I'm new to networking and working with ESP8266. I have successfully setup my ESP8266 and can program it from Arduino IDE (tested a blinky code).
I want to send some data from a Python script running on my PC to ESP8266. Similar to a setup where use PySerial in Python, open a COM port and send my serial data to an Arduino. Arduino will parse my data bytes and will perform some action. Now, I am trying to achieve the same with ESP8266 and UART replaced with wireless communication.
First, I would like to connect my PC to ESP which will have its own SSID and password. Once connected, I would like to send my data bytes from Python script to ESP8266 wirelessly. Now, similarly, ESP will parse this received data and perform some function (like control its GPIOs).
How can I achieve this? It seems like a pretty simple task, but I'm really confused with what mode I've to use (AP? Client? Server?). What protocol for communication is the best (TCP? MQTT?). What do functions like Handle client/root do? I understand I've to use socket programming on Python, how to do that specifically in my case? How do I buffer my incoming data on ESP, so that I don't miss the bytes?
Could anyone please explain using an analogy with wireless communication and UART? Any links to tutorials will be helpful too. There are some tutorials online where they do this using a HTTP server and control the GPIOs from the browser, but no, I don't want this. I just simply want to send my data as I would with COM Port/UART/Arduino!
