A quick check of Microsoft Surface Dial specs confirms a thought I just had. It turns out the Dial is a Bluetooth LE (aka BLE) device, not a regular Bluetooth device.

This means slightly different scanning and connecting commands are required. For example, both "sudo" and "lescan" are required in the following to scan for BLE devices

Code:

sudo hcitool lescan

while the following can be used to connect to one with MAC address xx:xx:xx:xx:xx:xx

Code:

sudo gatttool -b xx:xx:xx:xx:xx:xx -l

Or something like that. I don't have a BLE device to test with. Google is your friend.
