https://devzone.nordicsemi.com/f/nordic-q-a/84218/nrf52dk-as-snifferHello, I&#39;m trying to use the nRF52DK development kit as a Bluetooth sniffer. after following your &quot;nRF_Sniffer_UG_v2.2.pdf&quot; guide, all I see in Wireshark are advertising messages of the peripheral device. I&#39;m using: Wireshark 3.6.1 sniffer_nrf52dk_nrf52832_4en-USTelligent Community 13Mon, 31 Jan 2022 13:00:59 GMThttps://devzone.nordicsemi.com/thread/350426?ContentTypeID=1Mon, 31 Jan 2022 13:00:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3322127e-59b2-45bd-82eb-4553dcb86330Karl Ylvisaker<p>Great, I am happy to hear that!<br /><br />Please do not hesitate to open another ticket if you encounter any issues or questions in the future.<br /><br />Good luck with your development!<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/350423?ContentTypeID=1Mon, 31 Jan 2022 12:56:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2782da0-2b42-4a0c-bb74-c48bc649ce19oee<p>Hi, after reinstalling wireshark and jlink, and burning&nbsp;sniffer_nrf52dk_nrf52832_7cc811f.hex to the board the sniffer works as expected.<br />thanks</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/350359?ContentTypeID=1Mon, 31 Jan 2022 08:34:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d5b42e78-36a5-4842-b278-4f06894c2781Karl Ylvisaker<p>Hello,</p> [quote user=""]all I see in Wireshark are advertising messages of the peripheral device.[/quote] <p>Could you confirm that you have chosen the device you would like to follow in the wireshark drop-down menu shown in the included image?<br /><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/3364.wiresharkSourceDevice.PNG" /><br />The default here is &quot;all advertising devices&quot; and it means that the sniffer will not follow into any connections.<br /><a href="https://infocenter.nordicsemi.com/topic/ug_sniffer_ble/UG/sniffer_ble/sniffing_actions.html">The User Guide details the most common scenarios here</a>.<br /><br />Furthermore, can you also confirm whether or not the devices use bonding for their connection, so that they might already be bonded to each other? Are you testing this on a windows or OS X machine - which version are you using?<br />Lastly, it would be great if you could include the sniffer trace of any unexpected behavior that you observe, so that I may take a look.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
