RE: sd card on nrf5340 audio dk

Hi,

Please note that the application that you tried to use earlier does not have the same goal as what you want to achieve. That application was made for playback of the audio file which was previously stored on the SD card.

As mentioned previously, we do not have any samples which can show how storing to the SD card can be done. We can provide general direction, but implementation details are up to you. In general, you can look at sd_card.h for API. If you want PCM/WAV file stored, you can write to the SD card after data has been decoded using sw_codec_decode().

Edit: You can also refer to this pull request that adds the ability to save wav recording.

Best regards,
Dejan

Hi,

You could try to write LC3 directly to the flash or decode it to WAV first and store it using the API found in the src/modules/sd_card.c.

Best regards,

Also,

C:\NCSsemi\v2.6.0\nrf\applications\nrf5340_audio\src\modules\sd_card.c and sd_card_playback.c exists.

Our concern :

Kindly help out with a possible workaround to save the audio data received on audio dk in the sd card.

Hi,

Could you provide full build log which shows the error?

[quote user="Ridhi"]Also, i found that in \v2.6.0\nrf\applications\nrf5340_audio\src\modules there are functions for sd card but how to use them in a way that they can save BLE data.[/quote]

Which functions do you refer to?

Best regards,
Dejan
