RE: Porting nrf52833 code on nrf5340

Hi Nicola,

The nRF5340 radio supports both AoA and AoD modes, and the SDK samples allow you to configure the device as a transmitter for AoA scenarios. It is capable of generating and transmitting CTE (Constant Tone Extension) packets as required for direction finding applications. Qualification here refers to the Bluetooth SIG qualification.. The nRF52833 is the SoC that is fully qualified for direction finding. The nRF5340 though has the same support for AoA as the nRf52833.

[quote user=""]In addition, if nrf5340 is good for above requirements , is there any limitation in using direction finding and BLE Audio profiles all together with such nrf5340dk board ? Can we use both functionalities in parallel?[/quote]

Yes, the nRF5340 can support both direction finding and LE Audio.. But, you will need to check if the memory consumption with both the features enabled would be enough as these are 2 large functions. Note that the SDC only supports AoA transmitter functionality: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/README.html
