How to Save TCP / IP Parameters at Runtime in Non-volatile Memory

Basically, the configuration data that you want to store are IP addresses and other configuration information about the stack which are just numbers and strings. There is nothing special about how this data needs to be stored. To configure the stack, you need to read the data out of NVM and then call the appropriate MPLAB® Harmony TCP/IP APIs to configure the stack. You need to pass the configuration parameters to the APIs and you are responsible for formatting the data read from the NVM to a format that is required by the APIs.
