Many BME280 sensors in same i2c line

Post by mathamatias »

Hello,

I did not find any answers how to set i2c address of the sensor. I have 2 bme280 sensors in same i2c line (0x76 & 0x77).
How can i read both of them?

Thanks for the help in advance :)

they can be both seen by i2cdetect.

Hello,
Did you manage to solve the issue?
I'm confronting with the same problem. I want to connect 3 bme 280 sensors on I2C‐0 and I2C-1 of raspi 3 A+ board.
Is this feasible?
