I'm strongly suggest you to look at ArduinoESP instead, there are plenty of sketches out there.
For example, for client, you will find it in libraries/ESP8266WiFi/examples/WiFiClient/WiFiClient.ino.
For the server while been in STA mode, there is libraries/ESP8266WiFi/examples/WiFiWebServer/WiFiWebServer.ino, but also one for AP mode in libraries/ESP8266WiFi/examples/WiFiAccessPoint/WiFiAccessPoint.ino
I will thank you.
