https://devzone.nordicsemi.com/f/nordic-q-a/122436/channel-sounding-result-quality-in-ncsHi, Is it possible in BLE channel sounding in ncs 3.0.1 to get some information about the quality of the distance measurement for each method? We have three ways to get the result, but I do not know how to combine them into one value. Maybe it woulden-USTelligent Community 13Tue, 24 Jun 2025 11:51:49 GMThttps://devzone.nordicsemi.com/thread/540317?ContentTypeID=1Tue, 24 Jun 2025 11:51:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b9b4a31-c102-4e27-9814-681422e54a6aEdvin<p>Hello,</p> <p>As you said, there are 3 different types of measurements. Round trip time, Phase based and ifft (inverse fast fourier transformation).&nbsp;</p> <p>The latter, IFFT typically gives the best performance accross all distances.&nbsp;</p> <p>A kalman filter would be possible, but that is outside of what we provide. And it would depend on some way of movement, and position estimates based on these movements. This is something you would have to implement in your application.</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
