I have connected the bluetooth keyboard Rii mini i8+ to my Ubuntu 16.04 running on a NUC. I can find the keyboard, connect it, but it simply wont act as keyboard or mouse/trackpad.

Tried it on different hardware like Win7 and Firestick, works there like a charm.

Any idea?

Many thanks in advance, Kazchen

Kazchen,

I also have a Rii BT Keyboard that I tried connecting to Ubuntu 16.04. I ran into the same exact issues as you and went down the rabbit hole of messing with my bluetooth settings which is suggested on all forums regarding this question. However, it has nothing to do with bluetooth at all (even though I received a minor bluetooth error when connecting to the device). If you can press some of your numbers on the number key row and a few of the letters on the right side, such as Y or U, and see if it responds and gives you input. The input should be a random number between 1-9 that does not correspond to what is printed on your keys. If you can reproduce that exactly, here are the steps to fix the issue:

  • Plug in a secondary keyboard to USB (do not disconnect bluetooth)
  • Numlock should be automatically turned on. Turn it off.
  • Voila! May require restart.

  • Awesome! Turning off numlock worked for me. This should be the accepted answer. Thank you!!

I got one working connected to a friends R-Pi (not running 16.04 though). These were the steps (from my notes):

Open a terminal and enter the following commands

sudo bluetoothctl -a
power on
agent KeyboardOnly
default-agent
pairable on

Enter discovery mode on your keyboard

scan on

You should see your keyboard appear on the list. Copy its MAC address (xx:xx:xx:xx:xx:xx) to the clipboard.

Now type

pair MAC_ADDRESS
trust MAC_ADDRESS
connect MAC_ADDRESS

where MAC_ADDRESS is the address you copied to the clipboard.

You should see something like:

[bluetooth]# connect xx:xx:xx:xx:xx:xx
Attempting to connect to xx:xx:xx:xx:xx:xx
[CHG] Device xx:xx:xx:xx:xx:xx Connected: yes
Connection successful

Now type:

quit

I can't remember where I found the guide, but hopefully that will work for you too.

  • Tried that, but no joy for me. It is connected and trusted, but it won't move a thing :(

  • @Kazchen I read on another post that upgrading to 16.10 worked for them (albeit with a different Bluetooth keyboard!). If you are able to upgrade, this may be worth trying with yours? Jun 11, 2017 at 11:48
