Error at reading values frome BME280 #15

Closed chimcen closed 5 years ago

chimcen commented 5 years ago

Hi,

i've used your code before and it worked. I used it with an Wemos NodeMCU Mini D1 and a BME280 1.8-5V Breakoutboard (purple board with only 4 wire outputs - VCC,GND,SDA,SCL).

Today i've bought new of them, but received a BME280 1.71-3.6V Breakoutboard (purple board with 6 wire outputs - VCC,GND,SDA,SCL,CSB,SDD).

I've connected them as the "old" one - SDA=D6, SDL=D5, GND and VCC=3.3V. I#ve also loaded the same firmware and the same config from the old one to the new one.

The board is connecting my WiFi and starts up a web server. When i'd like to check the value readings in browser i'm only getting a read error:

Sometimes it errors out on the first or second try. Does it stable out?

No, the result is always the same. Figured out that my supplier send me a sensor module BMP280 instead of BME280 - this could be the reason, because BMP280 doesn't provide humidity.

When i'm receiving the real BME280 i'll report the changes...

NorthernMan54 commented 5 years ago

Okay

chimcen commented 5 years ago

As previously assumed - the error was because of using a BMP280 instead of a BME280.
