What SoftDevice are you using in this application?</p> <p>Seeing as the values are all 0, do you move the device at all? I would imagine an accelerometer would only output values other than 0 if in motion. Are you able to confirm which line is printing these values exactly? I didn&#39;t spot what could be wrong at the first glance at your code I&#39;m afraid.</p> <p>Best regards,</p> <p>SImon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/328537?ContentTypeID=1Wed, 08 Sep 2021 09:22:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c6226a74-65c0-4884-9cc9-5e1dfb2ec0bdrh.amine<p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/lis3dh.c">devzone.nordicsemi.com/.../lis3dh.c</a><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/lis3dh.h">devzone.nordicsemi.com/.../lis3dh.h</a><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/7380.main.c">devzone.nordicsemi.com/.../7380.main.c</a></p> <p></p> <p>please help me i just need some configuration in Lis3dh.c</p><div style="clear:both;"></div>
