Hi, @MrShen
Sorry for the inconvenience to you.
I received our internal team's feedback that due to recent change in ACH Matter Zigbee Bridge, we need to update UG10185.
Can you please have a try with below command and let me know whether it works for you?
git clone -b rw612_with_external_transceiver https://github.com/nxp-appcodehub/dm-matter-zigbee-bridge-rw612.git
I tried on my local side, I can download it.
By the way, for your convenience, we have have an update README in below link:
https://github.com/nxp-appcodehub/dm-matter-zigbee-bridge-rw612/blob/rw612_with_external_transceiver...
Please let me know whether have any other concerns on this case, other wise, please do not hesitate to mark my answer as a solution, so that we can close this case.
Thanks!
Best regards,
Christine.
