When I checked the NearbyInteraction Accessory Protocol Specification, the sequence diagram in Section 2.4 stated (1) Establish a data link (ieBLE, LAN, Cloud, or other). However, in the sample code, there is no communication method setting for establishing the data link. Since it is described in the specification, it means that there is an arbitrary establishment method but the implementation method has not been released yet, or it is necessary to contact Apple at the time of product development and request disclosure of the specification. Please tell me who knows.

Can I modify the NearbyInteraction sample code on the Apple developer site (link below) for use in PoCs and final products? (As a premise, UWB chipset is supplied from UWB chipset manufacture who already or will have their chipset complete certification by Apple) And are there any restrictions on its use? https://developer.apple.com/documentation/nearbyinteraction/implementing_spatial_interactions_with_third-party_accessories
