the scan takes a fair amount of time. Instead, callback functions are used. The callback

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
access point as, for example,
or use an empty string, "", to associate with the strongest BSS available.
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.
