Hi,
I have this ESP32 module:
ESP32 Module
I followed this tutorial:
Getting started with ESP32 board
When I connect the board to my computer, no LED turns on, but the 5v, 3.3v and GND pins seem to work. I uploaded the blink sketch, and it didn't work. After that, I tried uploading other sketches and I've been getting this error:
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
I tried holding the boot button while uploading, as many have suggested, but it hasn't helped.
Any suggestions on what to try next?
Open the Arduino Ide, with the ESP32 disconnected (Windows). View the available com ports and write them down. Close that view the com port window, plug in your ESP32, and go look to see what's in the list now, has it changed from what you originally wrote down?
This is an important step, if the ESP32 is not claiming a comm port and is not showing up in the Arduino Ide then you cannot upload to it.
Let us know.

I checked. I checked in Device Manager as well. I'm trying to program through the correct port.
Make sure you are using the updated version of Arduino IDE and you have installed drivers correctly.
Is there any yellow limited sign on the Com Port, happens to me a lot and I have to reinstall the USB driver.
Turns out there was a problem with the board. Not sure what it was, but I got a new one, and did the same thing with it, and it works just fine.
