Normally, MFI isn't needed if you just want to achieve GATT over BR/EDR and your accessory supports it.

Hello, did you have any news about this ? It seems that the bluetooth API from External Accessory has been removed from recent SDKs.

It is mind-boggling that there isn't a simple API, even a simple boolean or an enum value on UIApplication like UIApplication.localNetworkAccessAuthorizationStatus where we could simply check this. We have various flows where we want to delay and/or control the apparition of the system alert due to internal sockets being opened and we have to finally rely on a Network browser object to somewhat control it...
