Hi,
started the project yesterday and use an ESP32 with BME280 from ARDAFRUIT. First the sensor was not recognized. Then I soldered the “adress change pad” on the back-side of the module. Now it works. Therfore I would recommend that the accepted I²C adresses for all modules will be listed in the documentation. Are they shown somewhere in the Arduino-sketch? Can I change them anywhere in the code?
Regards
Hardy

Hi Robert,
I had the same issue. Maybe a hint in the documentation might be useful ("... the address is 0x76 ...there should be no reason to change...").
P.S. Again a great project from you!

the addresses one would find in mydefines.h
ahhhh, thanks a lot!

This is in the PDF
The I2C address of the BME280 sensor is defined as 0x76 in the myDefines.h file as BME280_I2CADDR.
There should be no reason to change this.
But considering the number of pages in the PDF, not surprised it was not found
