Bonjour,
J’ai un souci de connexion, j’arrive à me connecter et voir la page web.
Mais lorsque je ne l’appelle que plus tard j’ai souvent: The request timed out et je peut ressayer plusieurs fois mais rien ni fait.
La seul solution que j’ai trouvé, c’est de débranché l’alimentation et la rebranché. La page web est a nouveau accessible.
Qu’elle peut être la raison?
Je tourne en rond!
Merci d’avance
Daniel

In reply to Pat. I modify library everytime it has been updated and it works fine. Did you update since you modify ?

Hi.
You may have a “fake BME280”, that in fact is a BMP280.

Hi Sara!
I have the same problem as Manu. Scanner says 0x76 address works. So I too modified the adafruit_BME280.h file as Manu did. Unfortunately this did not work for me. Still getting “Could not find a valid BME280 sensor, check wiring!” errors. Any suggestions?
Thanks!
Pat

Hi Sara..I get this error.. ESP8266, ESP01, Arduino Nano sketch works fine. Any ideas…

Hi.
It seems you have a BMP280 and not a BME280.
The BMP280 sensor doesnt measure humidity.

hello,
how did you modify the lib
i wanna measure temperature, humidity and pressure so i used lib ….but i got this message in serial monitor : Could not find a valid BME280 sensor
i tried to scann i2c address ….it’s 0x76
when i use lib , it works (but i can just measure temperature and pressure.
i need t measure the 3 meteo parameters

Hi,
thanks for the coding examples – nice tutorial.
Setting the table width in html code to 90% will show the values and units in one row. Maybe 75% or something between will also work.

ESP8266 with BMP280
MEASUREMENT VALUE
Temp. Celsius 35.12 *C
Temp. Fahrenheit 95.22 *F
Pressure 991.12 hPa 29.27 inHg
Approx. Altitude 185.86 m 609.77 ft

I used a BMP280, modified the web page, no humidity with this sensor.
