change network parameters.

We take “Digi Weather Station Demo-ESP” demo based and digi Connect ME - C module use. And application define mac address in appconf.h file "#define APP_BSP_MAC_ADDRESS “00:40:9d:43:35:97"” line. We change the IP address, subnet mask and default gate away form web page. And we want to use module default(factory setup mac address) mac address because two or more module use in same network.
We don’t want to change default mac address, and also want to change IP address from web page.
