I am trying to turn an iOS device into a Bluetooth keyboard/joystick peripheral. I know iOS 16 supports the HID profile for communication with Bluetooth keyboards and game controllers (https://support.apple.com/en-us/HT204387). However, is it also possible for an iOS device to act as a HID device, advertising services like the HID?
I've seen an app, BlueTouch seems to make the similar functionality, and sample code on Github (https://gist.github.com/conath/c606d95d58bbcb50e9715864eeeecf07) suggest this might be possible. Has there been any change in iOS that would allow an iOS device to act as a Bluetooth HID device? Could you point me to the relevant documentation or sample code?
Thanks for any guidance you can provide.
