Hello
The following is some code I wrote some time ago to do what you are trying to do. You can safely ignore the peripheral code dealing with AWS and concentrate only on the code dealing with switching between DHCP and static and back.

- Function: void applicationTcpDown (void)
-
- Description:
-
-
This routine will be called by the NET+OS root thread once every
-
clock tick while it is waiting for the TCP/IP stack to come up.
-
This function can increment a counter everytime it's called to
-
keep track of how long we've been waiting for the stack to start.
-
If we've been waiting too long, then this function can do something
-
to handle the error.
-
-
This function will not be called once the stack has started.
-
- Parameters:
-
-
none
-
- Return Values:
-
-
none
-
*/
void applicationTcpDown (void)
{
static int ticksPassed = 0;
ticksPassed++;
/*
- Code to handle error condition if the stack doesn’t come up goes here.
*/
}

- Function: void applicationStart (void)
-
- Description:
-
-
This routine is responsible for starting the user application. It should
-
create any threads or other resources the application needs.
-
-
ThreadX, the NET+OS device drivers, and the TCP/IP stack will be running
-
when this function is called.
-
- Parameters:
-
-
none
-
- Return Values:
-
-
none
