Chrome Duino Uploading to Compiler Server Stuck

The ESP32 has a few common problems, particularly when you are trying to upload new sketches or install the ESP32 improver on the Arduino IDE. This guide is defended to the ESP32 when programmed with Arduino IDE. Here, we provide a compilation with some of the most mutual problems with the ESP32 and how to ready them.

Of import: brand sure you have the latest Arduino IDE installed. Using a different Arduino IDE version might cause other unexpected problems and errors.

Note: Espressif establish some silicon pattern errors in the ESP32 which might be responsible for some unexplained errors/behavior. The errors are detailed in the post-obit document:

• https://espressif.com/sites/default/files/documentation/eco_and_workarounds_for_bugs_in_esp32_en.pdf

Of item note are three.i (relating to power upward and deep sleep wake-upward) and iii.iv (relating to non restarting on brownout). The old v0 and v1 fries were used in modules labelled ESP32-WROOM-32. The errors are fixed in modules ESP32-WROOM-32E and any other ESP32 designations ending in E.
See https://www.espressif.com/en/products/modules for full details. And so, to avoid getting bug with your ESP32, we recommend searching for the ones labeled ESP32-WROOM-32E.

1. How do I install the ESP32 addition for the Arduino IDE?

There's an add-on for the Arduino IDE that allows y'all to program the ESP32 using the Arduino IDE and its programming linguistic communication. Follow one of the adjacent Units to fix your Arduino IDE to work with the ESP32 in your operating organization:

• Windows instructions – ESP32 Lath in Arduino IDE
• Mac and Linux instructions – ESP32 Lath in Arduino IDE

2. I can't run into the ESP32 boards in the Arduino IDE Tools menu (Windows PC)

If yous still don't see the boards in the Arduino IDE, brand sure yous click on the small arrow (highlighted in the figure beneath) to curlicue all the mode down through the boards:

If at this moment you can't find your ESP32 board name, we recommend repeating the installation process from scratch.

• Windows instructions – ESP32 Board in Arduino IDE
• Mac and Linux instructions – ESP32 Board in Arduino IDE

three. C:\\Users\\ User\\Documents \\Arduino\\ hardware\\ espressif\\ esp32/tools /xtensa-esp32-elf /bin/ xtensa-esp32- elf-g++": file does not be

Afterward installing the ESP32 add together-on, if y'all open the Arduino IDE and it fails to compile code to your ESP32 lath, nosotros recommend re-running the Arduino IDE ESP32 add-on intallation.

Notation: Windows PCs frequently accept multiple Arduino IDE versions installed (portable and local installations). Make sure you are running the Arduino IDE where you lot installed the ESP32 improver.

4. A fatal error occurred: "Failed to connect to ESP32: Timed out… Connecting…"

When you try to upload a new sketch to your ESP32 and it fails to connect to your board, information technology means that your ESP32 is non in flashing/uploading mode.

Having the right lath name and COM por selected, follow these steps:

• Hold-downwards the "Boot" button in your ESP32 lath

• Printing the "Upload" button in the Arduino IDE to upload a new sketch:

• After you see the  "Connecting…." message in your Arduino IDE, release the finger from the "Kicking" button:

• Subsequently that, you should run across the "Done uploading" bulletin

That'southward information technology. Your ESP32 should accept the new sketch running. With those boards/with that setup, after uploading a new sketch, printing the "ENABLE" button to restart the ESP32 and run the new uploaded sketch.

You'll too accept to echo that button sequence every time you lot desire to upload a new sketch. Just if yous want to solve this issue in one case for all without the need to printing the BOOT push button, follow the suggestions in the next guide:

• [SOLVED] Failed to connect to ESP32: Timed out waiting for packet header

To exist honest we're not sure why that happens with the newer boards. We don't take any ESP32 board with that behavior. We think at that place might be something dissimilar with your specific lath or the Arduino IDE fails to send the right control sequence to put the ESP32 automatically in flashing/uploading style.

five. Error compiling WiFiScan sketch

If y'all attempt to upload the ESP32 WiFiScan.ino sketch provided in the ESP32 Getting Started guide:

And it fails to compile with a similar error bulletin:

In function 'void setup()': ScanNetworks:52: error: 'form WiFiClass' has no member named 'firmwareVersion' String fv = WiFi.firmwareVersion();

It looks similar your Arduino IDE is compiling the WiFi library for the Arduino board (instead of using the ESP32 WiFi library).

Note: you'll probably never use any WiFi shield with your Arduino lath, right? If you don't use information technology, you demand to remove that binder/those folders from your Arduino IDE (move it to your desktop, for case).

The WiFi library is located, in a like path:

C:\Users\ruisantos\Downloads\arduino-1.8.seven-windows\arduino-1.8.7\libraries\WiFi        

And/or at:

C:\Users\ruisantos\Documents\Arduino\libraries\libraries\WiFi        

After removing the unabridged WiFi library folder from i location or both locations, restart your Arduino IDE and endeavor to compile the code once again.

If you plug your ESP32 lath to your computer, but you tin't find the ESP32 Port available in your Arduino IDE (it's grayed out):

It might exist ane of these 2 problems: i. USB drivers missing or 2. USB cable without data wires.

1. If you lot don't come across your ESP's COM port bachelor, this often means you don't have the USB drivers installed. Take a closer look at the chip adjacent to the voltage regulator on board and bank check its name.

The ESP32 DEVKIT V1 DOIT board uses theCP2102 chip.

Go to Google and search for your particular chip to find the drivers and install them in your operating system.

You tin download the CP2102 drivers on the Silicon Labs website.

After they are installed, restart the Arduino IDE and y'all should run into the COM port in the Tools menu.

2. If you take the drivers installed, merely you can't see your device, double-bank check that you're using a USB cable with data wires.

USB cables from powerbanks frequently don't take data wires (they are accuse only). So, your calculator will never plant a serial advice with your ESP32. Using a a proper USB cablevision should solve your trouble.

7. Arduino IDE Serial Monitor "doesn't work"

If the ESP32 is but printing weird text or gibberish messages in your Arduino IDE Serial Monitor, make sure yous have the right COM port selected and fix the right baud rate as shown below. In most examples, nosotros're using 115200 baud rate.

8. Error: "Brownout detector was triggered"

When you open up your Arduino IDE Series monitor and the error message "Brownout detector was triggered" is constantly being printed over and over again. Information technology means that there's some sort of hardware problem.

It's oftentimes related to one of the following issues:

• Poor quality USB cablevision;
• USB cablevision is too long;
• Board with some defect (bad solder joints);
• Bad reckoner USB port;
• Or not enough ability provided by the computer USB port.

Solution: try a different shorter USB cablevision (with data wires), try a dissimilar figurer USB port or utilize a USB hub with an external power supply.

ix. I tin can't make the ESP32 improver work with Arduino IDE

If y'all've followed all the troubleshooting tips and the ESP32 addition doesn't work with the Arduino IDE, we recommend experimenting programming the ESP32 with Cantlet text editor and PlatformIO IDE. Follow this post: Cantlet text editor with PlatformIO IDE to plan the ESP32.
