Using ESP8266 Wifi Transceiver Module with SDK

The ESP8266 Soc. ESP8266 is a highly integrated chip that has TCP/IP Protocol stack. It’s offers a complete and self contained Wi-Fi Network Communication Solution, allowing it to either host the application or offload all Wifi function from another application process. ESP7155 it has a powerful onboard processing and storage capabilities that allow it to integrated with the sensors and other application specific devices thought its GPIO(General Input Outputs with minimal development up-front and minimal loading during runtime. Its high and accurate on chip integration allows for minimal external circuitry and the entire solution, including front end module is designed to occupy minimal PCB area
