BME 280 ADAFRUIT SENSOR - NOT WORKING

Projects Programming
1

Hi everyone, I have just received 2 x BME280 sensors from Adafruit.

I am trying for some hours now but without luck to receive some data. I do not know what is going wrong. I am using the I2C bus and a Firebeetle board.

[not_found ... ption=true](not_found ...)

I have installed the BME280 v.1.0.10 library from Adafruit and I can read the I2C address (0x77) from the I2C scanner sketch of Arduino. I tested both sensors without lack.

Furthermore, I followed the tutorial provided by Adafruit...

https://learn.adafruit.com/adafruit-bme ... r-breakout

What I actually receive from the sensor is the "nan" value as shown from the picture below

This is the wiring

Also, I tested the sensor with an Arduino Uno. For some reason that I cannot understand the sketch cannot exit the begin() function of bme class.

I am intended to use the sensor with the firebeetle board, so at this stage, I want to resolve the problem with this board.

Any recommendations?

Thanks in advance

Try having connection of VIN-pin of BME280 with VCC-pin (not 3.3V). The sensor has a built-in 5V/3.3V regulator and 5V/3.3V/5V level sifters.

Still if not working, please post your codes.

I figured out the problem.. On of the jumper wires was broken >:( This is strange because during the I2C scanning it was working normally..
