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.

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?

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?

Hello, What is the best and Apple recommended way to get display name and its vendor information? The CoreGraphics framework provides ModelNumber and VendorNumber only. Looks like IOKit does not provide any documented way at all. Are there any daemon safe way to get such information? Thank you in advance, Pavel
