Description

I am trying to install Arduino Core for ESP32 in Arduino IDE 2.0.4 on Windows 11 using additional URL method described in official documentation.

https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html

In this method, JSON url is given as below:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

I pasted this link in File>Preferences>Additional URLs

When the board index updates, It shows error saying "Some index Can't be updated" . The same error is repeated when I try to install ESP32 core using arduino-cli.

One thing I tried is to install other core to verify my setup. I successfully installed RP2040 core using JSON URL method. So I can say my steps are right.

Please let me know solution to this trivial issue.

Could you maybe have the json links added in a wrong way? I think one per line is how it should be. People here definitely do not have issues installing from Board Manager

Yes, I indeed suspected that. So, I removed all other URLs and only kept ESP32 JSON Link. Still The issue persists.

Just another observation, I have other two URLs, RP2040 and STM32.

RP2040 works. When I open JSON URL in browser, I get JSON in response.

STM32 and ESP32's JSON URLs doesn't give anything back when opened in browser.

Can you please try with the following link instead: https://espressif.github.io/arduino-esp32/package_esp32_index.json

Please report back the result

Hey, This link works very well! Thanks a lot!

Wonder why this link is not updated in official documentation!

[me-no-dev]

I wonder why you are having issues with the other one. In any case, we will update the docs. Both links point to the same file :)

Well, I am facing similar issue for stm32duino Arduino core. So, there might be issue on github side. Thanks again!
