Digi ME uses temporary IP address before correct IP assigned


I am using the Digi Connect ME in an embedded app. It is configured as a TCP client and uses DHCP to configure its IP address. The temporary address make a connection to my TCP server and then once the temporary IP address has been replaced with one from the DHCP server that is in the correct subnet the ME connects to my TCP server again!!

I have recently upgraded the firmware to F5. My older firmware (rev A or B) did not exhibit this functionality.

Any thoughts as to what is going on here and how to stop this behaviour?

Many thanks,


If you are developing your own app, you should be able to add the following line to your appconf.h file to stop this:


If you are using the default firmware, I don’t know if it can be turned off or not.

Hope this helps.



I think I found it.

Clear the Enable AutoIP address assignment in the Advanced Network Settings section of the Network Configuration menu.

Thanks for givin me the direction to look in.
