Using RTC along with ble soft device and app timerhttps://devzone.nordicsemi.com/f/nordic-q-a/51091/using-rtc-along-with-ble-soft-device-and-app-timerWe are using nRF52832 in our design. We want to collect sensor information along with time stamp. So I took nRF calendar application and tested the same. It was working fine. Then I added app timer along with BLE pheripheral (uart) application.

I wasn&#39;t able to find one in the calendar example, so I&#39;m assuming it is somewhere in your initial application.&nbsp;Does this occur while you&#39;re advertising? In that case, I&#39;m guessing it&#39;s the&nbsp;<strong></strong>APP_ADV_DURATION that triggers. You can set this to 0 in the main.c file in order to advertise indefinitely.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
