https://devzone.nordicsemi.com/f/nordic-q-a/21072/is-the-advertising-module-removed-from-docsI am programming a beacon, first I had some problems using sd_ble_gap_adv_start() so I changed to ble_advertising_start() . Now I have a problem when compiling: _build/nrf52832_xxaa_main.c.o: In function `advertising_start&#39;: /Users/.../pca10040en-USTelligent Community 13Mon, 03 Apr 2017 23:02:56 GMThttps://devzone.nordicsemi.com/thread/82332?ContentTypeID=1Mon, 03 Apr 2017 23:02:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:32482c6e-923b-4f17-a9f0-7889b418bc03Carlos Villavicencio<p>Kudos for the AdBlock comment.</p> <p>It worked.. somehow. I had this similar problem <a href="https://devzone.nordicsemi.com/question/109587/undefined-reference-to-fs_queued_op_count_get/?answer=114636#post-id-114636">devzone.nordicsemi.com/.../</a> and my solution was to alter the ble_advertising.c file to return false. Maybe something else is missing.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/82331?ContentTypeID=1Mon, 03 Apr 2017 22:01:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3029877b-8290-4413-9836-61b220adb02aDaniel Wang<p>Do you have <code>#define BLE_ADVERTISING_ENABLED 1</code> in sdk_config.h ? You can find it in the docs here: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/group__ble__advertising.html#ga944db395f3667276eb62a8bf3d0583ad">infocenter.nordicsemi.com/.../group__ble__advertising.html</a></p> <p>Turn off e.g. AdBlock if it doesn&#39;t load</p><div style="clear:both;"></div>
