The data passed to the callback function are ephemeral since another scan may occur.
Thus, the data need to be used (or copied) during the callback function.
While waiting for user input, it is important to keep the network alive by calling

If you are not using DHCP, set the IP parameters to values appropriate to your network.
Set the macro IFC_WIFI_SSID= to define a C-style string to set the SSID of your

Alternatively, you may create your own CUSTOM_CONFIG.LIB library modeled on the
Dynamic C TCP_CONFIG.LIB library. Then use a TCPCONFIG macro greater than or
equal to 100, which will invoke your CUSTOM_CONFIG.LIB library to be used.
Remember to add the CUSTOM_CONFIG.LIB library to LIB.DIR.
