Moto. G bluetooth

AC Question

Had a moto g and it connected via Bluetooth to my headset, a taotronics.
Upgraded from the 4.5 inch (above) to the new 5 inch moto g 2nd gen. Unable to get the new phone to 'see' my headset. 4.5 phone still sees it OK. I switch the 4.5 off when I try to link my new phone.
Any ideas?
