Status of Nordic Distance Library after release of BT Channel Sounding

[mkopp]

Dear Nordic Support Team,

Could you please provide more information on the current status of the Nordic Distance Library (https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/nrf_dm/README.html#nrf-dm)?

It has been labeled experimental for the longest time and I have been eagerly waiting for an update, especially with the release of BT channel sounding. I was hoping that Nordic would continue to develop this library. However now it seems that its being left behind as new samples have been introduced already in NCS3.0.0 for the nrf54 series.

What about nrf52/53 series? I have implemented this library into my custom application. It works okayish with ifft almost always being the best approximation (high precision calculation keeps returning 0, have never gotten that to work...). I understand that channel sounding is not supported for nrf52 series but are there any plans to continue to develop the distance measurement library for nrf 52/53 series?

Let me know if you have any ideas concerning the high prec calc not working, let me know what you need me to send, thanks!

Best regards,

Mickael

Hello Mickael,

The Nordic Distance Library is supporting the nRF52 and nRF53 series, and will be so going forward as these devices will not support Channel Sounding. The code used is still marked as experimental, but this is only as it will allow us to change the APIs if needed. The quality is the same as for non-experimental code. We do not have any plans to depricate this today, but for the time being, we are not adding any new features either. 

The nRF54 Series will be the supported devices for Channel Sounding, and we are adding features here. There are areas where the Nordic Distance Toolbox have advantages over Channel Sounding, and vice versa, so we will keep both going forward.

Best regards,

Edvin

Hi Edvin,

Thank you for your response and the info!

Did you see my comment about the high precision calculation? Do you have any ideas?

Best,

Mickael
