What is the minimum Bluetooth version required?

Hi All,

I’m trying to connect the CyberBrick Destop app to the Cyberbrick Cores from an Intel based Mac. I can see the list of modules, I can select one, it starts blinking green, but if I click on continue, nothing seems to happening other than it stops blinking.
It does this for all the modules (so it’s not a hw issue) and everything works from an other windows computer.

Since it is an old Mac with only Bluetooth 4.0, I was wandering if that is the issue.
Any ideas?

Well searching seems to suspect its probably 4.2 but none of the official docs seems to state the version being used
