That is why the linker complains. Try to go over the settings for the library project and make sure it uses the same floating-point settings as the blinky example.</p> <p>HW floating-point unit (FPU) enabled:</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-32dcc82bad4d4397832d375a73e4b579/pastedimage1598268993797v1.png" alt=" " /></p><div style="clear:both;"></div>
