Arduino nano and sensor on a i2c

Hi, does someone knows how to read a arduino nano and an other i2c device like a sensor?
I'm able to do it but there is some interference.
I think the problem has to do with the Wire.onReceive() that you need for the arduino nano and multiple i2c addresses... It would be nice if someone knew how to do it properly ..

Thanks for you time

A: Is your I2C Bus Network Like this:?
1. Arduino UNO is a Master

2. Arduino NANO is an active Slave with I2C Bus address 0x08 (for example)

3. BME280 as temp and humidity sensor

B: Do you want to tell NANO to acquire data from BME280 and forward the same data to the Master when request goes from the Master?

C: Or something else; if so, please describe clearly.

Yes that's about right

Does that mean the Nano has to listen to multiple I2C addresses? The hardware doesn't support that.

Please explain what your problem is.

So please, describe your problem clearly!
