Select firmware image and press button Download.Ĭurrent EasyIoT8266 Arduino library works with ESP8266 V0.9.5.2 firmware. 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.

#Update esp8266 firmware how to#
GPIO0 = Normally floating but this needs to be grounded when you start the update. How to flash nodemcu firmware into a ESP8266 so you can use the LUA scripting language.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.
