Airdrop is not working

I have MacBook Pro mid 2014 with El Capitan and iPhone 6 Plus and 6s Plus with IOS 9.0.2

From both of them is impossible to send photos, no of both appeared in Finder - Airdrop.

In iPhone 6 were problems earlier - sometimes. But last one month it is not possible to connect.

I have settings OK, all has Bluetooth and WiFi ON, allowed for everyone.

In Mac was made renstalling and iPhone 6s set as new. Any advise?

Thanks guys.
