I did recieve a new BME280 from china.
My sketch is still not working, so i expect it is not the BMW280 itself.
Does soembody nows a working sketch for BME280?
I'm using the adafruit BME280 library and the next programm:
Code: Select all// Do not remove the include below
#include "BME_test.h"
#include <Adafruit_BME280.h>
/***************************************************************************
This is a library for the BME280 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME280 Breakout
----> http://www.adafruit.com/products/2650
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface.

Serial.println(" m");
Serial.print("Humidity = ");
Serial.print(bme.readHumidity());
Serial.println(" %");
Serial.println();
delay(2000);
} SCL is connect to pin 2 (D1, GPI05)
SCA is connected to pin 3(D2, GPI04)
The error is That the BME is not found
I did use BMP180 before. These did work fine.
Please advise
