Hello @Federica Bossi,

I've Unico 9.17.0.0, firmware version is V3.65.5.

Looks like ST shipped me MKI172V1 with burned out LSM303AGR IC.
I've resoldered it from my board. Now it works!

Hi @Kaa ,

Welcome to ST Community!

I tried the same test and I don't have any error.

Which firmware are you using? Unico GUI?
