airdrop not working with yosemite
I am trying to transfer a file from my MacBook air to my iPad. The MacBook air 2012 is running 10.10.1. The iPad air 2 is running 8.1.2. I turned on Airdrop on my iPad (everyone). Then I control clicked on a pdf in the finder on the Mac and chose share > Airdrop. I clicked on the icon for my iPad and it said "waiting." But nothing happened on my iPad. I tried it again and this time the icon for my iPad was not there. Any suggestions?
iPad Air, iOS 8.1.2, 64 GB, WiFi
