I set up a ap router which has dhcpv6 server and build "test.console-BCM943362WCD4-ThreadX-NetX_Duo-SDIO download run" to my EVB(BCM943362WCD4).
I can only get IPv4 address from status and also check ap's dhcpv6 table.
There is no global IPv6 address in EVB.
The latest release 3.5.2 has IPv6 implemented. Kindly verify with the latest WICED SDK release.
