I am a beginner with Arduino IDE and ESP32.
I’m using a WEMOS ESP32 LITE board with BME280 4 pins (SDA,SCL,GND and Vin) when I use an other script using wire statement, the BME works fine. With the current script however, the BME280 is not found…. How can I solve this?
Kind regards,
Hans

It seems like I did everything right. And in the port monitor it is like this.

ESP32 is constantly rebooting.

What ESP32 board are you using?
Which board are you selecting in Tools > Board?
