You can use a SPDT switch to achieve this action i.e.

And after flashing the Firmware, I’ve disconnected it from GND.

I’ve connected the GPIO0 Pin to GND directly.

Before proceeding further, please refer the previous project for configuring Arduino IDE and getting the Arduino UNO ready for flashing the firmware.

In order to put the ESP8266 SoC in Flashing Mode, the GPIO0 Pin must be connected to GND and a momentary GND Pulse on RST Pin. The following image shows the circuit diagram for enabling the Flashing Mode in ESP8266.

We will implement the same setup here as well. If you remember in the GETTING STARTED WITH ESP8266 AND ARDUINO project, I’ve mentioned that GPIO0 and RST Pins of the ESP8266 Module play an important role in configuring it in Download Mode. Hardware Setup for ESP8266 Firmware Updateīefore proceeding into the process of updating the ESP8266 SoC’s Firmware, it is important to configure the ESP8266 WiFi Module in Download Mode or Programming Mode.

ESP8266 FIRMWARE TO WORK WITH ARUDIONO INSTALL

The ESP8266 Firmware can be installed for two reasons: If you want to update the ESP8266 Firmware to its latest version or to completely install the new firmware (in case it was overwritten by any program).

So, in this project, we will flash the official Espressif Systems’ firmware for ESP8266 Module using the official ESP8266 Flasher Tool provided by Espressif Systems which is the ESP8266 FLASH DOWNLOAD TOOL and Arduino UNO as the USB to Serial Interface. This leads to a lot of questions like whether the firmware is original or not, is the firmware up to date or not and many other.

In my case, I have the ESP8266 ESP-01 Module by AI-Thinker. In the same project, I’ve mentioned that by default, the ESP8266 ESP-01 Module comes with an AT Command Firmware.īut if we write our own program to access the GPIO Pins (like we did in the previous project), the existing firmware will be completely erased and the new program will be written.Įven though ESP8266 WiFi Module is manufactured by Espressif Systems, the SoC is used by many third party manufacturers to implement their own custom modules.

ESP8266 FIRMWARE TO WORK WITH ARUDIONO HOW TO

In the previous ESP8266 Project, we have seen how to write our own program in ESP8266 using Arduino IDE and control an LED using the GPIO Pins. This project can also be used if you want to update to the latest ESP8266 Firmware. This is the second project on ESP8266 and in this project, I’ll show you how to flash the Official Espressif Firmware in ESP8266 using Arduino.
