https://devzone.nordicsemi.com/f/nordic-q-a/4536/my-code-keeps-crashingI used the ble_app_lbs example as a template, with a PCA10003 eval board (nrf51422 chip). SD 110, Nordic SDK V6.1. Keil uVision 5. I launch my application and my board starts advertising. I can see my board in the Nordic&#39;s Master Control panel, anden-USTelligent Community 13Fri, 21 Nov 2014 16:54:55 GMThttps://devzone.nordicsemi.com/thread/16079?ContentTypeID=1Fri, 21 Nov 2014 16:54:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1875356a-4d86-42b7-bb8c-6dd6e7f052a7c cook<p>Chwi and Stian my board is timing out. Thanks for pointing mein the right direction. The timeout was generating a BLE_GAP_BLE_GAP_EVT_TIMEOUT. The code for this event was putting the board in a low power mode, with a button assigned to wake the board up.</p> <p>Thanks, Clint</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16078?ContentTypeID=1Fri, 21 Nov 2014 15:37:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1dd9e4c5-d5e9-4246-8b83-f9674d627bbfStian R&#248;ed Hafskjold<p>When you call <code>sd_ble_gap_adv_start(&amp;adv_params)</code> in the <code>advertising_start()</code> function. Is the <code>adv_params.timeout</code> set to 0 so it doesn&#39;t timeout?</p> <p>Are you able to set a break point in <code>app_error_handler()</code> at the <code>ble_debug_assert_handler()</code> ? Maybe it returns some useful information</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16077?ContentTypeID=1Thu, 20 Nov 2014 22:01:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d77690d-e988-4549-9673-68100c7149eewlgrd<p>So you have changed the <code>#define APP_ADV_TIMEOUT_IN_SECONDS 180</code> in the example?</p><div style="clear:both;"></div>
