And I'd like to know if MFi Program is required for iAP2 connection. I'd appreciate it if you could let me know the detailed procedure for iAP2 connection.

Hello everyone, I'm trying to configure my WAC device trough an App. This App finds the device without problems using startSearchingForUnconfiguredAccessoriesMatchingPredicate but when I try to use configureAccessory method I get only 3 messages in Xcode and nothing happens. These messages are: 2024-03-14 12:55:56.261969+0000 App[1394:380785] ### WAC: -[EAWiFiUnconfiguredAccessoryBrowserManager configureAccessory:withConfigurationUIOnViewController:]_block_invoke_3:368 Other Region SKU 2024-03-14 12:55:56.266191+0000 App[1394:374248] ### WAC: _notificationCleanup:42 responseFlags: 3 ### WAC: _notificationCleanup:43 responseFlags: 3 For me they don't look like an Error but would be nice if someone could give me some advice on this, I didn't find nothing about it. Thanks in advance!

Is there a possibility to develop an iOS app that is connected to an external camera connected through lightning or USB-C port and receives video stream. We need to be able to get this video stream even while the app is in the background or if the phone is locked. We could have the camera connected wirelessly through the lightning port. Is there an available library or a sample app featuring such functionalities. Thanks.

Hello, Apple Developer Community, I am currently developing an iOS application using .NET MAUI. In this application, I need to use the ExternalAccessoryFramework to communicate with external devices. However, I couldn't find any information about the compatibility of MAUI and ExternalAccessoryFramework, and I would like to confirm whether this combination is possible. Can an iOS app developed with MAUI use the ExternalAccessoryFramework? If so, could you provide any guidelines or reference materials about its implementation? I would greatly appreciate it if you could share your knowledge and experience. Thank you in advance.

Hi, I am inquiring in regard to how to handle data from a bluetooth device. The device would send data in JSON format to a Mac via bluetooth, and I would need to constantly refresh or fetch data from the device in real time. How would I go about this? Any help would be greatly appreciated. Thank you.

Before iPhone 15, the lighting interfaces required communication with external devices through mfi authentication,But there is no evidence to suggest that the USB-C interface needs to add an MFi authentication chip for authentication detection. Is there a way to use USB-C to detect external devices and communicate with each other in the app now, so that I can create my app and communicate with hardware devices

Hi all, hope everyone is well. I'm seeking clarification regarding AirDrop functionality in regards to apps. For example, can the new AirDrop function within iOS17, whereby putting two iPhones together transfers user contact details to one another be utilised by an app? If not, please could I have clarification what bluetooth functionality within iPhone's an App may be able to utilise and could an app connect to AirDrop API's in any way? If the new AirDrop feature is not currently able to be utilised by apps, is this likely to change in the future with upcoming iOS updates or is it a set in stone thing? Apologies, I don't have the deepest understanding of this topic and any help is really appreciated, thank you.

Hi, Is it technically possible to stream external BT device's microphone input to iPhones speakers output?

Hey there 👋, My team and me have implemented support for WAC devices in our App using EAWiFiUnconfiguredAccessoryBrowser. When the device we want to support is factory reset we are able to find it as well as the OS is able to. The device has a "setup wifi" button, which starts the WAC process, and iOS (as well as MacOS) are able to find it. Unfortunately we are not able to find it in that case using EAWiFiUnconfiguredAccessoryBrowser.. I could not find any restrictions on it in the documentation, any glues why we are not able to detect it in that situation? I isolated the problem in a sample and used the following implementation to test this: import Foundation import ExternalAccessory import os import Combine class WACWatcher: NSObject { private let browser: EAWiFiUnconfiguredAccessoryBrowser private let logger = Logger(subsystem: "WACWatcher", category: "networking") @Published var accessories: [EAWiFiUnconfiguredAccessory] = [] override init() { self.browser = EAWiFiUnconfiguredAccessoryBrowser() super.init() self.browser.delegate = self } func start() { browser.startSearchingForUnconfiguredAccessories(matching: nil) } func stop() { browser.stopSearchingForUnconfiguredAccessories() } } extension WACWatcher: EAWiFiUnconfiguredAccessoryBrowserDelegate { func accessoryBrowser( _ browser: EAWiFiUnconfiguredAccessoryBrowser, didUpdate state: EAWiFiUnconfiguredAccessoryBrowserState ) { switch state { case .wiFiUnavailable: logger.debug("WAC Browser state changed to wifiUnavailable") break case .stopped: logger.debug("WAC Browser state changed to stopped") break case .searching: logger.debug("WAC Browser state changed to searching") break case .configuring: logger.debug("WAC Browser state changed to configuring") break } } func accessoryBrowser( _ browser: EAWiFiUnconfiguredAccessoryBrowser, didFindUnconfiguredAccessories accessories: Set<EAWiFiUnconfiguredAccessory> ) { logger.info("WACWatcher found accessories: \(accessories)") self.accessories.append(contentsOf: accessories) } func accessoryBrowser( _ browser: EAWiFiUnconfiguredAccessoryBrowser, didRemoveUnconfiguredAccessories accessories: Set<EAWiFiUnconfiguredAccessory> ) { logger.info("WACWatcher removed accessories: \(accessories)") self.accessories = accessories.filter({ accessory in accessories.contains(where: { $0.name == accessory.name }) }) } func accessoryBrowser( _ browser: EAWiFiUnconfiguredAccessoryBrowser, didFinishConfiguringAccessory accessory: EAWiFiUnconfiguredAccessory, with status: EAWiFiUnconfiguredAccessoryConfigurationStatus ) {} } This WACWatcher gets used in a ViewModel and a view having a start stop button and a list showing the device name. If you'd need to see it, I can zip it and attach it to this post.

I am developing IOS application and trying to get the connected wifi information but i am only getting the status of the connection. I need more info e.g SSID. Pleas guide how can i get all the wifi information

One of our customers in US unable to connect to our device. current status: able to discover device, when trying to connect it throws an error " (error :Error Domain=EABluetoothAccessoryPickerErrorDomain Code=1 "(null)") " tried with different models, iPhone 11, iPhone XR, iPhone 15.. result is same. But It is working fine in Asia regions. Note: External accessory framework protocols has been added already in Info.plist. ( which has been registered in the MFi Program) Any help greatly appreciated. Thank you!

Hello Apple Support Team, As per the business requirement, we have to communicate and exchange data chunks between applications running on iPhones and Android-based or Android phones through Bluetooth interface. We have achieved the requirement through IP/Wifi communication. We are trying to connect to Android and iPhone devices via Bluetooth through an iOS application. We carried out Bluetooth implementation using CoreBluetooth libraries. Below are the findings done by our development team: Core Bluetooth Library Implementation           Importing Core Bluetooth Library in BTConnectionManager class, which uses CBCentralManagerDelegate, CBPeripheralDelegate, CBCentralManager, CBPeripheral as peripheral, [CBPeripheral] array as peripherals array. Using the below methods: centralManagerDidUpdateState, centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber), centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral), peripheral(_ peripheral: CBPeripheral, didDiscoverServices error: Error?), peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: Service, error: Error?) we are able to scan and connect to BLE devices Findings: We were able to get the list of low-energy devices like Airpods, Earphones and Bluetooth music devices. But Not able to scan Bluetooth high-energy devices like PAX / Android Phones   Please suggest to us the approach to make the Android running devices listed through the Core Bluetooth library. Thanks & Regards

I a macbook air 2020 m1 16Gb Ram and I'm having an annoying bug that started after i updated my mac to mac Sonoma 14.1. Whenever I connect an external display to my mac (hp e22 g4), mirror the screen and then start to watch a video the mac gets stuck. The keyboard doesn't respond, closing the lid doesn't help, only hard resetting the mac and causing to reboot seems to stop this. If I extend the display to the external monitor the bug doesn't occurs, it happen only when mirroring the screen. Tried different usb c to hdmi adapters, including high quality adapter, but it still happens. It didn't happened on older versions of mac os with the same adapter. Also, tried replacing the hdmi cable, but it doesn't seem to help. Can anyone help me with solving this issue? It's really annoying that I cant' mirror my mac's screen.

Hello Everyone, I am developing an IOS application for communicating with USB Flash Drive. For that I am going to use EAAccessory Framework. To be use EAAccessory Framework I need to mention protocol specification of USB Flash Drive (hardware) in info.plist file. Looking forward to know generic protocol specification which will enable IOS application to communicate with most or all USB flash drives.

Hi, I have an AOC 27G2 27" 144hz monitor running windows 11 connected to my 2019 14" mb m1 pro, running Monterey 12.5.1. Whenever I connect the two via hdmi the screen on my external monitor disconnects or the screen freezes and I cannot scroll anymore. Should I try usb-c to display port? Like this: https://www.amazon.com.au/DisplayPort-CableCreation-Thunderbolt-32-4Gbps-Compatible/dp/B08BXPVPPQ Wondering if anyone has had this issue or has a solution, cheers.

Will UVC native support come for the Iphone as well? So, using external cameras with the ipad is greatly beneficial, but for the iphone, it can make it a production powerhouse!

Hi, I have an iOS app that interacts with a USB accessory. This works fine when running on an iPhone or iPad. However, when I compile the app in Xcode to run on my M1 Mac, the app won't see any USB devices. The target I use is "My Mac (designed for iPad)" which was the path of least resistance when compared to trying Catalyst. Is it possible to give my app access to USB accessories when running on my Mac? If so, what settings do I need to change? I've tried setting the "com.apple.security.device.usb" entitlement to true to no avail. Is the issue that the app is running in some sort of sandbox?
