[jettoo]

Hello

nRF5340-audio-DK, NCS2.0.2, VScode

press BUTTON_VOLUME_UP then button reset,can't change to channel right.

    if (CONFIG_AUDIO_DEV == HEADSET) {

        ret=channel_assignment_set(AUDIO_CHANNEL_RIGHT);

        if(ret)printk("set channel right err:%d\n",ret);

    }

change to channel right failed, return -30

  

another question,  5340-audio can DFU?

  

Best regards

Hi 

Did you make any changes to the sample, or are you experiencing issues straight out of the box?

Are you sure that both the left and right channels are being sent from somewhere?

another question,  5340-audio can DFU?

Yes, this is possible. You can read more about the DFU support here.

Hi 

Fortunately proper DFU support was added in version 2.1.0 of the nRF Connect SDK. You can read more about this here.

This is work in progress, yes. There is no schedule for it right now, but hopefully we will have more information about this soon.

The codec supports it already, but currently it is not very easy to change from the application side. There is a pull request in the works to simplify this process, you can check it out here.

thanks for reply,

Hi

In order to change between headset and gateway you can set CONFIG_AUDIO_DEV in your prj.conf file. 

Set it to 1 for headset and 2 for gateway, as described in the Kconfig file:

config AUDIO_DEV
	int "Select which device type to compile for. 1=HEADSET or 2=GATEWAY"
	range 1 2
	default 1
	help
	  Setting this variable to 1 selects that the project is compiled
	  as a HEADSET device.
	  Setting to 2 will compile as a GATEWAY.
