Hello, I am in a very similar situation as described in the thread: https://developer.apple.com/forums/thread/655183 Context: I am working on an app that receives data from a hardware device through its Wifi network, and the hardware is not connected to the internet. Now, I would need to call some API while still connected to hardware so I would need to use the cellular data. As mentioned on the thread, I can achieve this via Network framework, using the requiredInterfaceType property. But Is there any other way I can achieve this? I can also do some suggestion on the hardware if that's helpful. Thank you!

Hello, I am planning to create an app that can transfer files to hardware devices via WiFi. With devices like GoPro, I believe the typical setup involves the GoPro creating a WiFi hotspot to which the iOS app connects, allowing file transfers. But this setup establishes a 1:1 connection between the app and the hardware. To support multiple hardware devices simultaneously, I am considering reversing this setup: the iOS device would create a personal hotspot, and the hardware devices would connect to it. However, I have concerns about this approach: Reliability: I have read that the personal hotspot feature on iOS devices can be unreliable, especially with non-Apple devices, which tend to disconnect frequently. Manual Setup: There is no API to programmatically create the personal hotspot, so users would have to enable it manually in the Settings. I can use isIdleTimerDisabled to prevent the iOS screen from going to sleep, which might help with disconnection issues. Aside from this, are there other things I can do to ensure a stable connection? Given my limited experience with hardware connections, I am uncertain if having the iOS device act as the WiFi access point is a good design. Any advice or alternative solutions would be greatly appreciated. Thank you in advance!
