How can i send/recive Continous TCP socket Get/Request #3518
Description
Basic Infos
Hardware
Hardware: ESP8266-12E
Description
there are some codes available on "https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/WiFiWebServer/WiFiWebServer.ino" . I made the code work by modifying it a little but the main problem is that it Exchange data only once ,the server closes the connection when a one data exchanged .i want a continues TCP socket connection (send/receive )
