Bluetooth keyboard pairs but does not appear as an input device? I purchased a bluetooth keyboard to use with my lenovo ideatab a2107 which runs android 4.0.3. The specific keyboard is the:

Anker® Ultra Slim Bluetooth Wireless Keyboard for iPad Mini, iPad 4, New iPad 3, iPhone 5, Android 3.0 and above Tablet - Black

I am able to pair the keyboard with my tablet and the it has a keyboard icon next to it in the list of bluetooth devices. When this happens I am asked to type a 4 digit code and press enter on the keyboard. This works fine.

The Keyboard does not show up in tablet's keyboard &amp; input devices list and I am unable to input text using the keyboard. How can I get the keyboard working properly with my tablet?

Thanks
Found a possible solution from Android Central questions give it a shot.

Specifically, this post says to do the following:


  When pairing the keyboard with your device, it will prompt you to
  enter a pin and say "try 0000 or 1234." You need to:
  
  Step 1) enter "0000" on your android device (tablet or phone
  keyboard) Step 2) hit "okay" Step 3) type "0000" and hit enter
  on your BLUETOOTH keyboard
