Connecting ESP8266 with STM32F103C8: Creating a Webserver

This project integrates the ESP8266 Wi-Fi module with an STM32F103C8 Blue Pill microcontroller to establish a foundational Internet of Things (IoT) web server architecture. The STM32F103C8 acts as the primary embedded processing unit, managing local tasks, while the ESP8266 functions as a network bridge, connecting to a local Wi-Fi router or hotspot. Communication between the STM32 board and the ESP8266 module typically occurs over a serial interface using AT commands or custom serial firmware programmed via the Arduino IDE. When a user on a laptop or computer connects to the network and enters the ESP8266's assigned IP address into a web browser, an HTTP request is transmitted over the Wi-Fi hotspot to the ESP8266. The ESP8266 relays this command to the STM32 Blue Pill using connecting wires. Upon receiving the instruction, the STM32 processes the request and can return system status or data back through the ESP8266, which renders the lightweight web interface on the client's browser. This setup effectively bridges wired microcontroller hardware with wireless network protocols, enabling remote interaction suitable for applications like smart pill dispensers.
