Unable to Decode Matter IM Traffic in Wireshark using nRF52840-DK as Thread Snifferhttps://devzone.nordicsemi.com/f/nordic-q-a/126159/unable-to-decode-matter-im-traffic-in-wireshark-using-nrf52840-dk-as-thread-snifferHi, I have developed a Matter-over-Thread light bulb using the Silicon Labs EFR32MG24 platform, with CHIP_CONFIG_SECURITY_TEST_MODE = 1 enabled. In parallel, I have set up an OpenThread Border Router (OTBR) on a Raspberry Pi and retrieved the Threaden-USTelligent Community 13Wed, 25 Feb 2026 11:20:09 GMTRE: Unable to Decode Matter IM Traffic in Wireshark using nRF52840-DK as Thread Snifferhttps://devzone.nordicsemi.com/thread/562021?ContentTypeID=1Wed, 25 Feb 2026 11:20:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c506fdb-4102-4eee-b852-77bb61a8792dMaria Gilje<p>Hello,&nbsp;</p> <p>My apologies for the delay. I have confirmed that our nRF Sniffer for 802.15.4 does not support Matter. If you are able to capture and decrypt any packets, this is not an intended feature and we have no guarantee that capturing and decrypting Matter packets works with the nRF Sniffer for 802.15.4.&nbsp;</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>RE: Unable to Decode Matter IM Traffic in Wireshark using nRF52840-DK as Thread Snifferhttps://devzone.nordicsemi.com/thread/557647?ContentTypeID=1Mon, 29 Dec 2025 10:27:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56ac6c52-5bfd-4a26-a710-0b6ae26e464aMaria Gilje<p>I see.

This will help us to find out where the issue is. If it is not reproducible with our hardware, you would need to go to Matter support with this issue.&nbsp;</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>RE: Unable to Decode Matter IM Traffic in Wireshark using nRF52840-DK as Thread Snifferhttps://devzone.nordicsemi.com/thread/557283?ContentTypeID=1Thu, 18 Dec 2025 05:48:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:42e879cd-113a-4a2d-bc39-03757559e35fPavan Kumar C<p>Thank You So Much, it would be of great help if u tell how to decrypt wireshark packets using nordic thread sniffer</p><div style="clear:both;"></div>RE: Unable to Decode Matter IM Traffic in Wireshark using nRF52840-DK as Thread Snifferhttps://devzone.nordicsemi.com/thread/557237?ContentTypeID=1Wed, 17 Dec 2025 14:30:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ca9115dc-45e1-495a-8a9c-fd26ee4ca9feMaria Gilje<p>Hello,&nbsp;</p> <p>I want to start out by letting you know that since Nordic does not develop nor maintain the matter-dissector plugin, there is a possibility that what we can offer in terms of support for this is quite limited. I will investigate if there is something we can do though. Thank you for your patience.&nbsp;</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
