lt;p&gt;Can we expect it add on future SDKs?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: BLE slave notification success callback</title><link>https://devzone.nordicsemi.com/thread/198139?ContentTypeID=1</link><pubDate>Fri, 12 Jul 2019 11:32:16 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:8ef56779-b7ec-4418-9661-d15b80ce028f</guid><dc:creator>Kenneth</dc:creator><description>[quote user=""]I want to know if there is any feature to know if notification from particular characteristic has successfully sent / failed[/quote]
