Hi Gilbert,

it should be pretty simple to implement a HID device role. There have been external projects in the past that did this. The reason why this is not in BlueZ is mainly due to the fact that we would need to get the input events from some kind of source. So if you have that figured out, then it should be simple to provided HID device role.
