Hi everyone,
I have a project that is running LwIP V2.1.2. The stack is LwIP on top of BG96 cellular modem.
It works fine for IPV4, but when I enable IPV6, I only get IPV6 link local address, and cannot get real IPV6 address, therefore, I cannot connect to my server.
The LwIP comes from ST cellular expansion package.
I enable the log, and it got local and remote LL address, but after that never got any real address, and cannot connect to my server.
thanks a lot for any hints or suggestions.
thanks
Ivan
