Connecting two iPods
I am trying to connect an iPod touch (4th Gen; ios6.1.6) with an iPod touch (5th Gen; ios8.2) but they are not detecting each other. I have re-started both devices and reset the network settings. In both cases the result was the same and neither device could detect the other. Is there an incompatibility between Bluetooth 2.1 and 4.0? If not, what other options do I have to get them to detect each other?
iPod touch (4th generation), iOS 6.1.6
