What is a CBDevice?

It's something paired to your Mac over Bluetooth. Duet wifi?

 

[blackxacto]

What does "Duet" mean? Is that the application Duet, or, the bluetooth connection between computer and device?

 

[chabig]

I have no idea. I assumed it was the brand of wifi router you have, and that it made a bluetooth connection for management. Maybe someone else knows for sure.

Anyone think that CBDevice could be Canon Bluetooth Device [printer]? I have a wireless Canon printer.

CB stands for CoreBluetooth.

I guess it could be any Bluetooth device.

BDA is Bluetooth Device Address

Can you check the address of the Canon printer? Is it 70:EA:5A:8F:2E:29?

 

[blackxacto]

Jove, I will check, thanks for responding. Where do I find this address please?

I don't know. Maybe there's a label somewhere on the printer? Or check the network settings of the printer using the printer's control panel or remote UI.

FWIW, "70:EA:5A" is the OUI portion of the MAC address, registered to Apple in 2019, so it should be the Apple hardware/chipset, not a property of any associated peripheral. You can browse the Mac's MAC addresses and those of paired peripherals in the System Information tool, Hardware>Bluetooth, and Network>Wi-Fi.
