Im trying to host hotspot from my iphone 5 to a 4s via Bluetooth but cant seem to get it to work. The phones cant seem to see each other during BT pairing. (both phones have latest firmware) 

I can BT hot spot from my iphone 5 to my ipad 2 no problem but iPhone to iphone doesn't seem to work(is it even supported??)

I prefer using BT hotspot over wifi as BT doesn't thrash my battery and BT doesn't time out..
