OpenThread and BLE channel sounding

[Eldar Firing]

Hi, 

We are considering using nRF54L15 / SDK3.1.1 -> as a wearable device that is part of a Thread network. We also need to do sporadic BLE connections and channel sounding measurements to the wearable device. The wearable will be a cs reflector. I see from the documentation https://docs.nordicsemi.com/bundle/ncs-3.0.0/page/nrfxlib/softdevice_controller/doc/channel_sounding.html that radio co-existence is not supported. Does that mean we cannot combine Thread with channel sounding at all, or is it just not verified? Are there any tweeks possible to achieve this ? 

Regards,

Eldar

Hi,

If Thread role is Sleepy End Device, the radio should be available for CS reflector when it is not used by Thread stack.

The link below is an example project based on NCS v3.1.0 that combines Matter-over-Thread and CS initiator:
https://github.com/lats1980/matter_template/tree/matter-occupancy-initiator-1.0

With a loose polling interval, the CS reflector should have enough radio time slot to interact with initiator. I would recommend intigrate OpenThread CLI sample into CS reflector sample as a start point.

Best Regards,

Larry
