Bluetooth 5.1 single mode

[mark.chang]

Hi sir,

I have a question for Bluetooth 5.1 single mode. As I know, above Bluetooth 4.0 has single mode and dual mode. Single mode only supports LE and dual mode supports LE and classical, is it right?

If the product only supports Bluetooth classical, could it be recognized as Bluetooth 5.1? 

thank you and best regards.

Nordic does not have any chips that support Bluetooth classic. We only support Bluetooth Low Energy (LE). 

The naming "Single and Dual mode" is not directly transferable to Bluetooth version. 

Regards,
Jonathan
