I want to send messages to other phones with a Bluetooth device. On android I can send SMS but iOS is a lot more restrictive. ANCS and MAP can read messages but not send them. Apple watches can reply to text messages but can any other devices do that? Samsung watch for example? How do they do it?
If it is not possible to send SMS/iMessage. Can I at least send a network request and handle the messages with my app, through firebase for example? I have seen that background processes are very limited. But I can't find if "Core Bluetooth Background Processing" can do simple http requests. I have seed that other people have issues with using internet while in background. Is it possible? Is there a correct way of doing it?
