Please help me. How can fix this:
”this error originates from pyserial. it is likely not a problem with esptool, but with the hardware connection or drivers.”
I use esp32cam with esp32cam-mb

Following up on my previous post, I found my issue. I was looking at “Library Manager” and not “Boards Manager”. Under Boards Manager, I did indeed find the esp32 board, and I’m currently installing it.
Thanks for the tutorial!

Hi.
The wifi library for the ESP32 is simply WiFi.h

For what it’s worth, I use the boot button on some of my ESP32’s, but I use the added capacitor on boards that are built into things where the boot button might be hard to access.

When I use the boot button, I wait for the dots, and then hold the button until I see that its loading the sketch. Not sure if I have to hold it that long, but that’s what I do, and it works for me.

The alternative is a 10uF capacitor between the GND pin and the EN pin. With that, you can skip the boot button. But I realize I don’t have to tell you this Sara. Just bringing it up for the wider audience.

Press the BOOT button when you start seeing the dots in the debugging window.

In reply to Randy Constan. I don't know if this helps, but I've compiled and loaded ESP32 sketches from my 64 bit Windows & laptop for a long time. I've used the 1.8x arduino IDE and later. For what it's worth, mine is an ancient (like 10 years old) Lenovo T430. You can get them on Ebay these days for next to nothing.
