Hi Nordic team,
I'm currently working on a real-time distance measurement project using channel sounding with the nRF54L15 DKs. I’ve been using the channel_sounding_ras_initiator and channel_sounding_ras_reflector samples from your official GitHub repository, and I’ve managed to get the system running successfully.
However, the performance I’m getting in terms of distance accuracy and responsiveness is noticeably worse than what’s shown in your YouTube demo (https://www.youtube.com/watch?v=dbQKqXN80ms). In your video, the distance tracking appears smooth and accurate, even when the devices are in motion.
In my case, the measurements are much more noisy, and there’s a significant delay (sometimes several seconds) between physical movement and updated distance readings. I’ve only made minor modifications to the sample code—such as increasing buffer sizes and applying a median filter to reduce noise.
My questions are:
-
Is the code used in the YouTube demo exactly the same as the
channel_sounding_ras_initiatorandchannel_sounding_ras_reflectorsamples, or was it modified for the demo? -
Are there specific hardware requirements or environmental conditions (e.g., antenna placement, orientation, shielding) that are crucial for achieving the best performance?
-
Is any calibration or parameter tuning needed beyond what is included in the sample projects?
I’d really appreciate any tips or insights on how to get results closer to what you demonstrate in the video.
Thanks in advance,
Ibai
