I got a reply from my colleague that he does not know any internal R&D groups working on BT Classic. All are with LE only.

Thanks for your reply. Yes I agree that long term BT classic will be replaced by BLE but we have to interact with todays mobile phones and support them for some more time. We understand Nordics strategy in this.

But yes please, any more information would be very appreciated. Are there examples of system designs or considerations to adhere to that can help us forward?

All of our products in Nordic are foccused on low power IoT use cases. So no, I do not think BT classic was every on table with our roadmaps as BT Classic is very power intensive protocol and do not suit low power IoT devices we cater to.

The use cases for BLE Audio are relatively new and atleast I haven't heard of any customer designs that are two chip solutions from different vendors. But it should be very straightforward design if both the SoCs have their own memories and radio components. The design becomes more complex when there are shared resources between two.

I have asked my colleague who have more insights in the BLE Audio part to see if he has any knowledge of use cases such as yours.
