Ubuntu 15.04 Can't pair apple bluetooth keyboard

Question

I can't get my Apple Bluetooth keyboard to pair with Ubuntu 15.04. Does anyone have any idea how to fix this?

Solution 1

We will start by getting the firmware

wget https://www.dropbox.com/s/xbmm9vfg2fby2zn/fw-04ca_2006.hcd
sudo cp fw-04ca_2006.hcd /lib/firmware/brcm/BCM43142A0-04ca-2006.hcd
sudo modprobe -r btusb
sudo modprobe btusb

Then see if you can pair, if it doesn't pair edit question to include dmesg | tail from after the pairing attempt

Solution 2

This can be very frustrating, I had this problem with Ubuntu 16.04 and Apple Wireless Keyboard A1314 and got it working by trying with bluetoothctl with instructions from this bug report: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1490347 following: - agent on - default-agent - scan on // copy the device hardware address - pair <replace-with-hw-address> PIN code: #### <- type this on the apple keyboard Enter PIN Code: #### <- type this on the apple keyboard Pair successful..! quit

After successful pairing the num lock is on you need to press Fn+F6 to disable it.

Please edit the question to include results for `lsusb; dmesg | egrep -i 'blue|firm'
