It might help to figure out what caused the hardfault.&nbsp;</p> <p>There is a tutorial <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/an-introduction-to-error-handling-in-nrf5-projects">here </a>that might be useful to debug hardfault.&nbsp;</p> <p>If you tested with the default ANCS example do you see the issue ? How long it usually take to get to the hardfault error ?&nbsp;</p><div style="clear:both;"></div>
