https://devzone.nordicsemi.com/f/nordic-q-a/83130/adding-custom-uuids-to-nrf-sniffer-wiresharkI am using nRF Sniffer/Wireshark to diagnose some problems with a custom app using 128 bit Service UUIDs as well as well known 16-bit UUIDs. In the screenshot below, you can see that in packet 4988 the sniffer was able to match the 16 bit UUID to theen-USTelligent Community 13Mon, 27 Dec 2021 17:27:02 GMThttps://devzone.nordicsemi.com/thread/345152?ContentTypeID=1Mon, 27 Dec 2021 17:27:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1dabfe3-a7dd-4813-9157-8d517816b104daubsi<p>Thank you for this clarification. I assumed the name of BLE services might have come bundled with the nRF Sniffer plugin but now I&#39;ll ask in the Wireshark support forum!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/345117?ContentTypeID=1Mon, 27 Dec 2021 14:13:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9cafb6be-44a7-43f9-a8b6-45f2515dfe03Hung Bui<p>Hi Markus,&nbsp;</p> <p>I think it&#39;s better a question for Wireshark. I&#39;m not sure if you can add your vendor specific UUID into the Wireshark dissector.&nbsp;<br />We don&#39;t actually define the list of UUID name in Wireshark, we use the BLE protocol analysis built-in in Wireshark so we don&#39;t know how to modify that.&nbsp;</p><div style="clear:both;"></div>
