I need that as well, but for a wired ethernet interface. It‘s quite a burden to require the user to set a static IP and netmask before my app can talk to the device I need to talk to. Should I just file a feedback request via the reporter?

I'd love to know this as well – did you find a solution yet?

For me neither… could it perhaps just be broken in modern iOS versions? When did you see it last time?

Did you find a method in the meantime? I don't care about app-store-safe or not, but it's pretty annoying that this is no longer possible, in particular, because iOS15 seems to have broken the auto-connect to known Bluetooth devices for everything but audio devices.

Did you solve your problem? I'm having the same since macOS 12 which seems to have even more stricter rules. My SPM-based command-line-utility https://github.com/mickeyl/core-bluetooth-tool no longer works due to these rules.
