i aspire to be able to code like you and many others do, code as if it's speaking in one's native language. thank you for this!

Thank you so much for the tutorial! It really helped me to kickstart the network programming for my personal project. Briefly explaining my goal, I am trying to control my RPi LED matrix programmed with C++ through a Unity3D mobile application. I am setting up a separate RPi socket server for the two clients; one is the smartphone app, and the other one is the RPi LED matrix. I want these two clients to talk through the local socket server. I am just starting to learn socket programming and pretty much C++ too. If what I am planning doesn't make sense to you, please let me know. It would be great to hear your advice.

After seeing your tutorial, I am digging into ASIO. I am having a hard time reading their documentation. I don't see what constructor or function parameters I need to use. For an example of creating an acceptor object, where can I find the information about the parameters? I see only small examples at the bottom. Is that all?

I know there is websocket++ based on ASIO. Could you give a tutorial about the WebSocket implementation with RPi?

Lastly, if I want to use a cloud socket server instead of a local server, which is perfectly fine for now, what is a good and simple way to have this remote socket server I can connect to? (Rpi LED (programmed with c++) <-> Cloud Server <-> Smartphone(programmed with c#) is the structure.
