The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the add modules to an existing device networking, or building a separate network controller. ESP8266 is high integration wireless SOCs, designed for space and power constrained mobile platform designers. It provides unsurpassed ability to embed Wi-Fi capabilities within other systems, or to function as a standalone application, with the lowest cost, and minimal space requirement. Figure 1 ESP8266EX Functional Block Diagram ESP8266EX offers a complete and self-contained Wi-Fi networking solution; it can be used to host the application or to offload Wi-Fi networking functions from another application processor. When ESP8266EX hosts the application, it boots up directly from an external flash. In has integrated cache to improve the performance of the system in such applications. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any micro controllerbased design with simple connectivity (SPI/SDIO or I2C/UART interface). ESP8266EX is among the most integrated WiFi chip in the industry; it integrates the antenna switches, RF balun, power amplifier, low noise receive amplifier, filters, power management modules, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor, with on-chip SRAM, besides the Wi-Fi functionalities. ESP8266EX is often integrated with external sensors and other application specific devices through its GPIOs; codes for such applications are provided in examples in the SDK.

Here is a list of some basic AT commands that can be used. Shenzhen Ai-Thinker Technology Co., Ltd http://www.ai-thinker.com 12 ESP-07S User Manual Table9 basic AT commands AT – Test AT startup The type of this command is "executed". It's used to test the setup function of your wireless WiFi module. Shenzhen Ai-Thinker Technology Co., Ltd http://www.ai-thinker.com 13 ESP-07S User Manual AT+RST – Restart module The type of this command is "executed". It’s used to restart the module. AT+GMR – View version info This AT command is used to check the version of AT commands and SDK that you are using, the type of which is "executed". AT+GSLP – Enter deep-sleep mode This command is used to invoke the deep-sleep mode of the module, the type of which is "set". A minor adjustment has to be made before the module enter this deep sleep mode, i.e., connect XPD_DCDC with EXT_RSTB via 0R. Shenzhen Ai-Thinker Technology Co., Ltd http://www.ai-thinker.com 14 ESP-07S User Manual ATE – AT commands echo This command ATE is an AT trigger command echo. It means that entered commands can be echoed back to the sender when ATE command is used. Two parameters are possible. The command returns "OK" in normal cases and "ERROR" when a parameter other than 0 or 1 was specified. AT+RESTORE – Factory reset This command is used to reset all parameters saved in flash (according to appendix), restore the factory default settings of the module. The chip will be restarted when this command is executed.
