Can a phone pretend to be a Bluetooth keyboard?

Question

It seems like it would be super useful if an app existed for iPhone/Android that emulated a Bluetooth keyboard or mouse. e.g., you turn on the app, and suddenly you can type on

Answer 1

The public iOS APIs do not currently appear to expose any functionality that would allow an app to make the iOS device to appear as a generic keyboard HID on Bluetooth.

However, iOS apps (iOS 4.2 and later?) can use external Bluetooth keyboards for input.

Answer 2

I'm surprised nobody has answered pointing out BlueputDroid as an Android solution for that. At the link you can find further information about device compatibilities.

I know this thread is rather old but I think it's worth to let it documented so others would end up here as me and will find an answer, at least for the Android half of the question.

Answer 3

This is possible on Blackberry 10 devices. Use the app called: bluetooth keyboard-mouse. I have been looking but I don't think Android or IOS have capability to appear as a bluetooth hid device
