iPhone: iPhone 12 pro max, iOS:18.3.1 Step: Connect CarPlay to my car, after connection success, CarPlay screen is black. This issue only happens of first time connection; I have asked OEM factory, they told me because of my iOS version is larger than 17.5, and above this version, will have this issue. So, I need your help to figure problem and update in new version.

The issue is, I cannot auto acquire bluetooth keyboard focus in PHPickerViewController after enabling 'Full Keyboard Access' in my IPhone 14 with iOS version 18.3.1. The keyboard focus in PHPickerViewController will show, however, after I tapped on the blank space of the PHPickerViewController. How to make the focus on at the first place then? I'm using UINavigationController and calling setNavigationBarHidden(true, animated: false). Then I use this controller to present PHPickerViewController using some configuration setup below. self.configuration = PHPickerConfiguration() configuration.filter = .any(of: filters) configuration.selectionLimit = selectionLimit if #available(iOS 15.0, *), allowOrdering { configuration.selection = .ordered } configuration.preferredAssetRepresentationMode = .current Finally I set the delegate to PHPickerViewController and call UINavigationController.present(PHPickerViewController, animated: true) to render it. Also I notice animation showing in first video then disappear.

The device is connected to Bluetooth A and Bluetooth B, currently the audio is played through Bluetooth A, click the interface button, how to realize the code to switch to Bluetooth B？

Hi, I'm developing a bluetooth peripheral. During factory reset I generate a new IRK and drop any bond information it has. When I then try to bond again with the device iOS returns bonding failed with 0x08 (unspecified reason). I assume that iOS somehow still thinks my reset device is the same as the device it has already bonded with. What information about the device is it using to draw this conclusion? Bonding works if I remove the "pre-reset" peripheral from the iOS list of bluetooth devices. Regards

Hi guys, I am having issue in live-streaming audio from Bluetooth headset and playing it live on the iPhone speaker. I am able to redirect audio back to the headset but this is not what I want. The issue happens when I am trying to override output - the iPhone switches to speaker but also switches a microphone. This is example of the code: import AVFoundation class AudioRecorder { let player: AVAudioPlayerNode let engine:AVAudioEngine let audioSession:AVAudioSession let audioSessionOutput:AVAudioSession init() { self.player = AVAudioPlayerNode() self.engine = AVAudioEngine() self.audioSession = AVAudioSession.sharedInstance() self.audioSessionOutput = AVAudioSession() do { try self.audioSession.setCategory(AVAudioSession.Category.playAndRecord, options: [.defaultToSpeaker]) try self.audioSessionOutput.setCategory(AVAudioSession.Category.playAndRecord, options: [.allowBluetooth]) // enables Bluetooth HFP profile try self.audioSession.setMode(AVAudioSession.Mode.default) try self.audioSession.setActive(true) // try self.audioSession.overrideOutputAudioPort(.speaker) // doens't work } catch { print(error) } let input = self.engine.inputNode self.engine.attach(self.player) let bus = 0 let inputFormat = input.inputFormat(forBus: bus) self.engine.connect(self.player, to: engine.mainMixerNode, format: inputFormat) input.installTap(onBus: bus, bufferSize: 512, format: inputFormat) { (buffer, time) -> Void in self.player.scheduleBuffer(buffer) print(buffer) } } public func start() { try! self.engine.start() self.player.play() } public func stop() { self.player.stop() self.engine.stop() } } I am not sure if this is a bug or not. Can somebody point me into the right direction? I there a way to design a custom audio routing? I would also appreciate some good documentation besides AVFoundation docs.

I have been trying to investigate some of the kernel crashes I have noticed on my IOS crash logs. Some of these are in device driver software for the peripheral interfaces. Given that the driver code executes with kernel privileges, these kind of crashes leave the device vulnerable to remote code injection, with no user interaction required in some cases. Crash Report from IOS 18.2.1 If Apple can provide the symbol table for IOS 18.2.1 blue tooth driver and source code, I can gladly help investigate this further.

I have an app that I'm using for my own purposes and is not in the app store. I would like to run an http server in the background for more than the allotted 3 minutes to allow persistent communications with a connected Bluetooth device. The Bluetooth device would poll the service at intervals. Is this possible to do? This app does not need app store approval since it's only for personal use.

How to encrypt bytes with CCM method in KMP?

Hello. In my app, I need to implement the following mechanism: I need to collect data from nearby Bluetooth devices, process them, and send this information to the server at short intervals, including when the app is minimized. Is this possible on iOS? BGProcessingTask has restrictions related to battery saving policies and does not guarantee task execution at specific intervals. Additionally, there is a limitation on background task execution, which can occur no more frequently than every 15 minutes. However, some apps, such as Google Maps, work in the background and update geolocation data. Could you suggest a solution for this task? Thanks for any help on this topic

Hello, I am working on a Flutter application where I need to use Bluetooth Low Energy (BLE) in Peripheral mode to advertise data even when the app is in the background (or when the screen is turned off) on iOS devices. I am using the package flutter_ble_peripheral to handle BLE advertising and peripherals. My goal is to make sure that the BLE advertising continues running when the app is minimized or in the background. Here is what I have already done: Added the required Bluetooth permissions in Info.plist. Enabled Background Modes in Xcode (with Bluetooth LE Accessories enabled). Used the FlutterBlePeripheral.start() method to start advertising. However, when I minimize the app or turn off the screen, the BLE advertising seems to stop. I have ensured that the app is not terminated but still the advertising is not persistent. I would like to confirm whether flutter_ble_peripheral works reliably in the background on iOS, or if there are any additional configurations or limitations I need to consider to ensure that advertising continues in the background. Any insights or experiences would be greatly appreciated. Thanks!
