A couple of updates...

 - I've verified that the keyboard is indeed a low-energy device.

 - I'm able to see the device on my MacAir running 15.10 + the latest
5.37 bluez packages both in the indicator, and via bluetoothctl

 - I cannot successfully pair with the device from the indicator or
bluetoothctl

 - At some point, 'bluetoothctl info' shows that the device is paired &
connected, however the keyboard BT indicator is still blinking, which
means the keyboard is still in pairing mode, and it cannot be used.

 - When I attempt to connect using gattool, I get the following error:

Attempting to connect to DF:08:A9:A0:13:92
Error: connect error: Transport endpoint is not connected (107)

I also see the following error messages in my syslog:

Jan 25 12:06:24 shrike bluetoothd[949]: Unable to register GATT service with handle 0x0046 for device DF:08:A9:A0:13:92

Jan 25 12:06:25 shrike bluetoothd[949]: Read Report Reference descriptor failed: Attribute requires authentication before read/write

 - I was able to use the device with my new iMac, which is running El
Capitan.  When I pair the keyboard, I'm prompted for a PIN code.

So, it looks like PIN authentication isn't being handled properly for
this keyboard.
