IPv6 support of FreeRTOS/LwIP in WICED SDK 6.6.1.1

[HyKi_4229111]

Hello,

I'd like to know whether WICED SDK supports IPv6 as the same question was asked in other message,  https://community.infineon.com/t5/Wi-Fi-Combo/IPv6-support-in-wiced-sdk/m-p/288568, but never replied.

My app is using FreeRTOS/LwIP with IPV4+IPV6 configured and has no problem on IPv4 communication. However, the app never receives any of IPv6 packets from the network. I wonder this is because my app fails to setup IPv6 (problem somewhere on create socket, bind and/or receive) or the network chip (4343W) does not support IPv6. When I try to send an IPv6 multicast packet, then it goes to the network and arrives at the other device. But same sequence with different direction, that is, the other device sends a packet but my app doesn't receive. More specifically, the function  host_network_process_ethernet_data() in wwd_network.c has never called for IPv6 packet arrival. A ping6 also fails to get answer from my device.

Please let me know if it supports IPv6, so I can go a good direction.

Regards.

Hi,

Ping for ipv6 is not implemented in WICED. You can check the following snapshot.

Thanks

I know ping6 is not going out to the network, but does it not answer ping6 from other device, either?

The most important question for me is if WICED supports IPv6 communication. Specifically, network chip (4343W) transfer IPv6 packets to WWD and network?

Thanks.
