I want to use iPhone as a bluetooth keyboard or joystick to control a host device. To input contents or play games on another device. As far as I know. My goal can't be done. There are three relate frameworks: CoreBluetooth. When I try to add a peripheral with HID service 1812, the method returns a error. There's another HID service 1124, over BT classic. Is it available? ExternalAccessory. Our host device is not a MFI device. GameController. By this iPhone can work as a host device, not a input device. Thanks for any suggestions!
