Built-in PLL, voltage regulator, and power management components, +20dBm output power in 802.11b mode.Built-in TR switch, balun, LNA, power amplifier and matching network.Built-in Tensilica L106 ultra-low-power 32-bit micro MCU, clocked at 80 MHz and 160 MHz, supporting RTOS.The ESP8266 comes in a wide variety of versions (as shown in the figure below). It is faster than most Arduino boards and has more memory than most Arduino boards and has less pins than an Arduino board. In short, the ESP8266 module is a TTL "Serial to Wireless Internet" device, a small microprocessor with built in wi-fi.
The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs (General Purpose Input Output) with minimal development up-front and minimal loading during runtime. The ESP8266 WiFi Module is an extremely cost effective board. The ESP8266 WiFi Module is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.Įach ESP8266 WiFi Module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino board and get about as much WiFi-ability as a WiFi Shield offers. The ESP8266 WiFi Module is a self contained SOC (System On a Chip) with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network.
We will learn how to update the firmware in ESP8266 ESP-01 WI FI module.

If you are usning SW serial, set baudrate to 9600 (default is 115200) with AT+CIOBAUD=9600. Next go to API TEST->Flash Image Download. Select Com port (only Com ports COM1-COM6 are supported - change port in Windows control panel if necessary). Run program and go to Tools->Config device. Program can be downloaded here XTCOM_UTIL. I'm using Windows XTCOM_UTIL, but you can find more flashing utilities on internet.
I've connected ESP8266 VCC to additional 3.3V power supply (do not connect FTDI serial USB VCC to VCC power supply if you are using additional power supply). In my case serial USB converter did not provide enough current and updating was impossible. URXD = Rx data connect to Rx of FTDI/Serial interface.UTXD = Tx data connect to Txd on FTDI/Serial interface.GPIO0 = Normally floating but this needs to be grounded when you start the update.RST = Leave floating or ground to reset.
Don't forget to s et FTDI programmer to 3.3V. To upload ESP8266 firmware you need FT232RL FTDI USB to TTL Serial+Adapter.
The problem is if we do not need correct ESP8266 firmware, because responses to AT commands are different in different firmware versions.
We use ESP8266 together with Arduino and ESP8266EasyIoT library. In this tutorial we will show how to update ESP8266 with new firmware.
