As mentioned on the mailing list, lwIP should inform the application about a successful DHCP reboot even if the assigned address did not change. Currently, there does not appear to be a consistent way to get a notification when the link becomes ready for TCP or UDP, i.e. when a valid IP configuration was (re-)acquired. This would be useful if the application needs to use TCP/UDP as sson as possible, including after a reconnect. Therefore, some kind of callback for "IP ready" would be useful. |
