Troubleshooting onboard bluetooth (MSI motherboard model H97I-AC)

I have the MSI H97I-AC motherboard which comes with bluetooth onboard "Wi-Fi 802.11ac, Bluetooth 4.0, Intel® Wireless Display" which does not work with bluez, at least in my hands.  I haven't experienced much relevant hits in google so I wanted to ask here.  Thoughts are welcomed.

% systemctl status bluetooth.service

I'm not sure how to go about identifying the hardware on the motherboard supplying the bluetooth 4.0 functionality.  I don't see anything relevant in `lspci -vvv` expect perhaps for the onboard wifi which is "Intel Corporation Wireless 7260" and uses the iwlwifi module.  I only mention that since the description of this hardware seems to indicate it is a bluetooth/wifi combo.

I do have some dmesg output relating to bluetooth but doesn't really point me in a direction:
