[ME 9210] - How to use the DHCP client?

How to use the DHCP client.


I would like to know how to use the DHCP client module with DIGI ME 9210.
When creating the project I have enabled:
Linux Kernel Configuration / Networking support / Networking options / TCP / IP networking / IP: kernel level autoconfiguration / IP: DHCP support

Is it necessary to start then a deamon?

I developed a program in C that will work on this module 9210, I need to activate or not the DHCP function.

Thank you for your help.

ok I just start udhcpc.
