Android phone as bluetooth keyboard?

Question

Android

Given:
1. Android phone with a convenient physical qwerty-keyboard on 2.3.x
2. Android tablet on 3.x
Question: how could I make them friends so that I can use the phone (on which I type blindly and much faster) as a keyboard for a tablet, ideally, so that it is recognized simply as a regular bt device, but other options are also interesting.
Thanks in advance :)

Answer 1

you need a rooted phone, put AndroHID code.google.com/p/androhid/ on it (not in the market, you can get the binary from googlecode), this program will emulate the Bluetooth HID Profile that connects the mouse with the keyboard. Given that this is for rooted phones, and it uses non-official APIs, there is a very high probability that it will not work on a particular device.
