Help Keeping Bluetooth on?

[Pinmac1]

I used to have BT permanently switched on on my Note 1. It always showed in the bar at the top but only showed up in my battery stats if I actually used it. I was very happy with that as every time I got into my car it connected automatically via BT and I could pick up phone calls. I notied recently that it wasn't showing as connected in the car and realised that it wasn't on.

If I turn BT on, it turns off automatically after 3 minutes. I have looked in BT settings but can't see anything that causes this. I have an app called BT Auto Connect which doesn't seem to be the cause (don't want to test by uninstalling as I have it paired with so many devices).

Does anyone have any thoughts as to what I might have changed to cause BT to keep turning off please?

Doh! I've been struggling with this for a few weeks but within a minute of posting here I realised what the problem was! I had accidentally enabled a Tasker profile which automatically turns off BT after 3 minutes as I kept leaving it on after taking off my BT headphones. I've disabled it and all's well again. Phew!
