https://devzone.nordicsemi.com/f/nordic-q-a/82639/beacons-close-to-each-other-directed-ble-beacon-signal-possibleHello there, I&#39;m working on a &quot;handsfree&quot; audio guide for a museum application. Right now I&#39;m exploring BLE to trigger the audio files based on the received signal strength of Beacons. Unfortunately my application might ask for beacons being quite closeen-USTelligent Community 13Mon, 13 Dec 2021 09:57:25 GMThttps://devzone.nordicsemi.com/thread/343098?ContentTypeID=1Mon, 13 Dec 2021 09:57:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:176fa8e3-851f-4fbf-9094-4d2ff2d7b3bbKenneth<p>RSSI to detect distance is very inaccuate, so I am sligtly skeptical to any approach where you rely on RSSI to detect distance, though I do know there are solutions out there that seems to work, for instance ibeacon by Apple. If you want to test an approach with external antenna you can for instance just purhase an nRF52-DK, which can be used with external antenna.
