RF SOLUTIONS ESP-07S Wi-Fi Module

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, a complete TCP/IP protocol stack. Users can use the add modules to an existing device networking or build 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. It has an 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 microcontroller-based 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 the 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.

Antenna interface

ESP-07S Modules through the IPEX interface to connect to an external antenna.
The antenna must be in line with the 802.11g/802.11b IEEE standard, and the antenna parameters are shown in the following table:

Package information and OEM installation method

Package information

ESP-07S use a half hole patch package, Module PCB Footprint is shown in the following figure:

OEM installation method

Using the ESP-07S module Please reference in front of the package information in the Layout on the mainboard for the OEM factory. Please pay more attention Module’s direction and the antenna close to the edge of the board is better, the Components and layout should not be on the bottom of the antenna then soldering the module. When the module be soldering cannot in an environment of high temperature. We recommend the reflow soldering temperature curves is shown in figure 6:

AT commend

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

AT Command Description

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

Notes:

1. Not all AT Command have 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”

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.

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.

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.

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.

Detailed instruction test, please refer to the Esp8266 AT Instruction Set, which can be downloaded to shun official website. AT+RESTORE – Factory reset
This command is used to reset all parameters saved in flash (according to the appendix) and restore the factory default settings of the module. The chip will be restarted when this command is executed.

Detailed instruction test, please refer to the Esp8266 AT Instruction Set, can be downloaded to shun official website.
