https://devzone.nordicsemi.com/f/nordic-q-a/56908/how-to-improve-beacon-scan-efficiencyHello, I&#39;m currently developing BLE_SCANNER(GATEWAY) for asset tracking or management. My scan environment is, [Our device -- same UUID] The number of our beacons is 100. Each of beacons has an interval of 1000 ms (1 second) The BLE_SCANNERen-USTelligent Community 13Fri, 07 Feb 2020 11:50:37 GMThttps://devzone.nordicsemi.com/thread/233248?ContentTypeID=1Fri, 07 Feb 2020 11:50:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d0e7feca-4912-4122-871e-512f13ced8d7Marjeris Romero<p>Hi,</p> <p>If the point is to scan as many advertising packets as possible then there is no problem to set the scan window to 100%. The only problem with having the scanning window set to 100% is that you will not be able to perform other roles, you can only scan the whole time.</p> <p>Best regards,</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/232437?ContentTypeID=1Tue, 04 Feb 2020 02:21:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:70449c66-9475-4bbc-8ef6-c47b137e4da3leejh<p>Hello, msromero.<br /><br /></p> <p>If scan window increase to 100%, is there no problem?</p> <p>I heard that it was best to set the scan interval and scan window to 50%. Why didn&#39;t set it to 50% and load or problems when I set it to 100%?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/230851?ContentTypeID=1Fri, 24 Jan 2020 12:46:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7b3332a2-fdb3-4a3d-8258-242ee466b5e9Marjeris Romero<p>Hi,</p> <p>1. There is no option to filter by Manufacturer UUID when using nrf_ble_scan_filter_set(). I don&#39;t see this would have had any improvement in speed anyways as the event will still occur, and filtering is done inside the application.</p> <p>2. Increasing the scan window to 100% (scan window == scan interval) will help. The more beacons you have, the longer you have to scan to capture all of them.</p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
