R2 Pro Bluetooth Support

I have just updated RoastTime and was reading through the release notes. I can see there is a specific mention of Bluetooth support for R2. Does anyone know how this works and whether it provides wireless roaster control?

Communication Service : v3.32.0
“+ New Feature: Bluetooth v2 support for upgraded wireless roaster connections on R2”

My R2 Pro has the 159 firmware but I dont see any discoverable item on my Mac

Thanks
