Hi Johannes,

None of our devices support Bluetooth Classic (BT EDR), so it is not possible to do the 'dual mode'.. You can have both CIS and BIS concurrently, but there is no support for that in the reference example as of right now, so you will have had to modify the example to accommodate this..

Best Regards,

Swathy

Hi Swathy,

ok, thanks for the link, but there are also some questions which are not answered/described by the README-page:

*) Enhanced SCO (eSCO) - i found only one hit with the search function for the eSCO:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/softdevice_controller/doc/api.html?highlight=esco

But i want to know if the available HW- and SW will support the "Dual eSCO" !?

--> are there special settings to know (SW/HW-setup) or to take notice about?

*) And it's not mentioned, if the "Dual Mode" (BT EDR/BR and BT LE) is possible!

I know that the BT 4.0 spec. permits devices to implement either or both of the LE and BR/EDR systems, but is this out-of the box possible?

--> is this possible on this HW (SoC)?

--> Do we need a second antenna? (no frequency multiplexing)?

--> Are there any source examples available with such a setup?

Thanks in advance!

BR,

Johannes

Hi Johannes,

The nRF5340 Audio DK is the one that is designed specifically for LE Audio application.. You could take a look at our documentation for LE Audio application here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html
