Bluetooth timeout?
 

I have noticed sometimes, i always leave bluetooth on, that i go to put on my headset or gps and it wont connect, then i go check and my bluetooth is either off, or it says its on, but when i click it i changes to off like the icon was faked out and then turns on. does the bluetooth go into sleep mode or have some kind of power save feature were it turns off if not connected in say an hour? thanks!

I am still running a 2.X rom and I find that some GPS apps crash the bluetooth stack if you put the device to sleep or turn off the GPS while the app is still running.

Also almost as soon as the low batt notice fires the device will kill bluetooth to save power.

Pairing also doesn't seem to work while the device is asleep so always make sure it is on before turning on your bluetooth device, once connected you can sleep your PPC again.
