Airdrop doesn't work between MBP mid-2012 and iPhone 6

I read that Airdrop between iOS is since the MBP mid-2012. Although I have that Macbook I can't see my iPhone and viceversa. What can be the problem or the info that I'm misunderstanding?

PS: I have El Capitan but didn't make a clean installation.

Thanks in advance.


Found a post which gives this advice:

Turn off bluetooth on your mac, delete: /Library/Preferences/com.apple.Bluetooth.plist turn bluetooth back on

I tried this and can confirm that it fixed the problem for me.
