MQX How to change IP address, restart RTCS and/or HTTP

[chinniwhites]

I have a custom K60 board with Ethernet and I am running basically a custom version of httpserv example.  I have a webpage where I have my ip, subnet, and gw settings so user can change ip address - very standard stuff when talking Ethernet device.  In MQX, what is the process needed to get the ip address change to actually take affect.  My first attempt involved destroying the HTTP_TASK and then recreating the task but rtcs gave me an error 1300 probably because i tried to create an rtcs that was already running.

So to change IP address, do I stop HTTP, unbind, rebind, start HTTP server?

Is there a simple way to make an IP change take affect?

I am using ipcfg_unbind instead of RTCS_if_unbind since httpserv demo uses ipcfg functions in replacement of RTCS functions everywhere else in program.

After my unbind, I get error 10419 returning for ipcfg_init_device function.

What gives?

void rtcs_init()

{

   IPCFG_IP_ADDRESS_DATA ip_data;

   _enet_address           enet_address;

   uint32_t error;

   if (rtcs_started == 0){

       error = RTCS_create();

       if (error != RTCS_OK)

       {

          printf("\nRTCS failed to initialize, error = %X", error);

          _task_block();

       }

       _IP_forward = TRUE;

   }

   else{

       ipcfg_unbind(ENET_DEVICE);

Hello,

Which MQX version are you using?

Could you please check the below threads??
