Can we broadcast light custom application data using ultra U1 technology without BT/Internet connectivity? I have UWB Ultra wideband integrated in my multiple iPhones using which I want to send/receive custom data (very low amount, possibly couple of integers with interval) between two iPhones without requiring any validation (connection establishment). The requirement is similar to broadcasting advertisement message of BT/WiFi. I wonder for UWB if it is possible or not. Any paper or article if feasible?

I would like to hear from you.

I am creating an IOS app using swift and was wondering if the Nearby Interaction framework (https://developer.apple.com/documentation/nearbyinteraction) could be used to locate and transfer files from one iPhone to another.

Hello, i want to know if an Iphone 11 with its U1 Chip for example is able to get angle information of another Iphone and in how many dimensions. I reckon more than 2D is not possible. An Iphone in combination with the Airtag seems to be able to get angular information but the antenna array might be provided in the tag rather than the Iphone. Thanks for your help!

I'm testing nearby interaction from my mobile device with accessory. After the mobile device generated Apple Shareable Configuration Data, the mobile device tried to send it to the accessory. After approximately 2 seconds, if the accessory didn't react, it would be a timeout. I want to send Apple Shareable Configuration Data from my mobile device to the accessory via the network, so I will try to increase the timeout on my mobile device. Could you help me with how to do it?

Now'sample can connected with one Third-Party Accessory to receive periodic measurements of its distance,I want to connect four accessories（not iPhone） to receive their distance and direction at the same time ,How to do that. please tell me if you know how to do that，thank you very much！

HELLO 😊 I want to range two iphones 11 to single of DWM3000EVB device at the same time (simultaneous ranging /measuring distance )via UWB nearby interaction framework will i be able to do it ? how to do it ? please let me know the code example on the side of iphone11 (swift code ) and the code on the side of DWM3000EVB how many maximum of iphones 11 are able to range / interact to one of DWM3000EVB simultaneously with UWB ranging in order to get distance ? the series or model of u1-equipped iphone is the factor of amount of iphones when UWB ranging ? for example iphone11 range to one DWM3000EVB or iphone 12 range to one DWM3000EVB or iphone 13 range to one DWM3000EVB or iphone 11 /12 /13 , 3 different series 's iphones range to one DWM3000EVB in the same event simultaneously , please let me know Thank you very much！ please see the picture below

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.

By referencing to the Developer Forums, we could handle multiple concurrent sessions using iphone11. The maximum number of concurrent sessions is two. When we try to connect another one devices, session(_:didInvalidateWith:) on the NISessionDelegate is called with NIError.Code.activeSessionsLimitExceeded. I'd like to know three or more concurrent sessions are running using newer version like iphone12. Does anyone have any knowledge?

Dear Apple developers, I am a developer of smart home. As for the application of UWB technology in smart home, do traditional smart home manufacturers need to access Apple'S UWB chip

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
