5340 audio change to right channel

[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,

thanks for reply,

1.not change the sample code, only to know how to change channels dynamicy in code.

   

2.form the link,i don' konw how to add DFU, is there have examples for it?

i konw hello_world project add DFU like follow:

#include <mgmt/mcumgr/smp_bt.h>

#include "os_mgmt/os_mgmt.h"

#include "img_mgmt/img_mgmt.h"

void ota()

{

    os_mgmt_register_group();

    img_mgmt_register_group();

    smp_bt_register();

    int err = bt_enable(NULL);

    if (err) {

        printk("Bluetooth init failed (err %d)\n", err);

        return;

    }

    if (IS_ENABLED(CONFIG_SETTINGS)) {

        settings_load();

    }

    err = bt_le_adv_start(BT_LE_ADV_CONN, upad, ARRAY_SIZE(upad),upsd, ARRAY_SIZE(upsd));

    if (err) {

        printk("Advertising failed to start (err %d)\n", err);

        return;

    }

}

Hi 

1) The reason you can't change the channel assignment at run time is that this is statically configured through the UICR. In order for the run time selection to work you need to clear the UICR configuration. 

The easiest way to change this if you are flashing new kits is to change it in nrf5340_audio_dk_devices.json in nrf5340_audio\tools\buildprog

2) I don't think we have a complete example showing how to do DFU with LE Audio, no, but I will double check this and get back to you.

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.

Hi

thanks for reply,

i've update v2.1.0,  it can see dfu folder.

there will no overlay-gateway.conf and overlay-headset.conf

  

Best regards

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.
