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. Espressif also offers a graphical tool to simplify this process. An important features that simplify the sharing of firmware (and It is used by the most productor) is to generate pre-compiled binary file with only the sketch part (or filesystem). Next go to API TEST->Flash Image Download. esp8266: flash compiled firmware and filesystem (.bin) with GUI tools 2. 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. 1.6) TX with Arduino TX, and RX with Arduino RX. A quick 'blue blink' occurs when you connect and remove RST pin from Arduino GND. You must connect it in Arduino GND only to reset the current ESP firmare, and remove it for update the firmware. 1.5) RST pin is used only to reset the ESP module.

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). GPIO0 in GND is to enable programming in ESP8266. 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.

"#file-input,input else if (upload.In this tutorial we will show how to update ESP8266 with new firmware. If you want to learn more about Basic OTA, please check this tutorial out. You can implement any one according to your project’s requirement.īelow tutorial covers web updater OTA implementation. Just write a simple YAML configuration file and get your own customized firmware. When I first got introduced to the world of the ESP8266, I had a real hard time to find a way to flash the firmware of the ESP8266-01 with an Arduino Uno.

There are two ways to implement OTA functionality in ESP32. This is very handy if you wish to install a device such as the Wemos D1 Mini in a remote location and still need to make firmware updates.

The only disadvantage is that you have to add an extra code for OTA with every sketch you upload, so that you’re able to use OTA in the next update. One important feature of OTA is that one central location can send an update to multiple ESPs sharing same network. It helps reduce the amount of time spent for updating each ESP module at the time of maintenance. OTA functionality is extremely useful in case of no physical access to the ESP module. The OTA programming allows updating/uploading a new program to ESP32 using Wi-Fi instead of requiring the user to connect the ESP32 to a computer via USB to perform the update.

This is known as Over-The-Air (OTA) programming. If ESP8266 is flashed with Arduino program to access GPIO pins, then the existing firmware of ESP8266 will be completely erased and Arduino code will be uploaded to that module. A fantastic feature of any WiFi-enabled microcontroller like ESP32 is the ability to update its firmware wirelessly. Before installing the new firmware into ESP8266, we can check the current firmware version of ESP8266 module by using Arduino IDE serial monitor.
