    Simply do what's written in the message - MCU settings:

      This topic's been covered several times, you might have to fight if it keeps pulling the wrong libraries, not a fan of CubeIDE

      Watch you have enough spaces separating parameters, and that compiler and linker accept them

      https://community.st.com/t5/stm32cubeide-mcus/how-to-use-float-in-printf/m-p/323872

      Also DON'T use 32-bit float's for global level lat/lon positioning, there aren't enough digits to carry the low order precision consistently or adequately. Use 64-bit doubles
