[lwip-users] DHCP restart

[Carr, Anthony]

Hi,

 

I am a new user of lwip and am looking for some assistance.

I am working on a product that can be configured to use DHCP or fixed IP address.

The system works fine in both modes if the Ethernet cable is connected at start-up but I am having problems with DHCP if the cable is not plugged in when the application is started.

I cannot find the right sequence to restart the DHCP service once the maximum number of retries has been reached.

Can anyone advise what I need to do or point me in the direction of some example code to help me with this issue.

 

Thanks,

 

TJ
