AT+CWMODE=2: Configure ESP8266 as Access Point

The 'AT+CWMODE=2' command is used to configure the ESP8266 Wi-Fi module to operate as an access point. This means the ESP8266 will create its own wireless network that other devices can connect to.

This command is essential for building projects where the ESP8266 needs to act as a central hub for other devices, allowing them to connect and communicate with each other through the ESP8266's network.
