I have a question about Apple certification. We are planning card reader via HID(human interface device) for iPad that support USB-C. iPad will receive data as HID protocol. In this case do I have to get certificate(for example MFi) like Apple USB accessory?

While compiling nRF5340 target of Dockkit ADK 1.0 following the guide of README.md, I selected the latest Nordic SDK, because there is no specified SDK version in the README.md. But it seems that ADK and SDK are not compatible with each others. For example, it calls nrfx_gpiote_channel_alloc() with one argument in PAL\NCS\HAPPlatformExperience.c. But the difinition of this function needs two arguments. Also I found that in some older version of Nordic SDK, this function needs only one argument. So could you please make sure which version of Nordic SDK should developer use?

Hi, We’re developing a BLE peripheral device and encountered a connection issue when connecting two devices (Device A and Device B) simultaneously to an iOS device. Problem: On iOS 18, we are experiencing occasional BLE timeouts and disconnections when both devices are connected at the same time. On iOS 16, we did not encounter this issue under the same conditions. What we’ve tried: Adjusted the connection interval from 30ms to 15ms. This seems to have improved stability somewhat. However, we still observe intermittent timeout/disconnection issues. Questions: Are there any known changes in BLE connection handling or timing constraints in iOS 18? Are there recommended connection parameter settings (interval, latency, timeout, etc.) for multi-device BLE connections in iOS? Is there a way to debug or log more details about the disconnection reasons on the iOS side? Any guidance or suggestions would be greatly appreciated.

After hardware and mobile phone hid mode pairing, the first connection is successful, after a while disconnect and reconnect,APP monitoring Bluetooth error NSLocalizedDescription = "Peer removed pairing information"; Failed to connect Hardware engineers detect the pairing information and find that the local pairing information of the iPhone has changed, which is a non-mandatory phenomenon

I am developing the electronic part of product, it includes a Find-My features. I saw some forum that testing Find-My feature needs a CSR and testing token. Can anyone teach me how to apply CSR and testing token step by step? Thank you very much. Best regards Sam Ng

I'm device manufacturer and in future planning to get my device matter certified. If I want my device data for analytics purpose into my cloud than what is the best way possible. My research says that the most latest approach suggested by apple is, developing a custom mobile app using device homekit sdk and subscribe to device state and send it to my cloud. If I go that route, will it work even though the device was onboarded via homekit app and homekit hub device is also there. I want to make sure that both path will be active, device to hub to home app and device to custom app to my cloud, and both on matter ecosystem. The homekit sdk and matter support mentioned here https://developer.apple.com/apple-home/matter, are these two same thing?

We are integrating the Microsoft Web Chat Control inside a WKWebView in our iOS application. The microphone button (used for speech input) works as expected when the app is active. However, we are facing an issue when the app is sent to the background and then brought back to the foreground. Issue Details: When the app returns from background to foreground: 🔹 The mic button becomes unresponsive (taps are not recognized). 🔹 No permission prompt or speech functionality is triggered. 🔹 Other elements of the Web Chat control continue to work fine. This issue seems isolated to iOS and WKWebView usage. We have verified that microphone permissions are granted and there are no system-level blocks.

I need to implement an app that exchanges data with peripherals through TypeC on Apple 15 phones, but I have two questions that I need to ask for help: Which library is used to communicate with peripherals through the TypeC port of the Apple mobile phone? Do peripherals need to pass MFi authentication before they can communicate with the App?

I want to get Cover-Art Image over Bluetooth. From the SDP Discover iPhoneSE, it support Cover-Art Feature. I connect and config OBEX Channel with L2CAP ERTM, it is successful. I send connect_request the OBEX Connect, the iPhone always no any response, and l2cap s-frame response from iPhone always failed. From the Apple Developer, it need Apple Authentication Chip. Is it still necessary now? Are there any other ways to obtain album pictures?

I opened a terminal window this morning and couldn't cd to /home. When I type a tilde, I get a paragraph symbol. Yesterday, my external keyboard could type a Pipe symbol, no such luck today. I ended up having to use hidutil to remap my keyboard and run keystrokes through terminal to restore what worked yesterday. When I look at the available English keyboards, they're all showing a paragraph symbol above the Tab key. Has anyone else run into this sudden keyboard change?
