A Python-based, open-source, platform-independent serial utility for flashing, provisioning, and interacting with Espressif SoCs. Visit the documentation or run esptool -h. If you're interested in contributing to esptool, please check the contributions guide. esptool was initially created by Fredrik Ahlberg (@themadinventor), and later maintained by Angus Gratton (@projectgus). It is now supported by Espressif Systems. It has also received improvements from many members of the community.

You can mark esptool as safe in your anti-virus SW, or install esptool from source. You will need Python 3.10 or newer installed on your system to use the latest version of esptool. If your use case requires Python 3.7, 3.8, or 3.9, please use esptool v4.x. For Python 2.7, 3.4, 3.5, or 3.6, please use esptool v3.3.* instead. The latest stable esptool release can be installed from PyPI via pip: With some Python installations this may not work and you’ll receive an error, try python -m pip install esptool or pip3 install esptool, or consult your Python installation manual for information about how to...

Setuptools is also a requirement which is not available on all systems by default. You can install it by a package manager of your operating system, or by pip install setuptools>=64. After installing, you will have esptool installed into the default Python executables directory and you should be able to run it with the command esptool or python -m esptool. Please note that probably only python -m esptool will work for Pythons installed from Windows Store. User friendly tools to manage ESP8266 and ESP32 devices in the browser: This demo will install ESPHome.

To get started, connect an ESP device to your computer and hit the button: ESP Web Tools works by combining Web Serial, Improv Wi-Fi (optional), and a manifest which describes the firmware. ESP Web Tools detects the chipset of the connected ESP device and automatically selects the right firmware variant from the manifest. Web Serial is available in Google Chrome and Microsoft Edge browsers (but not on your iOS device). Android support should be possible but has not been implemented yet. ESP Web Tools supports the Improv Wi-Fi serial standard.

This is an open standard to allow configuring Wi-Fi via the serial port. This document describes how to use esptool with the ESP32 SoC. To switch to a different SoC target, choose target from the dropdown in the upper left corner. Please note that this documentation is for the version of esptool v5. You can find your version in the command output or by running esptool version. For the version of esptool v4 please refer to the v4 documentation or pick from the dropdown in the upper left corner.

This is the documentation for esptool - a Python-based, open-source, platform-independent utility for flashing, provisioning, and interacting with Espressif SoCs. Esptool communicates with the ROM bootloader (or the flasher stub) in Espressif SoCs. The flasher stub is a small program included with esptool that replaces the original ROM bootloader in the chip to fix some of its limitations and bugs. See Flasher Stub for more details. esptool, espefuse and espsecure are a complete toolset for working with Espressif chips. They can do a number of things, for example:

A guide for setting up flashing your ESP projects directly from your browser ESP-Web-Tools allows your to flash your ESP directly from your browser using Web Serial API. This repo will provide the instructions needed to get this up and running. You should note that the Web Serial API has some requirements: You should also note that the sketchs that are uploaded will have to be generic ones, so can’t have configurations like WiFi details so please use something like WiFiManager to solve this, or you... I have put a lot of effort into creating Arduino libraries that I hope people can make use of.
