I tried that, nothing worked.
also in the Arduino IDE I can't select
port

I am guessing you are on Windows????

  • When you plug in your ESP32 to your PC, do you hear a sound? If not, try a different USB cable.
  • Does Windows say anything about installing drivers failed? You might need to manually install the drivers.
  • If you open the device manager of windows are there any USB devices listed (after you plugged in the ESP32) that have no drivers installed? Then you most likely need to manually install FTDI (USBtoSerial) drivers.
  • I needed to install separate drivers for the onboard USB of my ESP32. In my case it was for a CP2102 chip. You can find the drivers here: ESP32.net.
  • Did you try to use a different USB cable?

And last, some ESP32 boards need to be set manually into bootloader mode. On my board that would be pressing the RESET button and keep it hold, then press the USR button and keep it hold, then release the RESET button, then release the USR button. Might be different for your board.

Thank you,,,
The problem was the driver CP210x is missing
and the cable wasn't good, even though I tried 4 or 5 different cables and finally I got one working.

Also, if you working on a laptop, make sure it is on full performance and plugged in.

Holding down the "Boot" button on my ESP-WROOM-32 while the Arduino IDE download the program worked. After the download I had to push the "EN" button to run the program. It did NOT start on it's own.

Hey, anyone here? I have a similar issue but unlike this one, I can select my COM Port and the drivers are also up to date. However, what I am finding out of place is that in the COM Port list I am getting some 17 options for COM1 even though nothing else is connected to the laptop. Any ideas?

you can get those COM port options in Device Manager

Did you select the proper serial port & speed? perhaps lower the speed to 115 or 230kbps
or as mentioned above (depending on the version of the esp32 board) pushing the boot button during the ...---... sequence helps.

  1. Make sure you have a good cable
  2. Enter download mode manually by resetting the board while the boot button is pressed.

Hey guys. I was getting this error and my work around was changing the "Flash Mode" from "QIO" to "DIO".

Hello, i have a ESP32-WROOM-32 and your Tip was the Solution for me. unplug the Device, hold Boot button and plug device, further hold boot button and Upload Firmware.

One other solution I found today not mentioned above that might help others.

Insufficient power from the computers (Microsoft Surface Pro 6 in my case) USB port caused exactly the same issue, even though when plugging in directly, the device was fully recognised in device manager and showing up as COM3 in my case. I knew the cable was good as I was able to flash firmware from a desktop machine.

Resolved by using either an externally powered USB hub, or a Surface docking station which among other things is also an externally powered USB hub.

Note I also did upgrade the driver using the CP210x Universal Windows Driver from https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers as that was newer than the fresh install of Windows 10 (21H1) provided, but do not believe that was necessary at all.

My ESP32 board is an AITrip ESP32-WROOM32D. Arduino IDE settings are (reading the bottom right of the IDE) ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 40MHz, 4MB (32Mb), 115220, None on COM3.

Hope that helps someone 😄

I was using the wrong port as well! It stayed on "Connecting..." while compiling before the timeout error. It worked once I switched to the correct port.
