The goal of the project is to be able to identify the proximity of beaconing devices in an area to a specific observer which then reports that device data such as name or some other identification back to a multilinken-USTelligent Community 13Tue, 06 Apr 2021 14:54:32 GMThttps://devzone.nordicsemi.com/thread/303241?ContentTypeID=1Tue, 06 Apr 2021 14:54:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2eb5f2af-6093-4c06-a354-21d60c549814tesc<p>Hi,</p> <p>Yes, for 128 bit UUIDs (aka vendor specific UUIDs) you must use sd_ble_uuid_vs_add() to add the &quot;base UUID&quot;, which is everything except for the 16 bits in byte 12 and 13 of the full 128 bit UUID.</p> <p>For more information, please have a look at <a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-services-a-beginners-tutorial">Bluetooth low energy Services, a beginner&#39;s tutorial</a>, and in particular the section named <em>Universally Unique ID (UUID)</em>. While the tutorial is updated only to SDK version 15, the concepts are identical for SDK 17.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/302862?ContentTypeID=1Thu, 01 Apr 2021 15:22:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c042b824-7a21-4507-8be5-3df5884f7a2fBenjaminHolmes<p>One quick edit I failed to copy over correctly. That should be SCAN_UUID_FILTER instead of SCAN_NAME_FILTER. I just copied it over wrong</p><div style="clear:both;"></div>
