Does NRF-5340DK or NRF-52840 supports LE Channel Sounding Feature .

[Abhinav152]

I want to use the boards  NRF-5340DK or NRF-52840 with the external host for the channel sounding feature. Can we use the feature on the mentioned board? If so, can you please provide the steps to enable the controller support on the board? It would be helpful if you could give the config flags that should be enabled for channel sounding.

No, Bluetooth Channel sounding is only supported with the nRF54l15 DK. Samples in the nRF Connect SDK.

For the nRF52/53 you can use NDT, available in the nRF Connect SDK.

Thanks for the prompt response. Can you please explain what is NDT?  I checked the samples for channel sounding. Can we use NRF53/52 with NDT for channel sounding?

NDT is Nordic Distance Toolbox, a Nordic proprietary ranging solution for the nRF52 and nRF53 series. You can check out the sample at https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/nrf_dm/README.html.

This is not Channel Sounding which is a Bluetooth standard which is only supported on the nRF54L15 DK but a Nordic Proprietary solution. It is quite different from Channel Sounding and will not work with Channel Sounding devices even if the physics enabling the ranging is very similar.

OKay Thnaks for clarification

Can you please mention the steps to use an external host with nrf54l15 to use the channel-sounding feature?
