I have a new Nexus 6P but cannot get my X5 to connect to

I have a new Nexus 6P but cannot get my X5 to connect to it via Bluetooth. Any ideas?

Are you running Nougat on that 6P?
Nougat has done some strange things to the BT4 stack, my Omate Rise (and my X3) will not connect either.

Yes I am thanks.
I did get it working but have since found that my Nexus is faulty with random reboots. Done all the checks and EE have said it is faulty. Problem is they don’t have any in stock and it is no longer on their website. I have been offered a LG G5 but I don’t really want it so am a bit stuck.
