Hi everyone, I followed https://developer.apple.com/forums/thread/700295 to try to make sure one iPhone could perform UWB ranging with more than iPhone by creating a separate NISession for each phone and storing it in a dictionary, but I have not been able to get distance measurements from more than one phone at the same time. It seems that MPCSession allows all phones to see each other, but when it comes to UWB measurements, only 2 phones are able to exchange distance and angle measurements at the same time. It seems once an NISession starts working, it does not give other NISessions a turn to work. I set the MPC delegate to the same ViewController class, maybe that is the issue, but I have seen that Qorvo also set their Bluetooth connection delegate to the same class, and it works with their DWM3001CDK. Can you please help me make sure that each phone can receive distance and angle updates from multiple phones simultaneously?

Hello, I have a question regarding the UWB (Nearby Interaction) distance measurement feature. When testing with the iPhone 14 and UWB devices (DWM3000, DW3210, NXP SR040, SR150), measurements are possible up to 5-10 meters in an indoor environment without obstacles. However, when the UWB device is inside a car, distance measurement is possible only up to about 2-3 meters from outside the car. Based on these tests, Nearby Interaction seems to be a feature designed for close-range (visually perceptible distances, around 4 meters or so). It appears that the distance range for utilizing Nearby Interaction is somewhat limited. Do you have any data on the maximum distance range for UWB distance measurement with an iPhone?

We are implementing indoor positioning and proximity sensing in our iOS app using iBeacons. We have placed multiple beacons to detect the proximity of one point of interest(POI). We are using the startRangingBeacons method in the CLLocationManager class and implementing corresponding delegates to receive the ranging information. With all required foreground and background permissions granted, when a user walks from one POI to another, beacon ranging is working as expected and we are continuously receiving the sightings in the app. We have observed that, if user stops walking for a few minutes at a POI and then device automatically pauses the scan. Hence, we will not receive any beacon signals. When there is a movement, it performs beacon ranging again for a minute or so, then stops again for longer time even when user is walking. The interval between the pausing and resuming the service is not a constant. We have also observed that sometimes it takes more than 15 minutes to resume the service once the system pauses the ranging automatically. Is it an expected behavior? How long does it usually take for beacon ranging services to resume after the user starts moving? Is there any way we can reduce this delay between the pause and resume of ranging beacons? Appreciate your support

I am making an app like Taxi Driving, where users can add location and driver to that location. The problems I am facing are below: Drawing a route on MKMap - I get the route polyline and I render that on the map. Now what should happen as I am driving, the drove part of the polyline should get removed or may be turned grey, non-drove part should be blue. Currently, I am only able to do this by again getting a route from my current location and re-drawing on the map which is not a good thing I suppose. Show driving instructions - I need to show step-by-step instructions which I get in the MKStep under the MKRoute object. But I don't get the icons that I can show such as Turn Right or Turn left the only thing I have is plain text. I need an icon along with it and also how to identify once I have crossed the step and show the next step as my next instruction. These two are the major problems I am facing and I need to do this with Apple native map view itself so no third-party integration I want.

Hello, We are working with Nearby Interaction (UWB) technology to provide high-accurate location use cases to our customers. According to Apple's documentation, in order to enable background sessions starting iOS16, the two devices need to be paired. The accessory needs to implement Nearby service and mandated encrypted characteristic. https://developer.apple.com/documentation/nearbyinteraction/ninearbyaccessoryconfiguration So far we tested this with "PIN-based" secure pairing and everything works fine. Can you confirm if "Just works" PIN-less pairing is expected to work as well here? The documentation is not clear on this respect. We would basically indicate IoNone local capabitilities for the accessory gap parameters if this is expected to work. Thanks in advance! Regards.

I'm trying to develop a iOS mobile app with using flutter, which can scan nearby wifi access points and connect to a one of them. I ran the app on a physical device with a free apple developer account. When I scan for the wifi access points, it throws an error with saying wifi scan is not supported. I just used wifi_scan library in flutter. Is it required to have a paid developer account to test this feature (wifi scanning and connection) ? Does iOS natively give the access to apps to scan wifi? Thanks

Hello dear when i use geolocator after i'll get this error Could not build the precompiled application for the device. Error (Xcode): Undefined symbol: OBJC_CLASS$_LocationServiceStreamHandler Error (Xcode): Undefined symbol: OBJC_CLASS$_PositionStreamHandler Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation) Error launching application on iPhone. and didn't app running so plz guide i'm a too much upset

I understand that the Nearby Interaction framework is available on watchOS 8+, and I want to make a watch app that displays distance estimation between multiple watches (not iPhones) using UWB through Nearby Interactions. I see in the documentation that an iPhone can discover multiple device "discovery tokens" and create NISessions with them using the Multipeer Connectivity framework, but it looks like the Multipeer Connectivity framework is not available on watchOS? So, how might I make an independent watch app that can discover multiple nearby watches and setup NISessions with them? Thanks!

Hi, The nearby interaction app provided by apple gives me a range of just 15m and frequent data stops with my UWB hardware. However, the NXP Trimensions AR app gives a distance of more than 30 m with the same hardware non stop. Could anyone help me solve this issue Thank you https://developer.apple.com/documentation/nearbyinteraction/implementing_spatial_interactions_with_third-party_accessories

Hi all! Do you know if there is a sample project in Swift that I can use to detect obstacles using the Ultra Wideband?
