## 1. Preambles 

ESP-07S WiFi module is developed by AI-Thinker Co.,Ltd, core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antennas. 

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.

Espressif AT instruction set functions and methods of use 

AT commands set is divided into: Basic AT commands, WiFi related AT commands, TCP / IP AT 

## 4.3.1.AT Command Description 

Table 8 Each Command set contains four types of AT commands. 

Notes: 

1. Not all AT Command has four commands. 

2. [] = default value, not required or may not appear 

3. String values require double quotation marks, for example: 

AT+CWSAP="ESP756290","21030826",1,4 

4. Baudrate = 115200 

5. AT Commands has to be capitalized, and end with "/r/n" 

## 4.3.2.Basic AT Command Set 

The ESP8266 wireless WiFi modules can be driven via the serial interface using the standard AT 

commands. Here is a list of some basic AT commands that can be used.

ESP-07S User Manual 

Table 9 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. 

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.

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.
