I moved your topic to a more appropriate forum category @hoanglong22.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

Hi @hoanglong22. This error might be caused by having the wrong port selected from the Tools > Port menu in Arduino IDE.

Please perform this experiment to verify that the port you have selected is your Arduino board:

1. Disconnect the USB cable of the Arduino board from your computer.
2. Select Tools > Port from the Arduino IDE menus.
3. Take note of the ports (if any) listed in the menu.
4. Close the Tools menu.
   The ports list is only updated when the Tools menu is re-opened, so this step is essential.
5. Connect the Arduino board to your computer with a USB cable.
6. Select Tools > Port from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.

If you saw a new port appear at the last step, select that port from the Tools > Port menu and try uploading again.

If this doesn't solve the problem, please reply here on this forum thread with the answers to the following questions:

• While following those instructions, did you see a port in the Tools > Port menu at step (6) that was not present at step (3)?
• If you did see a new port, was the upload successful after you selected that port?
