BMI270 Wiring with MCU for I2C Connection

[Sara_r]

Hi,

I'm using BMI270 Shuttle board for my project with I2C interface protocol. I have checked my code and seems everything is OK with that. I think something might be wrong with my hardware. Below figure describes my pin connections.  The first figure is how I wire the boards. The second figure is from BMI270 datasheet that I'm refering to. The resistors here are both 3.3k Ohms. Also is this connection correct for I2C protocol of BMI270 with address of 0x68?

The HW connection looks OK from the schematic you given.  

Maybe you can try to provide some logic analyzer plotter to check further
