Hello I've noticed that this product, heavily promoted on the ASC forums for many years, is no longer available from the Apple App Store. Can anyone tell me the reason why the product is no longer supported? Friends have asked me if it is 'safe' to use. Is it? Note to moderator: If I'm asking in the wrong places, please redirect my question. Thank you.

I am creating a barcode reader using the AVfoundation framework for iOS and IPadOS. The read result goes into payloadstringvalue, but I want to check the control characters contained in the symbol, so I am using the raw data of the description, which is a property of NSObjectProtocol inherited by VNBarcodeObservation. However, I noticed that if the length set in the raw data exceeds 26, some of the raw data in the description is omitted. So my question is, is it possible to set it so that all the raw data in the description is written out without omitting any raw data? If so, could you please tell me how to set this up? Also, if you know of any other way to extract the raw barcode data, I would appreciate it if you could let me know. Thank you.

I am working on a Bluetooth Low Energy (BLE) project using the nRF52840 Development Kit (DK), which has been reconfigured to simulate an nRF52805 chip. The firmware is based on Nordic Semiconductor's ble_app_hids_keyboard example, with modifications to implement a BLE HID Gamepad. I am using the S113 SoftDevice and have successfully tested the functionality with Android devices. The gamepad is recognized as a HID device, and it works as expected on Android, verified using the hardwareTester website. However, when I connect the gamepad to an iPhone via BLE, the same hardwareTester website does not respond as it does on Android, indicating that the iPhone does not recognize the device as a gamepad. The BLE connection is established successfully, but it seems iOS does not interpret the HID report descriptor or the BLE HID service correctly. I suspect there might be compatibility issues with the HID descriptor or the GATT attributes for iOS-specific BLE HID requirements. I would like to have some help.

i never imagined that an apple product could do such. a thing . i 've updated to the latest version , 15.3 what should i do next time? i've had to restart it three times, the last one finally helped here is the link https://youtu.be/-aqjzVKMZGA

I have a C++/Objective-C command line application, running on MacOs (15.1.1 (24B91)), that communicates with a Bluetooth LE peripheral. The application is build with Apple clang 16.0.0 and CMake as build system using Boost.Asio. I'm able to establish a L2CAP channel and after the channel is established, the peripheral sends a first (quite small) SDU on that channel to the application. The PSM is 0x80 and was chosen by the peripherals BLE stack. The application receives the PSM via GATT notification. I can see the SDU being send in a single LL PDU with Wireshark. I can also see the SDU being received in Apples PacketLogger. But I miss the corresponding call to a stream event handler. For all other GATT related events, the corresponding delegates / callbacks are called. The code that creates a dispatch queue and passes it to the CBCentralManager looks like this: dispatch_queue = dispatch_queue_create("de.torrox.ble_event_queue", NULL); manager = [[CBCentralManager alloc] initWithDelegate:self queue:dispatch_queue options:nil]; When the L2CAP channel is established, the didOpenL2CAPChannel callback gets called from a thread within the dispatch_queue (has been verified with lldb): - (void)peripheral:(CBPeripheral *)peripheral didOpenL2CAPChannel:(CBL2CAPChannel *)channel error:(NSError *)error { [channel inputStream].delegate = self; [channel outputStream].delegate = self; [[channel inputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[channel outputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[channel inputStream] open]; [[channel outputStream] open]; ... // a reference to the channel is stored in the outside channel object [channel retain]; ... } Yet, not a single stream event is generated: - (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)event_code { Log( @"stream:handleEvent %@, %lu", stream, event_code ); ... } When I add a functionality, to poll the input stream, the stream will report the expected L2CAP input. But no event is generated. The main thread of execution is usually blocking on a boost::asio::io_context::run() call. The design is, to have the stream callback stream:handleEvent to post call back invocations on that io_context, and thus to wake up the main thread and get that callbacks being invoked on the main thread. All asynchronous GATT delegate calls are working as expected. The only missing events, are the events from the L2CAP streams. The same code worked in an older project on an older version of MacOs and an older version of Boost. How can I find out, why the stream delegates are not called?

I upgraded my iPhone 13 Pro Max last week, but I am unable to connect my Sony WH-1000XM5 headphones via Bluetooth. I'm not sure why everything else connects just fine except my headphones. Please send help.

Six months ago I wrote FB14122473, detailing how the built-in CDC (or FTDI) VCP serial port driver is limited to 3 Mbps or less. Thing is, there are some FTDI devices that can do 12 Mbps (maybe more), and I have devices I need to communicate with at 4 Mbps. I had to use the FTDI SDK to be able to communicate with these. I was hoping this post might help draw attention to that bug report.

At present, I am using the avfoundation external device API to connect my iPad to a DSLR camera for data collection. On my end, I am using AVCapture Video Data Output to obtain raw data for processing and rendering. However, the pixelbuf returned from the system layer is incomplete, with only a portion cropped in the middle. But using the Mac API is normal. I would like to ask how to obtain the complete pixelbuf of the image on iPad

I have a 4-input, 4-output hardware device and an 8-input, 8-output virtual device, which I combine into an aggregate device. I am using the SimplyCoreAudio library to get the channel count. The code is as follows: aggregationDevice!.channels(scope: .input) =>> 12 aggregationDevice!.channels(scope: .output) =>> 12 When the program's MicrophoneMode is set to standard, the channel count is correct. However, when I set the MicrophoneMode to voiceIsolation, the channel count is incorrect: aggregationDevice!.channels(scope: .input) =>> 4 aggregationDevice!.channels(scope: .output) =>> 12 Below is the code for creating the aggregate device： func createAggregateDevice(mainDevice: AudioDevice, secondDevice: AudioDevice?, named name: String, uid: String) -> AudioDevice? { guard let mainDeviceUID = mainDevice.uid else { return nil } var deviceList: [[String: Any]] = [ [ kAudioSubDeviceUIDKey: mainDeviceUID, kAudioSubDeviceDriftCompensationKey:1 ] ] // make sure same device isn't added twice if let secondDeviceUID = secondDevice?.uid, secondDeviceUID != mainDeviceUID { deviceList.append([ kAudioSubDeviceUIDKey: secondDeviceUID, kAudioSubDeviceDriftCompensationKey:1, kAudioSubDeviceInputChannelsKey:8 ]) } let desc: [String: Any] = [ kAudioAggregateDeviceNameKey: name, kAudioAggregateDeviceUIDKey: uid, kAudioAggregateDeviceSubDeviceListKey: deviceList, kAudioAggregateDeviceMainSubDeviceKey: mainDeviceUID, kAudioAggregateDeviceIsPrivateKey:false, ] var deviceID: AudioDeviceID = 0 let error = AudioHardwareCreateAggregateDevice(desc as CFDictionary, &deviceID) guard error == noErr else { return nil } return AudioDevice.lookup(by: deviceID) } I hope someone can tell me the reason Thank you！

Currently, we use UIDocumentPickerViewController to read the user's connected sdcard. However, this requires the user to select manually, and the event cannot be monitored. But recently I found that ImageCaptureCore's ICDeviceBrowserDelegate can monitor the plug-in and unplug events in the didAddDevice callback, but cannot obtain the path of the storage card. I wonder if there is a way to combine the advantages of both, so that with the user's consent, the card reader events can be monitored and the content can be read directly without the user manually selecting the folder

why is it that this code doesn't show the bluetooth device name but in the iOS settings it is displayed correctly. Thank you. import UIKit import CoreBluetooth import CoreLocation class BluetoothViewController: UIViewController, CBCentralManagerDelegate, CLLocationManagerDelegate { var centralManager: CBCentralManager! var locationManager: CLLocationManager! override func viewDidLoad() { super.viewDidLoad() // Initialize central manager centralManager = CBCentralManager(delegate: self, queue: nil) // Initialize location manager to request location access locationManager = CLLocationManager() locationManager.delegate = self } // CBCentralManagerDelegate Methods func centralManagerDidUpdateState(_ central: CBCentralManager) { switch central.state { case .poweredOn: // Bluetooth is powered on, request location permission if needed if CLLocationManager.locationServicesEnabled() { locationManager.requestWhenInUseAuthorization() } startScanning() case .poweredOff: print("Bluetooth is powered off.") case .resetting: print("Bluetooth is resetting.") case .unauthorized: print("Bluetooth is unauthorized.") case .unknown: print("Bluetooth state is unknown.") case .unsupported: print("Bluetooth is unsupported on this device.") @unknown default: fatalError("Unknown Bluetooth state.") } } func startScanning() { // Start scanning for devices (you can add service UUIDs to filter specific devices) centralManager.scanForPeripherals(withServices: nil, options: [CBScanOptionAllowDuplicatesKey: true]) print("Scanning for Bluetooth devices...") } func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi: NSNumber) { // This method is called when a peripheral is discovered let deviceName = peripheral.name ?? "Unknown" let deviceAddress = peripheral.identifier.uuidString print("Found device: \(deviceName), \(deviceAddress)") // Optionally, you can stop scanning after discovering a device // centralManager.stopScan() } func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) { print("Connected to peripheral: \(peripheral.name ?? "Unknown")") } // CLLocationManagerDelegate Methods (for location services) func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) { if status == .authorizedWhenInUse { // Permission granted, now start scanning startScanning() } else { print("Location permission is required for Bluetooth scanning.") } } // Optionally handle when scanning stops or any errors occur func centralManager(_ central: CBCentralManager, didFailToConnect peripheral: CBPeripheral, error: Error?) { print("Failed to connect to peripheral: \(error?.localizedDescription ?? "Unknown error")") } func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) { print("Disconnected from peripheral: \(peripheral.name ?? "Unknown")") } }

Current if we use the removeAccessory(_:completionHandler:) method in ASAccessorySession, it removes the accessory from the system and all apps that have previously paired also lose access. Is there a way to remove the paired accessory only from the app from where the removeAccessory() call is being made? This would be useful in cases where one or more accessories are shared across apps and we need to manage them.

Hi, could you please help on the following points : Does iOS supports HCE Felica emulation support in Japan? Does iOS supports Felica card emulation using NFC &amp; SE platform ? Thanks

We would like to be able to distinguish between iPhones and Apple Watches when scanning for devices using a Laird BLE module. We know that we can identify an Apple device from the manufacturer data returned in the scan report. 0x004C is the registered identifier for Apple. In the remaining data returned is it possible identify the device type? We note that empirically, 4C001005 seems to correlate to an Apple Watch. How reliable is this? It is useful for us, because it means we do not need to connect to this device to see if it is advertising a service that we own. Connecting over BLE is of course an expensive operation. Here is a simple snippet of a Swift App doing a similar thing, to illustrate the question: func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) { guard let manufData: Data = advertisementData[CBAdvertisementDataManufacturerDataKey] as? Data else { return } let hexEncodedManufData: String = manufData.map { String(format: "%02hhx", $0) }.joined() print("Manufacturer Data: \(hexEncodedManufData): ") // Manufacturer Data: 4c001007351ff9f9036238: Apple device // Manufacturer Data: 4c001006331ec0640f88: Apple device // Manufacturer Data: 4c0010052b18804eb1: Apple watch? // Manufacturer Data: 4c0010052b18804eb1: Apple watch? }

I purchased an iPad Pro M4 in early December, and since day one, I’ve been experiencing a recurring issue. Almost every day, at random times, the device freezes for 1–5 minutes and then restarts itself. The tablet is not under heavy load when this happens — I mainly use it for light tasks such as watching videos in a player or Safari browser, web surfing, and reading books. The issue has even occurred while the iPad was idle and locked; it froze, displayed the Apple logo, and rebooted. I brought the device back to the store where I purchased it, and they sent it for a diagnostic check. However, the experts concluded that the device is fully functional, and no defects were found. After one of these crashes, I noticed that my Apple Pencil started lagging (see video file IMG_5688.MOV). However, after another reboot, the issue with the Apple Pencil resolved itself. I’ve documented the issue with several video recordings showing the freezing and rebooting behavior, as well as error logs generated after such incidents. Device Details: Model: iPad Pro M4 Usage: Light tasks only (video streaming, web browsing, reading) Environment: No overheating, no resource-heavy applications running What could be causing this issue, and how can I resolve it? Any help would be greatly appreciated. Thank you! P.S. I’ve uploaded all the device logs and videos demonstrating the issue to Google Drive. https://drive.google.com/drive/folders/1_R0i_iazADWo5EgStrPdgmf1XjgPP_RC?usp=sharing

what do i do is it going down too fast?
