HI PSR,

Apologies for the lack of response so far.

Does your use-case require LE Audio, or do you want to get and play the PCM data on the same device?

For the LE Audio case, you can refer to the audio_system and audio_datapath files in nrf5340_audio/src/audio.

You can still refer to parts of the Audio application for the local case and use the unicast server or the broadcast sink. The CIS bidirectional walkie-talkie demo both records and plays audio: it records audio and transmits it to the peer device and it receives audio and plays it.

Best regards,

Maria

Hi Maria,

I'm currently working with PCM data from the nRF5340 DK and I want to play audio on the nRF5340 Audio board. Could you advise on which communication method I should use? Additionally, could you please provide any sample code for this?

Thank you!

[Maria Gilje]

You can transfer the data wired over I2S and wireless with LE Audio. We don't have a simple example which demonstrates this, but the nRF5340 Audio application uses both methods. PCM data is transfered over I2S from the CS47L63 to the nRF5340 on the nRF5340 Audio DK.

Hi Maria,

I have only one nRF5340 Audio DK board. Can it work with both a microphone (input) and a headset (output) for audio at a time?

Thank you!

Hi Maria,

I am receiving PCM hex data on the nRF5340 DK board.

Can I transfer this PCM data to the nRF5340 Audio DK?

Will I be able to get audio from the nRF5340 Audio DK?

Hi Maria,

could you please respond anyone as soon as possible.

I followed this link is  (Missing Forum Thread) 

The nRF5340 DK is configured as a unicast audio client, and the nRF5340 audio DK is set up as a headset. However, I'm unable to get the sample audio from audio dk board, having trouble setting the QoS.

Could you please verify the attached logs?
