https://devzone.nordicsemi.com/f/nordic-q-a/38131/examples-using-sdk-15Hi, Currently I&#39;m upgrading our code base to SDK 15. At https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/migration.html?cp=4_0_1_1_9 there are some directions written down. Note, by the way that there is no migration guideen-USTelligent Community 13Tue, 04 Sep 2018 13:06:05 GMThttps://devzone.nordicsemi.com/thread/147185?ContentTypeID=1Tue, 04 Sep 2018 13:06:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d39a624-471f-4aa8-ab21-cbe142e4f661Anne van Rossum<p>Super, that pointed me in the right direction!!

Especially so when using the SoftDevice directly (as you do with advertising.) You should find it in &lt;sdk folder&gt;/components/softdevice/&lt;softdevice name&gt;/doc/.</p> <p>My guess is that the lifetime of the ble_gap_adv_data_t structure is too short. See the Detailed Description section of the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.api.v6.1.0%2Fstructble__gap__adv__data__t.html">ble_gap_adv_data_t Struct Reference</a>.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
