Error with Wifi Kit 32

[DireccionCI]

I have this error at the moment that I compile my code, and I don´t know why this appear if I don't still use any LoRa project

I have the same issue.

[Frosty-STI]

Me too!! I can't find any documentation for resolving this anywhere.

[whitehat101]

I saw this error when using the "Heltec_ESP32 Dev-Boards" library version 2.0.1. I was able to downgrade to version 1.1.5 and my sketch compiled cleanly.

[Mr-HaleYa]

They had a bug, it should be fixed with this PR HelTecAutomation/Heltec_ESP32#133
You will have to download the repo and manually install it as a library to use the latest until they push a new version with the fix.

[valdt]

Bug remains even with PR ? Anyone els having problems ?

[DireccionCI]

Yes I can remain the problem with that and the other comment behind TSM people

[algspd]

Same here, using the lib from github

[algspd]

Solved, add to your boards manager URLS:
https://resource.heltec.cn/download/package_heltec_esp32_index.json

And install:
Heltec ESP32 Series Dev-boards

Then select the board, and it works.

https://docs.heltec.org/en/node/esp32/esp32_general_docs/quick_start.html#via-arduino-board-manager

Same issue here even with the above board manager installed.
Downgrading to 1.1.5 works, thanks for the tip @whitehat101

Hey, after a lot of research and digging into this issue here is what I did to be able to Build it:
