Unable to pair my macbook on iphone 6 via bluetooth

For sharing mac's internet connection with iphone for example....

"For sharing mac's internet connection with iphone for example...."

You don't use the regular Bluetooth pairing to share an internet connection.

Ok then which Bluetooth pairing is required, cuz am aware of just one...?????

System prefs > Sharing.

Select Internet Sharing (but don’t click the box to the left).

Select Share you connection from: Ethernet and tick Bluetooth PAN (Personal Area Network) in the box below.

Then click the box to the left.

Now open Bluetooth in system prefs.

On your iPhone, open Bluetooth and your iPhone should show up in Bluetooth prefs on your Mac.
Select it and you will be asked to verify a 6 digit code to complete the pairing.

Note that Internet sharing is NOT the same as paring with bluetooth to transfer data between devices.

Yes mate i know and i did that 100 times, am telling you that after that digit code it disconnects amd thats it....
