https://devzone.nordicsemi.com/f/nordic-q-a/125850/openthread-and-ble-channel-soundingHi, We are considering using nRF54L15 / SDK3.1.1 -&gt; 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.
