Apple present Core Bluetooth support for BR/EDR devices at WWDC 19: «This now will allow transparent use of GATT with the BR/EDR devices»

But I can’t understand how we can use the GATT profile while interacting with BR/EDR devices. BR/EDR devices use the SPP protocol, so how can we access to services or at least get notify while connection?

Apple schematically showed the merger of two layers (for classic and ble), but nowhere is it explained what is meant. It is only shown schematically that we can connect to BR/EDR device using CoreBluetooth. But how can this be implemented in practice? Apple’s sample requires knowing the UUID of services from classic bluetooth or UUID peripheral. I know only Major Service classes of device.

Pls help and thanks in advance
