Hi
Make sure you have the Serial monitor closed and that you’ve selected the right port in Tools > Port.

In reply to UMAR.

Hi.
That probably means that you didn’t select the right COM port or it is being used by another program.

Hi, I just bought a new esp32 board (wemos d1 mini esp32) and I am getting this error ever since it arrived. I have another which i bought last year and I dont have any issue with that one. I tried reinstalling the USB serial driver, arduino (several times), and pressing the button while uploading but nothing solved it. Hope anyone could help.

I was looking for a tutorial like this, but …
Is it possible to install the esp32 and esp8266 boards without internet connection but with a file that you can download and put in the right file tree ?
It is because at work the connection do not pass for security reason. At home with the same laptop, no problem to install.

Perfect!,

Strangely though, despite a good hour googling for answers, I decided to uninstall Arduino IDE while also removing the Arduino folder in AppData. Once I reinstalled IDE and added the apt. URL’s for esp32 and esp8266 everything is running again. Then out of curiosity, I googled again to see if others had the same problem and your link was top of the page…confirming my actions as correct!

Thanks for providing clarification with your highly informative website.

I had a problem just starting my IDE and the solution was the same – delete the arduino15 file. So my problem was more general than just downloading board URLs

My issue was that every time I tried to start the IDE I got the message “Initialising Packages” that that’s as far as it got – it returned to the start up screen.

There were many suggestions on Internet including deleting file arduino15. Unfortunately I didn’t appreciate it was a hidden file so couldn’t find it (immediately) to delete.

Once I did find and delete arduino15 everything worked fine. As I was only using the UNO I will have to re-install any add ons.

Many thanks for this!
My compiles for ESP32 and 8266 are very very slow (10 mins sometimes).
I’ve stopped anti virus to try that.
It seems to take ages compile the same stuff every time, even if I make a 1 line change, surely the caching can take care of this.
