Q: ipad air bluetooth can't find iPhone 5 and vice versa

Hi new iPad air and iPhone 5 both running 7.0.4 but can't find each other via bluetooth which is anoying as I use the iPhone as a hotspot so only needed a wifi iPad, the hotspot still works with my iPad2.

I've turned off iPad2 and also forgot device on iPhone, both iPhone and iPad air been turned off and on again, sat right next to each other on the desk and still now communication.

Any advice appreciated.
