&lt;p&gt;If the Bluetooth get disconnected and your device needed to be reset, it&amp;#39;s more likely it got asserted. Please follow the debug guide &lt;a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/#60126"&gt;here&lt;/a&gt;. You need to find where it got asserted and because of which error code.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;How do you send your data to Bluetooth from UART ? Do you have a check if the Bluetooth buffer is overflow and retry it after more packets have been sent ?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Note that you will receive&amp;nbsp;BLE_GATTS_EVT_HVN_TX_COMPLETE event when there is notification(s) sent over Bluetooth&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
