We highly recommend to use some kind of low pass filtering as well. A 3 stage median filter removes most outliers with minimum latency impact.

Hi Simon

According to your suggestion, I will re-test and use DK at both ends.

If you have the test data, you can also provide it to me.

Best regards,

Kenlove

Are you using an nRF52840 DK on both sides of the test? If not, what are you using on the other side for testing?

In order to get better and more stable results, you could enable the High-precision calculation, that does a more compute-intensive high-precision distance calculation by setting the CONFIG_DM_HIGH_PRECISION_CALC Kconfig option. High-precision calculation has an impact on MCPD ranging mode only. It also seems like you could do with the calibration explained in the section below the high-precision, as there is an ~70 cm offset in most of your measurements.

Best regards,

Simon
