Forum - RPi 3 Bluetooth keyboard

Hi

Is it possible to use a Keyboard using the internal bluetooth of the RPi 3? So we free a USB port, and maybe is needed less power consume.

How could it be done by a newbie?

Maybe you have to make your devices visible Dodgy

you were right.
But now I can't write anything of this:
>> power on
>> agent KeyboardOnly
>> default-agent
Just no character is showing in the terminal when I type:

Terminal

xbian@xbian ~ $ bluetoothctl -a
[bluetooth]#

Certainly does not seem to work. Might be an issue with the package A2DP.

dmesg shows:

Looking on the forums, seems to suggest a pre-installed package called "pi-bluetooth" is required.

Looks like a "hack" is required

Terminal

$ sudo apt-get install bluez-firmware

$ sudo reboot

Terminal

xbian@xbian ~ $ hcitool dev

Devices:

Turn on keyboard and set it to scan mode.

Make a note of this address 00:00:00:00:17:41 (Yours will be different)

The sudo here is important, if not used you will loose the use of the keyboard!

Awesome, working.
Thanks

EDIT: After restarting Kodi, it keeps working.
It works better than in OE, since it doesn't ask a PIN each time you use the keyboard.
