During the Wi-Fi Aware's pairing process, Apple is unable to recognize the follow-up PMF sent by Android.
iPhone 12 pro with iOS 26.0 (23A5276f) App: https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps We aim to use Wi-Fi Aware to establish file transfer between Android and Apple devices. Apple will act as the Publisher, and Android will act as the Subscriber. According to the pairing process outlined in the Wi-Fi Aware protocol (Figure 49 in the Wi-Fi Aware 4.0 specification), the three PASN Authentication frames have been successfully exchanged. Subsequently, Android sends the encrypted Follow-up PMF to Apple, but the Apple log shows: Failed to parse event. Please refer to the attached complete log. We request Apple to provide a solution. apple Log-20250808a.txt

IOS App tcp connect and local network permission
Recently, my application was having trouble connecting socket using TCP protocol after it was reinstalled. The cause of the problem was initially that I did not grant local network permissions when I reinstalled, I was aware of the problem, so socket connect interface worked fine after I granted permissions. However, the next time I repeat the previous operation, I also do not grant local network permissions, and then turn it back on in the Settings, and socket connect interfcae does not work properly (connect interface return errno 65, the system version and code have not changed). Fortunately, socket connect success after rebooting the phone, and more importantly, I was able to repeat the problem many times. So I want to know if the process between when I re-uninstall the app and deny local network permissions, and when I turn it back on in Settings, is that permissions have been granted normally, and not fake, and not required a reboot to reset something for socket coonnect to take effect.

wifi connect fail
Dear Apple: We encountered a problem when using the Wi-Fi connection feature. When calling the Wi-Fi connection interface NEHotspotConfigurationManager applyConfiguration, it fails probabilistically. After analyzing the air interface packets, it appears that the Apple device did not send the auth message. How should we locate this issue? Are there any points to pay attention to when calling the Wi-Fi connection interface? Thanks

wifi connect fail
Dear Apple: In our app, we will call the - (void) applyConfiguration:(NEHotspotConfiguration *) configuration completionHandler:(void (^)(NSError * error)) completionHandler; interface of NEHotspotConfigurationManager on Apple devices. However, we are encountering a problem where the connection to the 2.4G hotspot fails, and the error is nil when it fails. We checked the Wi-Fi air interface and found that the Apple phone does not send a probe request before connecting to the hotspot. However, we are unclear why the Apple device does not send the probe request frame. Could you please help us understand when the probe request frame is not sent during the hotspot connection and how to trigger it to send the probe request frame every time? Thank you.

On an iPhone 17, using the NEHotspotConfigurationManager::applyConfiguration interface to connect to Wi-Fi is extremely slow, typically taking more than 20 seconds.
Title: iPhone 17 Wi-Fi connection via NEBOTspotConfigurationManager::applyConfiguration is significantly slower compared to other models Description: When using the NEBOTspotConfigurationManager::applyConfiguration API to connect to a Wi-Fi network, the connection process on iPhone 17 is extremely slow compared to other iPhone models. For example, in one test case: The API call to connect to Wi-Fi (LRA-AN00%6149%HonorConnect) was initiated at 16:16:29. However, the Association Request was not actually initiated until 16:16:58. During this ~29-second delay, the device appears to be scanning before starting the association process. This issue is specific to iPhone 17 — the same code and network environment do not exhibit this delay on other iPhone models. Steps to Reproduce: On an iPhone 17, call NEBOTspotConfigurationManager::applyConfiguration to connect to a known Wi-Fi network. Observe the timestamps between API invocation and the start of the Association Request. Compare with the same process on other iPhone models. Expected Result: The Association Request should start almost immediately after the API call, similar to other iPhone models. Actual Result: On iPhone 17, there is a ~29-second delay between API call and Association Request initiation, during which the device appears to be scanning. Impact: This delay affects user experience and connection performance when using programmatic Wi-Fi configuration on iPhone 17. Environment: Device: iPhone 17 iOS Version:26.0.1 API: NEBOTspotConfigurationManager::applyConfiguration Network: WPA2-Personal IOS.txt

Why app clips card action not open the main app while main app is installed?
App Clip target is added to my main app, and set associated domains such as appclips:example.com both in clip and main app. 2.Register local launch experience with url prefix https://example.com in my IPhone device. 3.Generate a QR code with this url. When scanning the QR code ,a clip card popped up, but clip the open action button ,always laugh clip not the main app although main app is already installed. How should I test the clip card to the main app route to check if the main app process the url rightly? Any suggestions are welcome.

socket connect error 65
Dear apple: Our app uses the BSD socket interface for socket communication over the local area network. However, when using the socket's connect interface, some iPhone devices fail, and the socket has also bound the local Wi-Fi card's IP using the bind interface. The errno is 65, indicating "no route." We have checked that the app has already requested local network permissions and permissions to use the local area network. The TCP server on the other end is also listening normally. Please help us see if any additional permissions need to be requested. Thank you

BLE Scan Response
The iPhone XS Max and Garmin watch pairing cannot use BLE to send Scan Response; it can only send BLE advertisements. May I ask if this is a limitation of the Apple system? So far, we have tested several iPhone models, and only the iPhone XS Max has this issue. We are not sure if other untested models have the same problem.

Using NEHotspotConfigurationManager applyConfiguration interface for network connection, prompts "Unable to join network" errors.
When using the NEHotspotConfigurationManager applyConfiguration interface for network connection, there is a certain probability of encountering the "Unable to join network" error. We captured the system logs when the issue occurred, some errors are due to the network not being scanned, while others are rejected by the system(console logs like:WCLScanManager scan is blocked by other system activity 32 or 9). If there are any methods to optimize or avoid these errors?

Wi-Fi Aware: During the process of establishing a NAN data path between Android and Apple, why doesn’t Apple respond to the NDP response?
Our goal is to establish a Wi‑Fi Aware data path (NDP) between Apple and Android devices. Apple will act as the Publisher, and Android will act as the Subscriber. Apple-to-Android pairing has already been completed. The Android device can be normally displayed on the Apple official Wi-Fi Aware Sample. However, the indicator is not green. During pairing, the Apple log shows: state: authenticated, and the Android side triggers the callback onPairingSetupSucceeded. During pairing verification, the Apple log shows: state: authenticated, and the Android side triggers the callback onPairingVerificationSucceed. The Android side sends an NDP request to Apple (as shown in the figure 1), but Apple does not reply. Note: Qualcomm’s NDI and NMI are different. In addition, after Apple-to-Apple pairing is completed, the paired device will be recorded in “Settings → Privacy & Security → Paired Devices”. However, after Android-to-Apple pairing is completed, the device is not saved to this list. My iPhone model: iPhone 13, iOS 26.0 (23A5287g).

BLE ADVERTISE
Dear Apple: The program we developed uses BLE broadcasting to discover devices. The discovered device sends three broadcasts, but when we debug the program, we found that the addresses reported by centralManager::didDiscoverPeripheral for the same device's three broadcasts are actually different CBPeripheral * addresses. I would like to ask how we can identify that these three broadcasts are from the same device? Are there any variables in the peripheral that can identify it as the same device? Thanks。
