#90503 Hello there,

I am new in arduino and this world of projects, I appreciated any feedback, I have been dealing with a problem trying to follow this project https://github.com/IU5HKU/MiniWXStation . version of the project bme_V08c.
My situation is the next one: I configured the ESP8266, I upload the sketch and also I connected the sensor BME280, however, When I tried to verify the lectures of the sensor I got this message:

But, this lecture is not correct, it looks like the sensor is not working. I bought 3 different sensors, I did test and all of them are showing the same lecture. I tested using another ESP8266 from a friend of mine and I found that all the sensors are in good condition, but I´m not sure what is happening between my ESP8266 and the BME280 . I currently using BMP280 and I´m not getting any lecture. I would like to get support on this problem in order to resolve this issue. Thanks a lot for the help in advance.

PD: I tried to make this project using the AMICA NODEMCU ESP8266 and the ESP8266 CH340 V3



I ran the I2C test and I got this:


Scanning...
No I2C devices found

I changed the wire cables and also I ran again another test, I got this:

Could not find a valid BMP280 sensor, check wiring!



I changed the sensor ( I bought 3) and none works, I bought another ESP8266 and I having the same behavior, I will appreciate any guidance or some light in order to resolve this problem.
