nRF5340 using Bluetooth BLE Audio

[Joe Black]

Hello to all :-)

i am not sure if this is an Hardware-topic, but i want to know the possibilities how to can

use and configure the nRF5340 (where can i find a detailled datasheet or ref-manual)?:

Is it possible to use this chip in the following configurations (and how to configure):

*) Dual Mode (BT EDR/BR and BTLE)

*) Dual eSCO

*) BT LE with CIS and BIS as initiator (Central)

*) BT LE Audio with CIS and BIS as initiator (Central)

BR,

Hi Johannes,

Are you using the nRF5340 Audio DK: https://www.nordicsemi.com/Products/Development-hardware/nRF5340-Audio-DK.?

I have this one ....

... (i am not sure, if this is functional the same ?) and also the smaller one, which you have posted!

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

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,

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,
