Please have a look at <a href="https://devzone.nordicsemi.com/b/blog/posts/bluetooth-smart-and-the-nordics-softdevices-part-1">this blog post</a> for details about how scan interval and scan window relates to advertising.&nbsp;SCAN_INTERVAL and&nbsp;SCAN_WINDOW are defined close to the top of main.c in the ble_central examples in the SDK.</li> <li>Lower the advertising interval, to increase the chance of any of the packets being received by the scanner.</li> </ul> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
