I am using BLE_Central multilink example to get informaiton from Beacons. I added the below code in the function &quot;ble_evt_handler&quot; from main.c. My beacons are off, but I goten-USTelligent Community 13Tue, 07 Sep 2021 12:19:51 GMThttps://devzone.nordicsemi.com/thread/328386?ContentTypeID=1Tue, 07 Sep 2021 12:19:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cad72b6e-73b3-4235-a4e4-02e68adbdc30Heidi<p>Hi again, you must have modified more of the code because&nbsp;uuid is not defined in the event handler so the code doesn&#39;t run. What SDK version are you on?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/328338?ContentTypeID=1Tue, 07 Sep 2021 09:30:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c4c34107-523b-41c0-89a9-c58e134bd0cfHeidi<p>Hi!</p> <p></p> <p>The BLE Central Multilink sample has a name filter enabled to filter out all advertising packets without the name &quot;Nordic_Blinky&quot;, so I don&#39;t think these packets should be making their way to the application layer at all.&nbsp;</p> <p></p> <p>Have you modified the code at all, a part from the portion you showed in your ticket?</p> <p></p> <p>I will test this a bit here, to see&nbsp;if my understanding is correct.</p> <p></p> <p>I can also suggest setting up a <a href="https://infocenter.nordicsemi.com/topic/ug_sniffer_ble/UG/sniffer_ble/intro.html">BLE sniffer</a>&nbsp;and Wireshark to see all BLE packets, and to check if your Beacons are advertising.</p> <p></p> <p>Best regards,</p> <p>Heidi</p><div style="clear:both;"></div>
