Description

With 2.0.14 installed since few month with preferece :
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
note: it's same thing with preference :
https://espressif.github.io/arduino-esp32/package_esp32_index.json
question : is it possible to préserve compatibility with old version (legacy) ?
2.0.14 is not displayed, so it's imposible to uninstall it, and if i want to stay in 2.0.14, the core is not displayed on available board.

it does not show because it's already installed. I suggest you go to 2.0.15 though. it's the same as 2.0.14 with some fixes

[PM04290]

All ESP32 have desappeared, and i can't remove 2.0.14 to install 2.0.15

[CemDemirkartal]

I need 2.0.14 version too, Is there a manual way to install it?

2.0.15 has bugs, Serial 1 and Serial 2 do not work on nodemcu esp32s v1.1 module
It was working well on 2.0.14 version, now working on 2.0.11 version which available previous version to install.

[me-no-dev]

seems to me you forgot to load the proper JSON, so you see only the versions that are released by Arduino.cc

[CemDemirkartal]

With https://espressif.github.io/arduino-esp32/package_esp32_index.json

"2.0.15" , "2.0.11" and "2.0.10" versions are listed

[lyusupov]

@me-no-dev
both 'stable' and 'dev' JSON files are truncated:

• "2.0.15" is the only listed in the 'stable' one: https://espressif.github.io/arduino-esp32/package_esp32_index.json
• "3.0.0-rc1" is the only listed in the 'dev' file: https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json

references to all previous versions are missing...

[me-no-dev]

holly cow... something really went crazy with those jsons. I guess we have work to do for next release

[me-no-dev]

I have updated both JSONs. Can you please confirm that you see the older versions on the stable json and alpha3 on the dev json

Your update has positive effect !

Thank you so much!

@lyusupov I have no idea why it failed. Script has worked for years without issues and it worked for 2.0.14, yet we have not changed it a bit in it since.
Dev channel also failed when we started releasing alphas, but nobody noticed until now.

Thanks for your investigation. It really pinpointed the issue. Others saying that they see other versions made no sense, except if they were looking at the Arduino.cc released versions, which were exactly those.

Anyway, we should be good for now and we will fix them for future releases

Had the same issue yesterday where only .11 and .15 shows up and had errors on Serial2. But today, almost all versions showed up and I can now revert to .14 instead of .11 only.
