IPV6 support for ESP32

[ESP_Sprite]

It's on our list of things to tackle, but we do not know yet in which version an implementation will get released.

Hi,

Ok. Then with which ESP32 SDK I have to go to check IPV6 support for my application development? Still, I will also check each and every logs of commit in parallel to find out changes for IPV6 related support.

Hi Espressif System Developer Team,

As per commit logs of current ESP32 IDF RTOS SDK, It seems that we can not use DHCPV6 support into existing ESP32-IDF V2.1 or Mater ESP32 IDF SDK. Do you have any idea like in which ESP32 SDK DHCPV6 support will be added?

We have checked IPV6 support in detailed specific to LWIP source point and found that it supports only IPv6 SLAAC for IPV6 feature. We have also checked APIs and found tcpip_adapter_create_ip6_linklocal() and tcpip_adapter_get_ip6_linklocal() to create IPV6 supported link but which is local link means only ESP32 devices can communicate with each other instead of external network.

We could not found any more APIs into LWIP source as well other IPV6 supported source to create external IPV6 supported Link.

Would you please check that stuff internally with the help of your SDK Engineer and provide any information/suggestions for that.

I will be waiting for your reply or any positive feedback on this as soon as possible.

Slaac should work automatically to get router advertisement, get new IP in event handler, and whether the IP is reachable from the internet depends on router and firewall settings.

Hi WiFive,
As it configures link local address, is it possible to connect esp32 with external link server with IPv6 socket.? I think it requires to be in the same networks to get connected. I connected two esp32 through IPv6 socket links but still confuse about connecting esp32 with external server through ipv6 sockets as link local address only works within same networks or requires direct connection(link) between devices. Is it so or I understood it wrong way.?

Thanks.

Slaac will get you another ip6 address if you have a router supporting it. That ip6 will not be link local.

Hi Espressif Systems Developer,

When we will get ESP32 IDF 3.0 SDK? Is there any plan to release within one or two week?
