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.
