My iPhone 6 and my iPad Air2 are not visible to each other via Bluetooth

iPhones and iPads are not designed to pair with each other or with a computer via Bluetooth except for personal hotspot. More information: Bluetooth: Why can't I pair my iPhone or iPad with my computer?

Continuity does use Bluetooth but the devices aren't paired. If you are trying to use Continuity, the following may help: Get help using Continuity with iOS 8 and OS X Yosemite - Apple Support

Fox, I have a similar problem but not quite the same one. I have an iPhone 6 factory unlocked to be able to keep my current phone number on an AWS network which only supports 3G but has unlimited data. And I also have an iPad Air 2 on a Data-only plan with a different carrier that supports LTE.

I can hotspot via WiFi from both devices just fine:

[iPad as client] --wifi--> [iPhone as hotspot] --3G Connection--> [Internet]

[iPhone as client] --wifi--> [iPad as hotspot] --LTE Connection--> [Internet]

Now I hardly ever use the first option above, because obviously of the significantly slower speed. But my issue lies with the bluetooth. Because THIS works:

[iPad as client] --Bluetooth--> [iPhone as hotspot] --3G Connection--> [Internet]

But what I would ideally like is to have this:

[iPhone as client] --Bluetooth--> [iPad as hotspot] --LTE Connection--> [Internet]

Any thoughts? Any wisdom or insight on this from anyone would be greatly appreciated.

Thanks! :-)

My only thought is that it might be due to the different carrier -- not all carrier plans allow you to use a device as a hotspot. If that isn't the reason, you may want to start a new discussion here with a title that more exactly describes the problem you are having.
