According to About This Mac, I have "Apple Bluetooth Software Version 4.4.2f1 16391." Here's the report:

it also says that my iPhone has been acknowledged, but under the Services section it says:
Services:
Bluetooth File Transfer:
Folder other devices can browse: ~/Public
When receiving items: Accept all without warning
State: Disabled
Bluetooth File Exchange:
Folder for accepted items: ~/Downloads
When other items are accepted: Save to location
When receiving items: Accept all without warning
State: Disabled
Bluetooth Internet Sharing:
State: Disabled
So, why are all those services "Disabled?" I certainly didn't disable them deliberately, and I don't see anything in System Preferences to Enable them.
I do have an Apple BT Mouse connected and functioning, and a Bose Mini II Soundlink also paired and working.
On the iPhone, when I try to connect I get "Connection Unsuccessful, "MBP 17" is not supported" and a prompt to Forget Device, no other options. It pairs, but won't connect.
So, chas_m and chscag, what do you see as wrong? The MBP is an 8,3 17" Early-2011. OS X is 10.11.1.
EDIT: Oh, and AirDrop works between my wife's MBP and this one, as well as to her MacMini. It's just the iPhone that gives that error message. It's an iPhone 6.
