When timeout is reached, the example will stop advertising and go to system off mode. You can then restart the device by pressing button 1 on the DK.</p> <p>If you change the define <code>APP_ADV_TIMEOUT_IN_SECONDS</code> from 180 to 0, the device should advertise without any timeout.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
