![]() If everything went as expected, there would be a “Done uploading” message, and the onboard LED of the ESP32 board will start blinking.Many times it is necessary to produce a programmable frequency output or implement a frequency counter for various uses. ![]() When you see the message as shown in the figure below, release the BOOT button.Try to Press and hold the BOOT button on the ESP32 board during the complete upload process. Important: If there is an error while uploading the program then you may see this error message “ A fatal error occurred: Failed to connect to ESP32: Timed out… Connecting…”.Make sure that you have selected the correct COM port and board version.Just remember some key points during the upload process: Type a simple onboard LED blinking code(given below) and upload it to the board. Step 8: Now you are ready to upload your code/sketches to the ESP32 board. And if the issue persists, you need to install the Arduino board driver follow these steps as shown in this link. Note: If you don’t see any port option there, try inserting the board into another USB port. So go to Tools>Port, and select the port (like COM4 as shown in the figure given below). Step 7: Now after selection of the correct board version we have to select the port to which the ESP32 board is connected. Click on this option and select the version of your ESP32 board (I have selected the ESP32 dev module from the list). Step 6: Now after the installation, in the Tools> Board menu a new option should appear “ESP32 Arduino” as shown in the figure below. Once the installation is finished, close the Board Manager dialog box. Now select and click on the install button for “ESP32 by Espressif systems”, wait for the installation to be download and installation to be complete. Step 5: In the board manager dialog box, click on the search bar. The board manager dialog box will appear in front of you. Step 4: Now open board manager from Tools>Board Menu as shown in the figure below. Note: In case there are already some links present in the Additional Board Manager URL, you can add new URLs by using a comma to separate them. Step 3: Paste the URL: “ ” into the “ Additional Board Manager URLs” box as shown in the figure below. Then go to File>Preference from the top menu You can download the software for Windows, Mac, and Linux 32 bit, 64 bit, Arm, Arm64. Step 1: Download the Arduino IDE from the official website of Arduino.
