The Nearby Interaction Accessory Protocol Specification defines a lightweight, transport-agnostic, and application-level protocol that facilitates configuring, starting, and maintaining an Ultra Wideband (UWB) ranging session between an accessory and an Apple device. **An app on a supported UWBenabled Apple device is required in order to allow users to set up, configure, and use their accessories. Does this app need us to develop? Can I use the Find My app to add my accessories and use the UWB high-precision lookup feature?
