Hello, specialist friends!
I have a sketch that allows you to connect in two modes: AP mode to configure the network in which the ESP8266 will connect later in STA mode. The password and the name of the network that the user enters in the AP mode are stored in the EEPROM, so that if I do a reset, the sketch boots in STA mode accessing the network stored in the AP mode. The program works perfect. However, when in the LOOP if I add "WiFiClient client = server.available ();" to read wifi data, the compiler throws the error "'class ESP8266WebServer' has no member named 'available'", that is, it does not recognize the WiFi library.
Could you help me in telling me where the error is?
