Hi,

Seems your Adafruit BME280 module isn't configured to use the default address which is 0x76
Please check Adafruit documentation, so see how to change it from 0x77 to 0x76

EDIT

From Adafruit documentation:

By default, the i2c address is 0x77. If you add a jumper from SDO to GND, the address will change to 0x76.

Ok, I Will try to read the adafrut documentation in order to change the adress.  
I will keep you informed. 

thanks
