https://devzone.nordicsemi.com/f/nordic-q-a/102758/listening-to-the-broadcaster-nrf52dk-nrf-sdk-connect-2-2-0Hi, I ran basic broadcaster sample from zephyr, and also I ran the observer sample which observed surrounded devices. I flashed broadcaster sample to one nrf52dk and an observer sample to another nrf52dk, I want observer to listen the broadcaster&#39;s advertisingen-USTelligent Community 13Fri, 11 Aug 2023 12:59:36 GMThttps://devzone.nordicsemi.com/thread/440969?ContentTypeID=1Fri, 11 Aug 2023 12:59:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:13a3e61a-17e1-4890-a71c-1c789922203bEdvin<p>Hello,</p> <p>I suggest you check out the sample found in ncs\zephyr\samples\bluetooth\central. It is a very simple sample that will start scanning, and whenever it picks up an advertisement packet, it will trigger the device_found() callback in main.c. The advertisement packet in raw format is found in the &quot;struct net_buf_sample *ad&quot; parameter. If you are interested in how to parse these kind of raw packets, I suggest you take a look at our <a href="https://academy.nordicsemi.com/topic/advertisement-packet/">Bluetooth Low Energy course on DevAcademy</a>.</p> <p></p> <p>To find the values for the different &quot;Advertisement Data Structures&quot;, you can look them up in gap.h, located in ncs\zephyr\include\zephyr\bluetooth\gap.h</p> <p></p> <p>Note that this sample application will connect to all devices that has an RSSI &gt; -70 dBm. You probably want to comment out this if you just want to monitor advertisement packets.</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
