https://devzone.nordicsemi.com/f/nordic-q-a/15453/wireshark-manufacturer-dataI&#39;m starting to use Wireshark a little more and sometimes it is not displaying all of a device&#39;s manufacturer data. For example on some devices it is not displaying the manufacturer company identifier nor the custom payload. I see this data using theen-USTelligent Community 13Tue, 02 Aug 2016 13:12:17 GMThttps://devzone.nordicsemi.com/thread/59011?ContentTypeID=1Tue, 02 Aug 2016 13:12:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4905b212-7e6f-4e1e-bc03-109e6d639912RichieJH<p>Indeed. So it looks like nRF Connect/MCP take both the advertisement and the scan response and cojoin them as one &quot;advertisement&quot;.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/59009?ContentTypeID=1Tue, 02 Aug 2016 12:30:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3c40915d-8d2d-4ebf-bf1f-fecf72fc0ec8Hung Bui<p>@RichieJH: I agree with what Jon said, as you can find the data size in the screenshot with Master Control Panel app is much bigger than the max size of an advertising packet which is 31 bytes. Most likely you included the Manufacturer data in the scan response packet.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/59010?ContentTypeID=1Tue, 02 Aug 2016 09:10:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a8efdd8-b9b0-4c37-bfce-2784266e69a4jon<p>Have you tried running the sniffer while the Android App is scanning? I suspect you will see a SCAN_REQUEST packet from the phone, and a SCAN_RESPONSE from the device with the missing info. Since wireshark is just passively listening, it cannot request this additional info by itself.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/59008?ContentTypeID=1Tue, 02 Aug 2016 06:08:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:26832eca-d68e-4d4a-b45e-dfcde5515bd1RichieJH<p>Here are screen shots of both the Wireshark and MCP representation of the data (above in original question). It appears that Wireshark is not showing all of it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/59007?ContentTypeID=1Mon, 01 Aug 2016 11:44:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fc7661fe-4f79-4a14-a2c0-815cf64a5947Hung Bui<p>@Richie: Could you update a screenshot and maybe the sniffer trace file ?</p><div style="clear:both;"></div>
