There is the config LOG_ENABLE_FANCY_OUTPUT_FORMATTING which changes the zephyr logger to use a different format function that appears to support printing floats. If you just need the logger to print floats that is probably a more efficient than building in what sprintf needs to support floats.

I worked it around by unsing a sprintf

Hi Luca,

NCS v1.3.0 is using an updated Zephyr version:

See release notes
Floating Point Services

FLOAT and FP_SHARING Kconfig options have been renamed to FPU and FPU_SHARING, respectively.

So if you add CONFIG_FPU=y in prj.conf then it should work.
