CCS/SIMPLELINK-CC3220-SDK: Adding custom data at provisioning time

Part Number:SIMPLELINK-CC3220-SDK

Tool/software: Code Composer Studio

Hello, 

I'd like to find a way to add custom data at provisoning time. It seems that using infoElement can help, but I don't really understand how to set a value when in AP mode.

I think the host can read such a value using sl_WlanGet, but I'd like a leased device to set it.

For example, I want to add a vendor specific string at provisioning time. I think I should enter a URL with my browser starting at simplelink page at gateway IP address where I can see all configuration data, but I'm not really sure.
