Hello Dejan,

I would like to express my heartfelt thanks for all the support you have provided throughout this ticket. With your assistance, I was able to achieve the desired configuration with the DK, and I am looking forward to testing it further with my PCB.

Once again, thank you so much!

Best regards

Good mrning Dejans,

I would like to express my thanks again. I was able to configure CIS Stereo mode using the v2.6.2 SDK by following this article and making some modifications to my code.

While attempting to achieve a bidirectional configuration by enabling CONFIG_STREAM_BIDIRECTIONAL=y to get input from the microphone, I encountered the following error from the headset: (Left)

The line 399 in audio_system is:

I have tried several methods to change the number of data channels to 2, but none of them have worked. Could you please assist me with this issue?

I would like to mention that with the current working SDK I am using, both headsets are connected and synchronized, but there is no sound coming from the right headset. the log file of the right headset with out enabling CONFIG_STREAM_BIDIRECTIONAL=y, when the left one output sound:

RE: Issue with Stereo Sound from External Codec on nRF5340 DK (SDK v2.6.2)

dejans — Wed, 27 Nov 2024 17:12:24 GMT

Hi Abdulmohaimen,

The error "<err> sw_codec_select: Unsupported channel mode for decoder: 0" in your NCS v2.6.2 log indicates that channel mode for decoder is not properly selected.

You can look at m_config.decoder.channel_mode, struct sw_codec_decoder and enum sw_codec_channel_mode for the place where channel_mode is set. This is how sw_codec_channel_mode looks like in sw_codec_select.h

enum sw_codec_channel_mode {
	SW_CODEC_MONO = 1,
	SW_CODEC_STEREO,
};

You could try to check how m_config.decoder.channel_mode is set.

Best regards,
Dejan

Hi Abdulmohaimen,

Are these logs in NCS v2.6.2 obtained after you implemented the same code changes as when you used NCS v2.4.2?

RE: Issue with Stereo Sound from External Codec on nRF5340 DK (SDK v2.6.2)

Abdulmohaimen — Wed, 27 Nov 2024 12:05:04 GMT

Hey Dejans,

While working with v2.6.2, I encountered some recurring errors.

I found the mentioned code of v2.4.2 from a previous ticket , implemented it, and it worked, allowing me to achieve CIS audio, albeit with limitations, as previously mentioned.

My approach was to continue working with the functional setup on v2.4.2 to find a concrete solution and resolve all potential problems. After that, I plan to update and attempt to achieve the same results with the newer SDK.

Best regards

Abdulmohaimen

Hi Abdulmohaimen,

In your initial post you mentioned NCS v2.6.2 but you showed the log when using NCS v2.4.2. Can you provide clarification on the NCS version you currently use?

Best regards,
Dejan

Hey Dejans,

I have been using the older SDK because it is the only version with which I have made progress so far. I currently have no issue with transitioning to a newer SDK. However, as I mentioned before, I was unable to make further progress with version 2.6.2.

I would be grateful if you could provide me with any steps or guidance to move forward with the new SDK and address potential issues, such as pairing and data rate problems.

Thanks in advance.

best regards

Abdulmohaimen

Hi Abdulmohaimen,

Would it be possible that you switch to newer NCS version sooner rather than later? The controller that was used in audio application before NCS v2.6.0 is deprecated and it is highly recommended that you update your NCS version. The most recent NCS version in 2.8.0.

Best regards,
Dejan

I forgot to mention that I am not using the configuration CONFIG_AUDIO_SOURCE_I2S=y, as my source is via USB. However, I am experiencing some issues with the microphone—when I use it, I only hear a noisy signal.

Hey Dejans,

Thank you for your support, and I apologize for the delay. I have been working hard to resolve the issue.

I have tried the provided code, but unfortunately, it does not work.

I also tested the code mentioned in this tickt, and I was able to achieve stereo sound with CIS. However, there are some limitations, such as only one data channel (left) being transmitted

One of the problems I am currently facing is that the gateway cannot reconnect to the headset after it has been turned off. To re-establish the connection, I have to press the reset button.

I would now like to achieve a stable CIS connection with both channels (left and right) being transmitted. After that, I aim to implement it using a newer SDK version (I am currently using v2.4.2).

I have tried the approach mentioned in this tickt, but when I add CONFIG_BT_MAX_CONN=2_ to the prj.conf file, I encounter the following error from the gateway:

Hi Abdulmohaimen,

You could try to debug your application using tools mentioned in debugging lesson in the nRF Connect SDK Intermediate course.

I have added the necessary Kconfig option to the prj.conf file. However, once the Bluetooth connection starts, the following error occurs:

I would like to mention again that my goal is to achieve walkie-talkie-style stereo sound with headsets connected to the DA7212 hardware codec. Before making the modifications, I was able to hear mono sound from the external codec.

Could you please assist in resolving this issue?

Thanks in advance

Hi Abdulmohaimen,

If your server needs to decode 2 channels, please try adding Kconfig option - CONFIG_LC3_DEC_CHAN_MAX=2.

Hi,

You could have a look at these potentially relevant discussions - stereo output using external codec and stream multiple stereo audio. If these links do not provide you with relevant information and that is not what you try to achieve, please provide more information about your use case.

Hi Dejan,

I am using three nRF5340 DKs—one as a gateway and two as headsets (Left and Right). Both headsets are configured to connect to the DA7212 external codec. However, I am only hearing mono sound from the headsets instead of stereo.

Could you please provide further assistance on how to enable stereo sound in this setup?

Hi,

Thank you for your swift reply.

I am using the DA7212 evaluation board, and I can hear sound from the jacks on the DA7212 board. I followed the instructions from Nordic to enable the external codec.

However, I am still working on achieving stereo sound, as the current output is mono. Any further guidance would be greatly appreciated.
