Senior moment (old git) bluetooth no device found

[fuzzylogic]

Breaks out my shield and gets ready for the flac

 

I deleted a line out of the root which was associated with my Bluetooth device

sadly like all things I now realize I shouldn't have done that tried to find the deleted line and well, was not able to.

I now have no Bluetooth devices even when I plug in different usb Bluetooth dongles.

so my question to those with more  wisdom is :- is it possible to extract the missing line from the Mojave installer and re install it

or is it a re install only?

I am not too concerned if it is a re install, we all learn and even an old git like me still learns. I did try x code Bluetooth to re install that way

but for some reason it did not work.

remember go easy you will be an old git one day

thanks and waits for the stick
