Wiring & Programming ESP8266 12/12E / NodeMCU as WiFi

You need to keep track of multiple WiFiClients - declare an array of them, for example, and each time server.available() gives you a new one, store it in the array.. Then you need to make sure your code doesn't stick waiting for data from each item. You could service each WifiClient in turn: if it has data waiting (client[i].available() is true), read the data (client[i].read()) and store it In loop() function you will have to program what happens when a new client establishes a connection with the web server. The ESP8266 is always listening to the incoming clients using server.available(); and store the incoming data to a string variable and print the data on the serial monitor Im folgenden Programm habe ich einen Server ESP8266 und einen Client ESP8266. Miteinander verbinden geht alles soweit nur bekomme ich es mit der Übertragung von Daten (also z.B. einem Byte) nicht gebacken.
