https://www.eevblog.com/forum/microcontrollers/any-experts-on-lwip-and-the-netconn-api-(not-looking-for-free-can-pay)/msg4342318/#msg4342318 It's a pity this list is practically dead.

Well nobody is going to reply to that question, too :) _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
