There's a script to this on the gentoo wiki via BlueZ.

I personally think the problem with this approach is that most phones have 
bluetooth enabled explicitly as an option, it doesn't run all the time, or 
default on. Primarily this is because bluetooth can drain your phone's 
battery (though, I don't know by how much, if you're not actually 
transferring data over it).

A CR2032 cell, in a specific piece of kit, is going to last for a lot longer 
than a phone battery.
