Good news!
What type of Bluetooth adapter are you using? I realise the motherboard has it built-in along with wifi, but only a few brands are fully compatible with macOS. Check System Report to see it it is recognised and if it is, what make. If there's nothing there you might need to buy a USB dongle as per the buyers guide.
"bluetooth is showing up in the System Report.
I've attached the bluetooth information report below. - to keep things simple - I may just go with the dongle.
I'm having problems with the GPU not performing well...at all. It's working, but thats about it. It is not smooth and it will not display anything when I'm trying to use Apple Maps. video is smooth unless enlarging to full screen.
I've also attached the system report for the display. I'm able to use the graphics card in my signature, but not getting any performance out of it at all.
This has been an adventure, but without walls help - there's no way I would have been able to get this done!
