Common Issues¶
Here are some of the most common issues around the ESP32 development using Arduino.
Note
Please consider contributing if you have found any issues with the solution here.
Installing¶
Here are the common issues during the installation.
Building¶
Missing Python: “python”: executable file not found in $PATH¶
You are trying to build your sketch using Ubuntu and this message appears:
"exec: "python": executable file not found in $PATH Error compiling for board ESP32 Dev Module"
Solution¶
To avoid this error, you can install the python-is-python3 package to create the symbolic links.
sudo apt install python-is-python3
If you are not using Ubuntu, you can check if you have the Python correctly installed or the presence of the symbolic links/environment variables.
Flashing¶
Why is my board not flashing/uploading when I try to upload my sketch?¶
To be able to upload the sketch via serial interface, the ESP32 must be in the download mode. The download mode allows you to upload the sketch over the serial port and to get into it, you need to keep the GPIO0 in LOW while a resetting (EN pin) cycle.
If you are trying to upload a new sketch and your board is not responding, there are some possible reasons.
Possible fatal error message from the Arduino IDE:
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
Solution¶
Here are some steps that you can try to:
-
Check your USB cable and try a new one.
-
Change the USB port.
-
Check your power supply.
-
In some instances, you must keep GPIO0 LOW during the uploading process via the serial interface.
-
Hold down the “BOOT” button in your ESP32 board while uploading/flashing.
In some development boards, you can try adding the reset delay circuit, as described in the Power-on Sequence section on the ESP32 Hardware Design Guidelines in order to get into the download mode automatically.
Hardware¶
Why is my computer not detecting my board?¶
If your board is not being detected after connecting to the USB, you can try to:
Solution¶
-
Check if the USB driver is missing. — USB Driver Download Link
-
Check your USB cable and try a new one.
-
Change the USB port.
-
Check your power supply.
-
Check if the board is damaged or defective.
Wi-Fi¶
Why does the board not connect to WEP/WPA-“encrypted” Wi-Fi?¶
Please note that WEP/WPA has significant security vulnerabilities and its use is strongly discouraged.
The support may therefore be removed in the future. Please migrate to WPA2 or newer.
Solution¶
Nevertheless, it may be necessary to connect to insecure networks. To do this, the security requirement of the ESP32 must be lowered to an insecure level by using:
WiFi.setMinSecurity(WIFI_AUTH_WEP); // Lower min security to WEP. // or WiFi.setMinSecurity(WIFI_AUTH_WPA_PSK); // Lower min security to WPA.
Why does the board not connect to WPA3-encrypted Wi-Fi?¶
WPA3 support is resource intensive and may not be compiled into the used SDK.
Solution¶
-
Check WPA3 support by your SDK.
-
Compile your custom SDK with WPA3 support.
Sample code to check SDK WPA3 support at compile time:
#ifndef CONFIG_ESP32_WIFI_ENABLE_WPA3_SAE #warning "No WPA3 support." #endif

CODE
/*
WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will print the IP address of your WiFi Shield (once connected)
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 5.
If the IP address of your shield is yourAddress:
http://yourAddress/H turns the LED on
http://yourAddress/L turns it off
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
Circuit:
* WiFi shield attached
* LED attached to pin 5

Вопрос:
Я работаю над DOIT ESP32 DEVKIT V1 и использую Arduino IDE 1.8.13 (Windows 10 Pro Education x64) для кодирования этой платы. Я установил плату ESP32 (и ESP8266) также из менеджера плат внутри Arduino IDE. Он работал нормально в течение нескольких дней, пока один друг не прислал мне файл .ino, и после того, как он открыл его и попытался скомпилировать и загрузить этот файл на мою доску, произошла странная ошибка компиляции (это та же ошибка, которая произошла в системе моей подруги, и ей пришлось переключиться на другую систему, чтобы продолжить бесперебойную работу). Я использую эти URL-адреса вДополнительные URL-адреса менеджера плат в разделе «Настройки» в среде IDE Arduino:
https://dl.espressif.com/dl/package_esp32_index.json, http://arduino.esp8266.com/stable/package_esp8266com_index.json
И при компиляции появляются следующие сообщения об ошибках:

Error compiling for board DOIT ESP32 DEVKIT V1.
Пожалуйста, предоставьте мне пошаговое руководство по устранению этой проблемы, так как я новичок в таких ошибках и проблемах с каталогами. Обратите внимание, что при выборе плат Arduino AVR (таких как MEGA, UNO и т. Д.) Ошибок компиляции не возникает. Я уже пытался переустановить плату ESP32 из диспетчера плат, но безуспешно.
Комментарии:
1. удалите папку пакета поддержки плат
esp32, а затем попробуйте установить его снова2. Спасибо @Juraj, это сработало! Проблема была в папке. На самом деле никакой папки не было. Поэтому я вручную создал папку и установил в нее ядро. ИСПРАВЛЕНО! 🙂
Ответ №1:
ИСПРАВЛЕНО! Проблема заключалась в том, что нигде не было папок /hardware/espressif/esp32, несмотря на то, что была установлена поддержка платы. Поэтому я удалил плату из менеджера платы Arduino, сам создал папки и установил в них ядро ESP32. Я следовал всем инструкциям, приведенным по этой ссылке: https://learn.sparkfun.com/tutorials/esp32-thing-hookup-guide/installing-the-esp32-arduino-core
Они предоставили все шаги (включая создание папок/каталогов) для установки ядра через репозиторий github. И теперь ошибка исправлена, и она работает отлично!

followed the directions (today) here:
https://github.com/espressif/arduino-esp32/blob/master/doc/windows.md
and tried to verify/compile a range of basic sketches. all throw the same error. I am using the ESP32 Thing by sparkfun.
One variance is that I had to manually install the requests module for python before i could run python get.py

Error compiling for board ESP32 Dev Module.
seems that I need to test this on Windows.. maybe the new toolchain or something. no issues on a Mac.
let me know if there is something i can help with. note all my installs are 64 bit. (Arduino, Python, etc)
+1, just received the module and have the same error message. (Win 10, X64. Arduino 1.6.10 hourly Build)
Confirmed to work OK with Arduino 1.8.1 on Linux SuSE 13.2.
you windows guys can try the old toolchain from here and please do report if working
if it complains about missing impure_ptr, add this to your sketch:
void *operator new(size_t size) { return malloc(size); } void *operator new[](size_t size) { return malloc(size); } void operator delete(void * ptr) { free(ptr); } void operator delete[](void * ptr) { free(ptr); } extern "C" void __cxa_pure_virtual(void) __attribute__ ((__noreturn__)); extern "C" void __cxa_deleted_virtual(void) __attribute__ ((__noreturn__)); void __cxa_pure_virtual(void) { abort(); } void __cxa_deleted_virtual(void) { abort(); }
Last two posts solves my problem on Windows 10 64bit, Arduino IDE 1.8.1 64bit and python 2.7.12 64bit
thx me-no-dev
Older toolchain and and impure_ptr fix works for me too (Win 7 64bit, Arduino 1.8.0, python 2.7.12)
Thanks me-no-dev.
confirmed. with the impure_ptr fix.
+1 works with older toolchain and required impure_ptr fix. Also I had to hold button to download after 10 attempts. Seems esp_tool.py may be more touchy connecting to dev module than in the past.
Arduino: 1.8.1 (Windows Store 1.8.1.0) (Windows 10), Board: «ESP32 Dev Module, 80MHz, 921600», Python 2.7.13 (with added pip install requests)
alright guys toolchain updated and new get.exe added next to get.py. Git pull the repo and doubleclick get.exe to update the toolchain
Clean clone then get.exe instead of get.py and all works fine 1) I see updated Windows directions so no concerns over import requests, 2) no issue with compiler error. 3) no more issue with impure_ptr. Looks good — thanks.
Confirmed good sir. looks good!
Awesome now let’s add binary esptool so users would have only git as dependency
@hoopsurfer I also noticed on Windows esptool to have harder time to reset the board. Will ask around
igrr
mentioned this issue
Jan 23, 2017
alright guys
toolchain updated and new get.exe added next to get.py. Git pull the repo and doubleclick get.exe to update the toolchain
Thank you me-no-dev! It looks like you have the fix! But I’m lost. Sorry — total noob to Arduino/ESP32/Git/Python/… I downloaded and extracted «xtensa-esp32-elf-win32-1.22.0-59 (1).zip». Now What? Can you explain the above for a slow learner?
@me-no-dev I’m getting the same error with both the new toolchain and the old one that you posted, I’m running Win 8.1 x64, Arduino 1.8.5, and the esp 32 dev kit v1 by «do it» this is the error:
exit status 1
Error compiling for board ESP32 Dev Module.
Do you have any suggestions?
@jjimmy-S after recommended installation, in the last where you have to run get.exe, did it throw any error message? I think in your case the toolchain was not installed. If get.exe throws errors you can this.
Or you can install the toolchain and other tools manually.

У ESP32 есть несколько распространенных проблем, особенно когда вы пытаетесь загрузить новые скетчи или установить плату ESP32 в Arduino IDE. Это руководство посвящено неполадкам ESP32 при программировании ее в среде Arduino. Здесь мы приведём список наиболее распространенных проблем с ESP32, а также расскажем, как исправить их.
Важно: убедитесь, что у вас установлена последняя версия Arduino IDE. Использование другой версии Arduino IDE может вызвать непредвиденные проблемы и ошибки.
Как мне установить пакет ESP32 для Arduino IDE?
Существует пакет ESP32 для среды Arduino, который позволяет вам программировать плату в Arduino IDE. Итак, по порядку:
- В среде Arduino переходим Файл > Настройки;
- В графе дополнительные ссылки для менеджера плат указываем эту ссылку: https://dl.espressif.com/dl/package_esp32_index.json
- Затем переходим в Инструменты > Плата “Arduino UNO” > Менеджер плат, вбиваем в поиске esp32 и устанавливаем пакет для платы.
Не отображается плата ESP32 в меню инструментов Arduino
Если плата не отображается в Arduino IDE, убедитесь, что вы щелкнули по маленькой стрелке (выделенной на рисунке ниже), чтобы найти свою плату:
Если и в этот раз вы не можете найти название своей платы ESP32, рекомендуем повторить процесс установки с нуля.
C:/Users/User/Documents/Arduino/hardware/espressif/esp32/ tools/xtensa-esp32-elf/bin/xtensa-esp32-elf-g ++ »: файл не существует
Если Arduino IDE не может скомпилировать код для платы ESP32 и выдает данную ошибку, рекомендуем переустановить ESP32.
Примечание. На ПК с Windows часто установлено несколько версий Arduino IDE (portable и устанавливаемая). Убедитесь, что вы используете то приложение Arduino, в которое вы установили ESP32.
Не удалось подключиться к ESP32: время ожидания истекло… Подключение…»
В данном случае при попытке загрузить скетч на плату приложение не может подключиться к ней. Это значит, что ESP32 не находится в режиме прошивки / загрузки.
Выполните следующие действия:
- Удерживайте кнопку «BOOT » на плате ESP32.
- Нажмите кнопку «Загрузка» в Arduino IDE, чтобы загрузить новый скетч:
- После того, как вы увидите «Connecting…. » в Arduino IDE, уберите палец с кнопки «BOOT» :
- После этого, вы должны увидеть сообщение о завершении загрузки
Вот и все. На ESP32 должен быть загружен новый скетч. После загрузки нового скетча нажмите кнопку «ENABLE», чтобы перезапустить ESP32 и запустить загруженный скетч.
Ошибка при компиляции скетча WiFiScan
Если вы попытаетесь загрузить скетч ESP32 WiFiScan.ino, который есть в примерах
И он не может скомпилироваться с подобным сообщением об ошибке:
|
In function ‘void setup()’: ScanNetworks:52: error: ‘class WiFiClass’ has no member named ‘firmwareVersion’ String fv = WiFi.firmwareVersion(); |
То вероятнее всего, среда Arduino компилирует библиотеку WiFi для платы Arduino (вместо использования библиотеки ESP32 WiFi).
Примечание: Вы, вероятно, никогда не будете использовать WiFi-экран с платой Arduino, так ведь? Если вы его не используете, вы можете удалить эту папку (ну или переместить ее на рабочий стол, например).
Библиотека WiFi находится по аналогичному пути:
C:UsersruisantosDownloadsarduino-1.8.7-windowsarduino-1.8.7librariesWiFi
И /или в:
C:UsersruisantosDocumentsArduinolibrarieslibrariesWiFi
После удаления всей папки библиотеки WiFi из одного или обоих мест перезапустите Arduino IDE и попробуйте снова скомпилировать код.
COM-порт не найден / недоступен
Если вы подключаете плату ESP32 к компьютеру, но не можете выбрать порт ESP32, доступный в вашей Arduino IDE (он неактивен):
Это может быть одна из следующих двух проблем:
- Отсутствуют драйверы USB;
- Кабель USB не имеет проводов для передачи данных.
Если вы не видите доступный COM-порт вашего ESP, это может означать, что у вас не установлены драйверы USB. Присмотритесь к микросхеме рядом с регулятором напряжения на плате и проверьте ее название.
Плата ESP32 DEVKIT V1 DOIT, например, использует чип CP2102.
Зайдите в поисковик и найдите свой чип, установите драйверы для него.
Вы можете скачать драйверы CP2102 на сайте Silicon Labs.
После их установки перезапустите Arduino IDE, и вы должны увидеть COM-порт в меню «Инструменты».
Если у вас установлены драйверы, но вы не видите свое устройство, еще раз проверьте, что вы используете USB-кабель с проводами для передачи данных.
USB-кабели от внешних аккумуляторов часто не имеют проводов для передачи данных (они только заряжают). То есть, ваш компьютер не сможет установить последовательную связь с ESP32. Используйте другой USB-кабель.
Монитор порта в Arduino IDE «не работает»
Если ESP32 выводит только странный текст или бессвязные сообщения в мониторе порта среды Arduino, убедитесь, что у вас выбран правильный COM-порт, и установите правильную скорость передачи. В большинстве примеров используется скорость 115200 бод.
Ошибка: «Brownout detector was triggered»
Когда вы открываете монитор порта и появляется повторяющееся сообщение об ошибке «Brownout detector was triggered», скорее всего это значит, что есть какая-то проблема с оборудованием.
Это часто связано с одной из следующих проблем:
USB-кабель плохого качества;
Слишком длинный USB-кабель;
Дефект в плате (плохо припаянные соединения);
Неисправный USB-порт на ПК;
Через USB-порт на ПК идет недостаточно питания.
Решение: попробуйте другой более короткий USB-кабель, попробуйте другой USB-порт компьютера или используйте USB-концентратор с внешним источником питания.
Плата ESP32 не работает с Arduino IDE
Если вы следовали всем советам по устранению неполадок, а ESP32 не работает с Arduino IDE, мы рекомендуем попробовать редакторы Atom и PlatformIO.

You’ve probably tried these already, but if not, it might help a little.
While this might not fix things for you, in my experience, running working Arduino Code on an ESP32 usually works fine (after tweaking GPIOs). Sometimes you need to also add #include <Arduino.h> or #include <SPI.h> or #include <Wire.h>, or all of them at the very least!
You didn’t mention what the filename is of your sketch… ?? Does it end with .c ?? If so, rename it to .cpp. This has caught me out a few times when I started out.
Other than that, you might want to add some more info. It might be the libraries (#include lines in your sketch) aren’t quite compatible with your board too, in which case, you’ll have to dig deep, and it won’t be for the faint-hearted / undetermined / those who swerve a challenge!
Good luck!

In this case, the library is just written shoddily and the compiler refuses to compile the crap in it:
Code: Select all
m = buff[1] == 'a' ? 1 : m = buff[2] == 'n' ? 6 : 7;
It’s entirely unclear what m is supposed to be here, as it’s assigned twice to two different values in one operation.

Thank you Tinker and Sprite. Still no joy yet.
This library was written in 2016 by JeeLabs (aka J.C. Wipple) who usually does good work.
I am just a hobbyist and certainly not a geek, but it seems that the problem lies with some conversions or interpretations between the Arduino IDE and the ESP32 dev board. There are several examples in this library and they all work with a UNO, but none of the examples work with the ESP dev board.
Can you recommend any other IDE’s or RTC sketches that I could explore?
Thanks
Butch

Thanks for posting your resolution! And well done for figuring it out!
My choice of IDE is VSCode with the PlatformIO plugin enabled. Take your time with it, as it will reap untold rewards with your productivity, and help you make more complex projects with varying chips, as time goes on. It’s my go-to IDE now. Arduino IDE is great too, so if it works for you, don’t change. But do invest bursts of time experimenting with VS Code, especially if you’re playing with more than one board and more than one architecture.
I’m sure you’re already doing this, so for the benefit of others in different positions to you, please check out YouTube and blog posts to help you learn. I’m not an expert, yet I’ve been working professionally for many many years with software in various languages and platforms. It’s impossible to stop learning new things. There are more ways to learn now than there has ever been. There are also many opinions too. Everyone has an opinion. Don’t be blinded by one expert’s perspective or experience. Form your own opinion. and be open to changing it, if it makes you a better person, and then change it again, even if it goes against what you’ve learned. Eventually you’ll learn that it’s okay to change your mind!
