Hi,

[quote user="tourists"]Sorry, I didn't express myself well. The error happened when I flashed two core with two .hex files. When i merged two .hex files and flashed, the error did not appear.[/quote]

Ah, I understand. That makes sense, since you need to flash the device with the merged hex. https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/nrf/config_and_build/configuring_app/output_build_files.html talks more about the build file output and what the various files are.

Try CONFIG_LC3_DEC_SAMPLE_RATE_48KHZ_SUPPORT=y

Kind regards,
Andreas

[quote userid="107683" url="~/f/nordic-q-a/118791/re-case-id-339247-ncs-2-7-0/522234"]I'm not sure if I quite understand what you did when you only flashed (burned) one core? You always have to flash both cores AFAIK for an Audio application[/quote]

I used this cfg but get the same problem.

#
# Decoder sample rates
#
CONFIG_LC3_DEC_SAMPLE_RATE_8KHZ_SUPPORT=y
CONFIG_LC3_DEC_SAMPLE_RATE_16KHZ_SUPPORT=y
CONFIG_LC3_DEC_SAMPLE_RATE_24KHZ_SUPPORT=y
CONFIG_LC3_DEC_SAMPLE_RATE_32KHZ_SUPPORT=n
CONFIG_LC3_DEC_SAMPLE_RATE_441KHZ_SUPPORT=n
CONFIG_LC3_DEC_SAMPLE_RATE_48KHZ_SUPPORT=n

I have another 5340, can i use it to verifie the problem?

Could you please give me guidance on how to complete it?

Thanks!

Hi,

48kHZ and 2x 24kHZ should be fine according to what I find. I can't find anything w.r.t Galaxy buds supporting 16k og 8k, meaning that you won't be able to set up the codec if you don't support the Galaxy buds supported rates

[quote user=""]This case don't happen when i merged net_core and app_core to burn. I used to burn only one core.[/quote]

It can establish tow 48k encode streams and two 24k decode streams when set CONFIG_STREAM_BIDIRECTIONAL=y .I think It can support,

Hi,

Have you verified that the Galaxy buds supports lower than 48kHZ rate?

Kind regards,
