Ubuntu – Bluetooth keyboard paired but not responding 16.04

16.04bluetoothkde5keyboard

I'm running ubuntu 16.04 and I'm trying to pair my Microsoft Designer Keyboard to my computer.
When I try to pair it, the GUI ask me to enter the pin code on my bluetooth keyboard and press enter.

Ubuntu says that my keyboard is paired but it doesn't seems to work. My keyboard led continues to blink like it was searching to pair.

The strange thing is that Ubuntu detect if submitted pin is correct or not.
I tried many things like doing pairing with bluetoothctl command but nothing change. I also had issues to connect my "Microsoft designer mouse" but I managed to solve the problem.

Here is my /var/lib/bluetooth/@pcbtmac/@keyboardsmac/info file:

Updating to 16.10 fixed this problem for me. I did have to reboot after pairing for some reason, but it's been working fine since then.

I know that's not a solution for 16.04, but it does confirm again that this keyboard can work under Linux.

Ubuntu – Apple wireless keyboard pairs but won’t connect in 15.10

This was a pain in the button to get working. I really wanted to make a precise answer but I think the tech is a little flaky and the tools are a little trying. I did it once successfully, went to do it again from my notes to make sure my answer was sound and it took me another hour of trying to get it to take. These are the steps I followed on Ubuntu 16.04 (derived from @phireph0x and @danielfbm's answers).

Install bluetoothctl:
```
 sudo apt install bluetoothctl
```
Run bluetoothctl. You should see an initial list of connected devices like so:
```
[NEW] Controller 23:34:17:64:AF:0E ChromeLinux_A00F [default]
[NEW] Device 00:19:32:D3:38:01 Pico the Keyboard
```
It's ok if you don't see the Apple keyboard initially. You should see it by the end of step 5 in the next section.

The remaining steps are from the bluetoothctl command prompt:

Set the agent:
```
agent KeyboardDisplay
default-agent
```
Turn off the Bluetooth keyboard by removing the batteries. Hold the power button in and wait 10 seconds.
Scan for devices: scan on.
Turn on the Bluetooth keyboard by reinserting the batteries holding the power button in for 10 seconds. If you don't see the keyboard power light blinking continuously, it's not trying to pair. Try again.
Wait for your Bluetooth keyboard to appear in bluetoothctl. This will happen asynchronously while you wait at the prompt. My keyboard popped up after 20-30 seconds.
Remove any previous attempts: remove 00:19:32:D3:38:01. Replace 00:19:32:D3:38:01 with your keyboard that popped up in step 5.
Wait for your Bluetooth keyboard to pop up again. This will probably take 20-30 seconds.
Make a connection and pair the Bluetooth keyboard: connect 00:19:32:D3:38:01. Replace 00:19:32:D3:38:01 with your keyboard that popped up in step 5 and 7.
If you're on track, you should see your prompt change from: [bluetooth]# to [Pico the keyboard]: .
Now, on your Bluetooth keyboard, type 1234 and press enter. That's five keystrokes on the Bluetooth keyboard: 1, 2, 3, 4, and the carriage return.
If that worked, you should see the prompt change to:
```
[agent] Enter the pin code:
```
On your other keyboard, not your Bluetooth keyboard, type 1234 and press enter.

If all works well, you should see Connection successful. If the connection failed, turn off the keyboard and try again from step 2.

Troubleshooting:

The keyboard seems to mate for life and will try to pair with any Macs it has paired with in the past. Make sure they're off.
Restart your PC if all else fails. I was surprised to find that I didn't seem to have much trouble with the Ubuntu Bluetooth stack. I did restart a couple times but I don't think it's what got things working in the end.

Ubuntu – Bluetooth paired but not connected ubuntu 16.04

I did what Bradyn Claycomb suggested but it was not enough so I improved it as follows:

sudo apt install pulseaudio-module-bluetooth 
pulseaudio -k
pulseaudio --start

Then I can connect to my Bluetooth headphone from Ubuntu 16.04
