Are there any sample codes for AOA/AOD of nRF54L15?

I saw in nrf connect sdk 2.9.1 that there was nRF54L15 sample code for Channel Sounding and nRF52833 DK sample code for Direction finding.

But now I want to implement the combination function of aoa and Channel Sounding in nRF54L15, so do you have the Direction finding example code suitable for nRF54L15?

Hello,

Yes, That is correct.

I saw this post and have a follow up question, as we have a similar application.

Does the nRF54L15 support adding CTE to the advertisement packet?

That way a nRF54L15 could be used in the moving device. The anchor could use a dual uC anchor, ie nRF54L15 (supporting channel sounding) and nRF52833 (supporting AoA) together with an antenna array.

In this configuration would it be possible to achieve both direction finding of the moving device and perform channel sounding when needed?

I've similar need of doing direction finding for moving objects, and performing channel sounding when needed.  Is this "dual uC anchor" the best approach? or is there other alternative that make it less complicated?

From my knowledge, Nordic unfortunately did not offer a solution for both channel sounding and direction finding when we were looking into it. I am not sure what the status is now.

I would recommend to open a private ticket or contact Nordic directly to get an updated answer.

Channel sounding is already supported on NCS 3.1.1, though Direction Finding (AoA/AoD) is not officially supported on the nRF54L15.

That said, it’s feasible to handle both on the same chip: I was able to emit extended CTE beacons with the nRF54L15 using NCS 3.1.1. Combining channel sounding and direction finding on a single nRF54L15 could potentially provide more precise positioning, reducing the need for a dual-MCU setup.
