Arduino ide configuration for ESP32C3 with LCD board

[brebisson]

Hello,

I am using one of the ESP32C3 based boards with the build in 0.42" OLED display...
( https://fr.aliexpress.com/item/1005007448048350.html )

But I am unable to get any wifi working. Using the Arduino WiFiClient example, I am able to successfully connect using a "ESP32C3 super mini board" (a board without the LCD), but if I try the same program on the board with the LCD, it does not work...

Does anyone have any idea what I might be missing?

Thanks,
Cyrille

Please check if there is a pin conflict in your code. I mean, check if any pin used by the LCD board is dedicated to wifi communication.

Hello,

Which pins are used by the Wifi?

At this point in time, I am using the Arduino Wifi example which does not interract with any HW (other than Wifi), so if there is a conflict, it is not due to me

Note that the exact same code, compiled with the exact same options, when sent to a ESP32C3 super mini board does work...

So I have no clue where to look...

Try running the WiFiScan example with core debug level set to verbose. If you aren't seeing any WiFi networks in the scan, then you probably have an interference/power issue.
