AT Command driver for ESP8266 which uses UART to communicate with STM32 to provide WiFi connectivity. Please follow the readme file. If it seems too much in the beginning to incorporate drivers. Then, I'll suggest first configuring ESP8266 in AT command Mode. And then write individual AT command over UART from STM32 to host a simple webserver. I don't have any specific video on the top of my head. But heres GitHub repo https://github.com/jrmejiaa/ESP8266
