I am not able to locate airdrop from control center. I am using iphone 6 plus and ios 8.4

Don't have a clue about that, but...

"Dukto is a simple application that allows you to share files between devices connected to the same (wireless) LAN network."

Works for me.

Do you have it restricted?

As kb1951 suggests, check in Restrictions first. If it's not restricted try resetting your iPhone by holding the home button and lock button until you see the Apple logo. Check to see if it shows up after that.

Hi

Other device like Apple TV needs to be on before Air drop will show in control panel .

Cheers

I am nowhere near an Apple TV and the Airdrop icon is available in my control center. Even with wi-fi turned off you can still see the AirDrop icon.

Not correct. AirDrop will show even if you are nowhere near an Apple TV or another iOS device. If you are nowhere near any compatible Apple devices, they will simply not show when you select AirDrop.

Glad you found the problem. Sometimes we set these things then forget that we did and wonder why they don't work then.
