How to use channel sounding and direction finding on nRF54L15 at the same time?

[AllenDev]

Hi, 

I am currently using nRF54L15DK for Channel sounding development.

however, I would also like to add direction finding function, I know that there is no direction finding related example for nRF54L15DK yet, I would like to know if this function will be added in the future?

In addition, here is the information I found in Bluetooth official website:
www.bluetooth.com/.../

In it, it is mentioned that
Q: Can Bluetooth Channel Sounding be used in conjunction with other Bluetooth location features such as Bluetooth RSSI and Bluetooth Direction Finding?

A: Yes, Bluetooth Channel Sounding can be used in conjunction with other Bluetooth location features, including RSSI and Direction Finding. For example, we know of upcoming solutions that plan to use a combination of Bluetooth RSSI and Bluetooth Channel Sounding, where RSSI will be used to determine presence, distance, and heading when devices are far apart, and Bluetooth Channel Sounding will be used to improve accuracy when two devices are in close proximity to each other. be used to improve accuracy.

Due to the conflict of KCONFIG related settings, it is not possible to run both at the same time. I would like to know if I can use Channel sounding and direction finding at the same time in the future.

Thank you!

Hi,

Channel sounding is currently not supported in the SDK. Regarding support for this and direction finding for nRF54 series, plese contact the nordig sales representative for your region. (You can send me a direct message if you do not have the contact information).

Hi Einar,

Currently NCS v2.8.0 has added channel sounding function.

There is a sample code for it.

What I want to know is whether channel sounding can be enabled at the same time with direction finding.

As far as I know, it can't be turned on at the same time. Is there any plan to run both functions at the same time in the future?

Thanks!

Hi,

You are right that there is channel sounding samples in the SDK. The samples work but are experimental. You need to replace the algorithm with  your own (which is far from trivial) if you want to use this now and get acceptable results, or wait until we get support for it (for which I cannot share a timeline).

Regarding direction finding, that is not supported on the nRF54L15.

Hi Einar,

I found that more accurate algorithms for RTT and PBR are supported by Distance Measurement in nrflib.

However, it is only available for nRF52 and nRF53 devices.

Will nRF54 be supported in the future?

Thank you!

Hi,

Please contact sales regarding potential support for distance measurement on the nRF54L15, as I cannot comment on potential future features.
