Does it work by manually using bluetoothctl as root and using "power on" from that command prompt? You'll need bluez-utils from [extra]. Supposedly there's also new kernel firmware available for this BT chip (read that on the Ubuntu posting).

bluetoothctl opens a prompt but accepts no input. I've placed the firmware files from git://git.marvell.com/mwifiex-firmware.git using https://github.com/nuclearsandwich/mwifiex-firmware-git

Bluetooth and the pen work fine after installing the Marvell driver from Git. Please update the checklist.

@vistaus I'm still having bluetooth issues with the latest firmware. Any suggestions for how to debug. I'm not a regular user of bluetooth but would love to get some bluetooth keyboards working.

As of http://git.marvell.com/?p=mwifiex-firmware.git;a=commit;h=feb42c90e24f1aaa190e2d423b0f6fc06beb81f6 bluetooth appears to be working (and wifi much stabler) with 3.18.3 Manjaro kernel. I've got lvm set up to try and get parity between this Manjaro install and my archlinux installation.

I was getting pretty disappointed with everyone else havworking on kernel 3.16ing Bluetooth success while I was left out. It seems to work fine in this Manjaro prerelease I installed for fun. I'm typing this on a bluetooth Thinkpad keyboard. Next step: Get the keyboard working in the initramfs so I can enter my disk encryption password with it... or just keep the type cover handy with 3.19

Bluetooth seems to have issues when running for long periods of time. If a device disconnects it doesn't seem to want to reconnect.
