Q: bluetooth not working

Transferring data between an iPod nano and an iPhone is not supported.

To share content with AirDrop, both people need one of these devices using iOS 7 or later, or a Mac with OS X Yosemite or later:

• iPhone 5 or later
• iPad Pro
• iPad (4th generation) or later
• iPad mini or later
• iPod touch (5th generation) or later

You also need to turn on Wi-Fi and Bluetooth. If you want to share with your contacts, sign in to iCloud.
