Hi all, I have come across an issue related to DHCP and link status. The device does not restart the dhcp negotiation whenever the link goes down and up automatically. Note that I have an interrupt callback for PHY link up/down. How should the dhcp be handled when the link up/down event occurs? I have seen many posts regarding the same, but i just wanted to make sure that we are doing this in the correct way. Please help.
Make sure you get from the PHY interrupt into tcpip_thread and call dhcp_network_changed() from there. That should be all. Regards, Simon
I just read that dhcp_network_changed() shall be used in case the lease time has not expired and dhcp_start shall be used if the dhcp server changes/reboots. Please correct me if i am wrong. regards, Vinu -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list address@hidden https://lists.nongnu.org/mailman/listinfo/lwip-users
