Hello Alessandro10,
No, it should work in bread board as well.
Here is my two suggestions. ( I highly recommend first one)
1) Please migrate BMA400 API and use our example - activity change. Then, you can check where you have some issue.
https://github.com/BoschSensortec/BMA400-API/tree/master/examples/activity_change
2) Capture i2c or spi interface, then read all register you write. Then you can figure it out the data is really written in target registers.
Thanks,
