I'm currently trying to make my Arduino UNO WiFi work as a TCP host, so I can send him a TCP message and it sends a response.

I had no problem doing this on the Arduino Galileo Gen 2 using the EthernetServer, but since this one is using WiFi, EthernetServer isn't an option.

I can, however, run a web server, but that's not what I want.

So how do I make the Arduino receive, handle and respond to sent TCP/IP messages?

For Arduino UNO Wifi, you have to use library "UnoWiFi-Developer-Edition-Lib". You can directly download and install it through library manager or can get it offline through the following link "https://github.com/arduino-libraries/UnoWiFi-Developer-Edition-Lib".

Hope this can help you.

Ethernet and wifi are basically the same thing but only joinig Ethernet is codewise different than joining a wifi address and thus these two need 100% different code because wifi and Ethernet are a different thing.

See, compare codes in below links, and you see the difference is on making up the level 1 connection, and tcp and ip on 2 and 3 do not change.
