I work for ChannelSounding on nRF54L15.(NCS3.0.1)
I measured the distance using two nRF54L15-DKs.
The actual distance was 3m.
The average measurement result is shown below.
Zephyr ChannelSounding Sample(connected_cs) Result:
phase_slope(average): 3.826121886
RTT(avarage): 6.000941807
NCS ChannelSounding Sample(channel_sounding_ras) Result:
IFFT(average): 2.876786939
phase_slope(average): 5.269290868
RTT(avarage): 5.43838964
In the NCS calculation method, the phase_slope value seems to be larger than the Zephyr version.
Why is the NCS version less accurate?
