UWB Beacons Nearby Interactions API

Hello, I bought 2 Dev Kits of UWB Beacons, you have said that it is compatible with U1 and Nearby Interactions. Have you some examples on how can I use NINearbyAccessoryConfiguration to start communication with estimate USB Beacons? We want to use Nearby Interactions with ARKit to create our app experience. Is there a good documentation about the USB Estimote SDK? I have downloaded the sdk, but when I debug I am not getting the Directions Vector by your SDK.

These beacons will have habilitation to trigger another hardware by presence of nearby interactions, I saw that when the user get close to beacon they start to blink, it will be awesome if we can send signals to other devices.
