MSP432E401Y: Changing Static IP address in runtime

Hi,

I used tcpEcho example as basis and changed NDK Interface to have static IP using sysconfig. Now I am trying to write a code that will change this static IP address upon a request. I looked into older forum entries and the suggestion was  to edit the parameters of ti_ndk_config_ip_init() function. However since this function was created sysconfig tool I cannot edit. I also tried to have my own function that can change these parameters. Any ideas how can I solve this problem? 

Thanks in advance.
