// -- Wifi ----------------------------------------
#define WIFI_IP_ADDRESS "0.0.0.0" // [IpAddress1] Set to 0.0.0.0 for using DHCP or IP address
#define WIFI_GATEWAY "192.168.2.254" // [IpAddress2] If not using DHCP set Gateway IP address
#define WIFI_SUBNETMASK "255.255.255.0" // [IpAddress3] If not using DHCP set Network mask
#define WIFI_DNS "192.168.2.27" // [IpAddress4] If not using DHCP set DNS IP address (might be equal to WIFI_GATEWAY)
#define STA_SSID1 "" // [Ssid1] Wifi SSID
#define STA_PASS1 "" // [Password1] Wifi password
#define STA_SSID2 "" // [Ssid2] Optional alternate AP Wifi SSID
#define STA_PASS2 "" // [Password2] Optional alternate AP Wifi password
#define WIFI_CONFIG_TOOL WIFI_WPSCONFIG // [WifiConfig] Default tool if wifi fails to connect

So you're gonna need to use WPS. There's no default wifi setup in the minimal build.
