Nearby Interaction (UWB) Background problem

Hi,

We try to geolocate with UWB signal an app in background with NXP UWB Kit. We use Nearby Interaction method in background

Apple documentation indicate to use this class: NINearbyAccessoryConfiguration

but we have this error when we try to create the session: NIERROR_ACCESSORY_PEER_DEVICE_UNAVAILABLE_FAILURE_REASON

any body can help us to use successfully this functionnality ?
