Hello,

I have tried compiling for "ESP32 Dev Module" and it compiles successfully on Arduino IDE for the basic_demo.ino example. Could you please check again?

PRiD357 commented 2 years ago

Hello,

I have tried it again after reinstalling both the library and esp32 stuff. Unfortunatly i still get the same error when compiling for "ESP32 Dev Module".

Hello,

Did you try the basic_demo.ino example?

Also, have you added ESP32 board URL to File > Preferences as https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json ?

I tried again, and still it compiles fine for me.

Hello,

I tried with the example given etc. I tried to compile the example with version 2.0.2 of the board installed and esp32 dev module selected and still had the same error.

Hello,

there aperently was an issue with the arduino library manager. I installed the lib directly from zip and it works now. I am sorry if i have coused any incovenience.

Thanks
