connectedhomeip (CHIP) application

[QuentinCaldeira-eaton]

Hi ! I think it's not the right place, but I can't have any support on connectedhomeip side.
I'm working on making the Zephyr standalone platform usable for anybody, because for now only nRF, telink and nxp use it. The purpose is to allow any compatible board in terms of FLASH, connectivity, etc. to build connectedhomeip application from the zephyr sdk directly.
The standalone platform is working, and anybody can build now, but I think some things are missing. For my test, I use a nucleo h563zi with Ethernet, and my purpose is to make a commission over Ethernet (on network), to have a Light device.
I don't know why, but it seems that mDNS isn't working (I guess). When I boot the card, it appears with the address "::" and the protocol ICMPv6 in Wireshark. I think there is no IP attribution. My application says that "mDNS service published: _matterc._udp", but there are no traces in Wireshark. Also, I can't commission the device in CHIP-TOOL.
My knowledge about networking is quite limited and seems to be the issue. If someone have any idea ? I can provide my application, and the .config, because I think prj.conf only isn't relevant, application sources other Kconfig.
