The default behavior here is to reset the chip. You should debug the application to see where the error is reported, see <a href="https://devzone.nordicsemi.com/f/nordic-q-a/10729/my-device-is-freezing-and-restarting">this thread</a> for more information. <a href="https://www.youtube.com/watch?v=uP8RYgYGRvI&amp;list=PLx_tBuQ_KSqGHmzdEL2GWEOeix-S5rgTV&amp;index=7">This video tutorial</a> may also be useful if you are using SES.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
