Re: Also consider Bluetooth
@Snowy, on your android device perhaps, but not on any of the (probably hundreds) I've seen used or supported over the years.
the only thing i've seen that comes close to that is some of the fitbit style things want BT and location on to do their "sync" thing and then they're perfectly happy without location.
This is only needed if you let the fitbit battery die for example. It will ask for location and bluetooth to sync but that's the fitbit app, not android, doing the asking.
