Supported Features

Networking Features

• Bi-directional IPv6 Connectivity: The devices on the backbone link (typically Wi-Fi) and the Thread network can reach each other.
• Service Discovery Delegate: The nodes on the Thread network can find the mDNS services on the backbone link.
• Service Registration Server: The nodes on the Thread network can register services to the border router for devices on the backbone link to discover.
• Multicast Forwarding: The devices joining the same multicast group on the backbone link and the Thread network can be reached with one single multicast.
• NAT64: The devices can access the IPv4 Internet via the border router.

Production Features

• RCP Update: The built border router image will contain an updatable RCP image and can automatically update the RCP on version mismatch or RCP failure.
• Web GUI: The border router will enable a web server and provide some practical functions including Thread network discovery, network formation and status query.
