Channel Sounding - Speed and Multiple Devices

[MatthewP]

Hi,

We are evaluating BLE Channel Sounding for indoor localization of small mobile robots. We need 2D localization within the room, so we would need to measure the distance to multiple anchors.

We have some basic questions about this:

• How fast can a single distance measurement be performed? I've seen numbers in the range of 100ms?
• Is it possible to be paired with multiple anchors and perform BLE CS sequentially without having to establish a new connection each time?
• When can we expect an update of the SDK with CS support?

Thank you very much for your response.

BR, Matthew

Are you testing between with two nRF54L15-DKs using nRFConnect SDK 2.8.0?

Sorry, my question wasn't clear in that regard and it seems I have missed the support for CS in the release notes for 2.8.0.

So at the moment we aren't testing with DKs at all yet. We wanted to know whether it was even worth trying it out, depending on potential limitations from my first two questions.

In essence we would like to know how fast the positioning can run (in PBR mode for higher accuracy) and whether we can perform the ranging quickly with multiple connected anchors.
