https://devzone.nordicsemi.com/f/nordic-q-a/106937/notification-sent-acknowledgementHi, SDK 17.1.0 How can the Application make sure that the notification message has been sent ? Please note that, I am not asking about ack from the client as I know that there will be no ack for notification. For example: err_code = sd_ble_gatts_value_seten-USTelligent Community 13Thu, 28 Dec 2023 14:17:10 GMThttps://devzone.nordicsemi.com/thread/461981?ContentTypeID=1Thu, 28 Dec 2023 14:17:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a90ccb66-782d-4351-9208-3d3c672bbc2covrebekk<p>You welcome <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile">&#x1f642;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/461875?ContentTypeID=1Wed, 27 Dec 2023 22:22:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7df22994-4547-4df3-8131-2b51eae9dcb8DanisXZ<p>Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/461787?ContentTypeID=1Wed, 27 Dec 2023 12:08:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc28960c-02df-45a5-81fb-4bfea2ce1eb2ovrebekk<p>Hi&nbsp;</p> <p>The stack will return the&nbsp;BLE_GATTS_EVT_HVN_TX_COMPLETE event once a notification has been sent successfully. In case multiple notifications are queued at the same time you might get a single event representing multiple notifications, but if you&#39;re only sending a single packet this should not be relevant.&nbsp;&nbsp;</p> <p>Ideally you should disconnect the link before entering system off,&nbsp;rather than just drop the link in the middle of a connection, to avoid the connected peer wasting time trying to keep the link alive.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
