    ControlBlock ? (with some additional features)

    ControlBlock: Power Switch, Game Controllers, and I/O for the Raspberry Pi

    Or if you want to build it completely yourself using MCP23017 like ControlBlock or the “IO Pi” from your second link does is the correct way.

    I have paired my bluetooth keyboard (Logitech Cordless MediaBoard Pro) and a PS 3 controller (mostly) successful.

    What i have done:
    PS3 controller already successful connected, to connect the keyboard.

    sudo sixad --stop
    sudo sixad -r

    (the second command to remove sixad temporary)
    And now added the keyboard following this guide:
    http://elinux.org/RPi_Bluetooth_keyboard_setup
    (sometimes an additional “sudo” is required, for example
    “echo 0000|sudo bluez-…” instead of “echo 0000|bluez-…” and it worked)

    Now after restarting sixad (“sudo sixad –start” done at tty2) the bluetooth keyboard and the PS3 controller are working.

    Unfortunately, the reason why i wrote “mostly”, after a reboot most times both are working perfectly, but sometimes only one bluetooth device is recognized and working (keyboard or PS3 controller) and i have no clue why.

    Btw. RetroPie Pi 2 Version 3.0 BETA 4
