Be advised that centrals do not advertise, and peripherals may advertise as anonymous - so you are not guaranteed to find&nbsp;<em>all</em> BLE devices near you.<br /><br />In the case that I misunderstood&nbsp;you, you might instead be looking for the <a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE">nRF Sniffer tool</a>&nbsp;to be monitor surrounding BLE traffic.<br />This is a powerful tool to have available when developing BLE applications.<br /><br />Please let me know if this does not answer your question.<br /><br />Best regards,<br />Karl</span></p><div style="clear:both;"></div>
