Hello sorry, I have the same error but I comment what you say and I use ESP32 Wrover Module but it tells me an error of compiling a card, I do not know what to do thanks.

In order to support BME280, I will use Adafruit_BME280_Library, but this library conflicts with and enters Adafruit_BME280_Library In Adafruit_BME280_Library change --> 29 lines comment #include , BME280 this library does not use this header file, so comment out and no problem

[collote69]

e commented #include but it gives me these errors I do not know what I do wrong

I'm sorry I do not know much about this

@collote69 Please replace your existing deletion with me. Adafruit_BME280_Library

[collote69]

Sorry I just did what you tell me I'm replacing the libraries and I'm testing with arduino in ubuntu now the error is:

@collote69 Have you replaced it with the library I provided?

I see the error message or the previous error. According to your error message, this library location should be at /home/comodo/Documentos/Arduino/libraries/Adafruit_BME280_Library/Adafruit_BME280.h

Jump to line 29, as shown below, close the header file, and then recompile.

[collote69]

if I replaced the library that I had provided and I just commented on line 29 of how the image shows me and now this comes out:

Hello, I did the last thing you said and uncomment #include "Adafruit_BME280.h" line 29 of the Adafruit_BME280.cpp library file and it works thanks so much and sorry for the inconvenience
