In order to configure the ESP as server you should enable multiple connections to ESP( CIPMUX=1).The user can configure the ESP 8266 as server by following commands.
You will get a SEND OK after sending the data as shown below.ĮSP8266 Communication with other WiFi modules: ESP8266 as a Server Send the exact data with data length which is mentioned in the AT+CIPSEND= command.
Controlled via UART interface at 115200 baud with a simple set of AT commands.Support three modes: AP, STA and AP+STA coexistence mode.The AT command is perfect,efficient,concise.You can use AT commands to connect to WiFi networks and open TCP connections without need to have TCP/IP stack running in your own microcontroller: You can simply connect any microcontroller to this module and start pushing data up to the Internet. ESP-01 WIFI Transceiver Module is addressable over SPI and UART, making this an exceptionally easy choice for anyone wanting to build an Internet of Things thing. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

This is quite convenient as it only requires two wires (TX/RX) to communicate between a micro-controller and WiFi, but more importantly, it offloads WiFi-related tasks to the module, allowing the microcontroller code to be very light-weighted.ĮSP8266 ESP-01 Serial WIFI Transceiver Module is a cheap and easy way to connect any small microcontroller platform, like Arduino, wirelessly to Internet. ESP8266 is a new player in this field: it’s tiny (25mm x 15mm), with simple pin connections (standard 2×4 pin headers), using serial TX/RX to send and receive Ethernet buffers, and similarly, using serial commands to query and change configurations of the WiFi module. With the popularity of Wifi IoT devices, there is an increasing demand for low-cost and easy-to-use WiFi modules.
