https://devzone.nordicsemi.com/f/nordic-q-a/12059/nrf51-dk-crash-after-5minsI&#39;m running a BLE Free rtos example code with the UART service example code. I noticed that after 3-5 minutues of advertising the BLE service it stop advertising...I&#39;m guessing a crash. Any ideas why ? How would one debug this kind of issue. thanksen-USTelligent Community 13Mon, 22 Feb 2016 22:16:13 GMThttps://devzone.nordicsemi.com/thread/45661?ContentTypeID=1Mon, 22 Feb 2016 22:16:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dafc28d5-7a9d-45c7-9592-87ab485e632aypearson<p>That&#39;s likely it. Thanks</p> <p>I&#39;ll test it and report back.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45660?ContentTypeID=1Mon, 22 Feb 2016 18:32:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:039fabe4-a341-4569-8abe-bae77fe8e2f5Keton<p>Most SDK examples stop advertising after some time. This is due to usage of a advertising manager module <code>ble_advertising.h</code>. Google suggests that you are using example code similar to <a href="https://github.com/monpetit/nrf52-ble-hrs-freertos-demo/blob/master/main.c">this</a>. Look for <code>on_adv_evt</code> function, specifically for <code>BLE_ADV_EVT_IDLE</code> event. Change <code>sleep_mode_enter();</code> to <code>advertising_start();</code>. As for debugging use nrf_log.h and either UART or RTT.</p><div style="clear:both;"></div>
