Re: [lwip-users] DHCP callback was removed - Correct way to obtain new address?

[Paul Webber]

Chris,

I am using the TCP RAW. After starting DHCP I wait for the IP by using: While(main_netif.dchp->state != DHCP_BOUND). After the state changes to DHCP_BOUND the ip is in the pcb (main_netif.ip_addr). You can periodically check to see if the ip changes. I also include in the while statement a timer in case there is a DHCP problem.

Subject: [lwip-users] DHCP callback was removed - Correct way to obtain new address?

 

Hi all,

 

I am just porting my application from version 1.3.2 to the latest 1.4.2. and I was wondering why my application does not get called back from the stack when the DHCP

 

As I found out the callback was removed. My application has to know the address for displaying purposes, so do I have to poll for a new address?

 

What is the proper way to obtain a new address?

 

Regards

 

Chris
