Hi,

I'm using LwIP v2.2.0.
I need to run DHCP and AutoIP on our device. I've configured LwIP
correctly, I think. DHCP and AutoIP work well, but AutoIP feature
works only once.
If the device has not received a configuration from a DHCP server
and has sent "DHCP Discover" more than the defined number
of times, then AutoIP starts.
Later, when the device receives an offer from the DHCP server,
it rebinds its address. However, if the DHCP server becomes
unavailable again and the device's lease time expires, AutoIP feature
doesn't work. LwIP attempts to start AutoIP every time the tries
counter exceeds "LWIP_DHCP_AUTOIP_COOP_TRIES" but AutoIP
remains in "AUTOIP_STATE_BOUND," and the device can't obtain
a 169.254.xxx.xxx address.

Am I doing something in the wrong way? Maybe it is a bug in LwIP?

Bartek
