Hi all,
Would like to update, my device can now change ip address during runtime
thanks to Ivan's suggestion. Here is my steps (roughly):
1. netif_set_addr() //to change ip address
2. netconn_close(old_netconn)
3. netconn_delete(old_netconn)
4. new_netconn = netconn_new()
5. ip_set_option([new_netconn]->pcb.ip_pcb, SOF_REUSEADDR)
6. netconn_bind(new_netconn, NULL, your_socket)
7. netconn_listen(new_netconn)
