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
