Hi, I’m a CS university professor conducting research on assistive technologies. I’m looking forward to experimenting my own app based on nearby interaction between an iPhone and uwb devices (i.e., not iPhones). Which devices could I can use? Is it possible to use airtags? Thanks!

Hi 😊 anyone , framework engineer and Apple i just tested the nearby interaction with third party accessories from Qorvo DWM3000EVB module then run the sample app , regarding to the sample app from Qorvo as the result of the photo below i have seen the Qorvo NI demo app ,will be able to display the azimuth and elevation angle as 3D positioning , so my question are --> 1.--> the azimuth and elevation angle are measured by the angle of arrival , right ?🤔 2.--> regarding to the Qorvo NI demo app displaying the azimuth and elevation angle , both technically are measured by ** 3D AOA (angle of arrival) ** , right ??🤔 3.--> regarding to question 2. ,* if iphone11 use 3D AOA to get azimuth , elevation angle * so --> HOW MANY UWB antennas are in the iphone 11 ?? 🤔 because it can get angular measurement as the photo above (Qorvo NI demo app ) 🤔 , -->please can you figure out or show the diagram of antennas on iphone 11 or any u1 equipped iphone🥺 Please let me know 🥺

HI :)Apple , framework engineer i am appreciated for the help of Apple ,framework engineer that provide the third party nearby interaction framework with third party accessories 🙏😊 so , i just tested the evaluation kit from Qorvo ,DWM3000EVB attach on nRF52840DK , then testing the 2 sample apps and get the result as the photo below and on the monitoring screen on jlinkRttViewer so i found out that on the dwm3000evb has only one antenna ( and not antenna array type) , so it will not be able to achieve the 3D AOA ,azimuth ,elevation angle ON THE SIDE OF dwm3000evb , because dwm3000evb ,base on dw3110 that has only 1 antenna ,as the green rectangle area photo below and the dw3120 also come with only 2 antennas , so i can get only 2D AOA (angle of arrival ) however i can get 3D AOA ,azimuth ,elevation angle FROM THE IPHONE11 SIDE as the photo of QorvoNIdemo_app.jpeg above , i think u1 equipped iphone has at least 3 antennas , that why it can display 3D AOA so in this moment , all chip and Evaluation kit that sell on Qorvo web page , there are none of them that can get 3D AOA in this moment then i looked for NXP . in this moment, there are 3 companies that sell the UWB accesories , however mk uwb mobile knowledge evaluation kit vendor and sunway vendor do not have 3 antennas on board , both vendors has only 2 antennas so there are 2 antennas on board , regarding to the photo above from 2 companies , so it can achieve only 2D AOA but from the UWB Development Kit: Murata Type2BP EVK there are 3 antennas on the board , so it can display 3D AOA , azimuth ,elevation angle on the board side as it did on the iphone11 side from the photo on the top of article but i try to ask for the price and already sent the inquiry to murata , but nobody contact me back 😥 I JUST WANT TO TEST TO GET 3D AOA azimuth ,elevation angle on the SIDE of the third party accessory (not the iphone11 SIDE ) ,and display the result on the monitoring screen on the laptop as an example of displaying on the jlinkRttViewer photo on top my purpose of my post are --->.😉 so i posted this article because** i just want to ask,(please) APPLE to tell QORVO to produce the evaluation kit with (3 antennas ) that will be able to measure 3D AOA as it has done on the iphone 11 side , because there are many developers waiting for it 🥺🙏 ps. Apple bought Decawave then change the name to Qorvo , so it is not too hard , if Apple tells Qorvo to do it😉 and i personally think , the board from Qorvo is more affordable than other , the more affordable price and more functionality as 3D AOA , the more creative apps with third party accessories ,it is going to be , FOR APPLE 2.and Apple please tell the third party accessories as MURATA https://www.nxp.com/products/wireless/secure-ultra-wideband-uwb/uwb-development-kit-murata-type2bp-evk:UWB-DEV-TYPE2BP-EVK to make it more easier in order to sell the evaluation board to the developers as opening the credit card channel to let developers make payment and buy it easier , instead of needing to send an inquiry , it is harder to get feedback , even me , have not gotten any feedback from murata after sending more than week to ask the information of the board🥺😥 , because there are many developers as me want to test the board with 3 antennas as murata has it ps. hopefully , Apple and framework engineer will understand the voice of very tiny developer who loves Apple 😊🍏

About Qorvo NI demo app , i am not so understanding about how azimuth and elevation angle are measured ,please let me know 🥺 during testing the Qorvo ni demo app with iphone11 sometime the 3d arrow moving so slow and sometimes got frozen about 10 seconds then slowly moving to point to the dwm3000evb and sometime does not aim correctly . I do not know why ? you know why ?? :face_with_raised_eyebrow: :thinking: even i carry the iphone11 vertically as the recommendation from nearby interaction framework for azimuth and elevation angle , please correct my understanding instead of the sun in the photo, it can replace sun with dwm3000evb and man is replaced by iphone11, you can imagine it out :slightly_smiling_face: 2.1 ) for azimuth , is the angle that measured North to the ideal line of sight that draw from iphone11 to dmw3000evb ? 🤔 as like the photo 2.2) for elevation angle , is measured from plane line (observer local plane ) to the ideal line of sight that draw from iphone11 to dwm3000evb ??🤔as like photo

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

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

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！

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.

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

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?

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 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.

I would like to hear from you.

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?
