Maximum iso data length of NRF5340 audio increased

Hello,

I am using bis gateway on nrf5340 audio dk to transmit data.

In addition to audio encoded data, I also wanted to send some additional data, so I put these data after the audio encoded data and sent them together, and then I encountered the -EMSGSIZE error.

It seems that the maximum iso data length is 120, if the data length exceeds this size, it will not be transmitted.

Can this maximum length be increased?

  • Hi,

    Do you use nrf5340_audio application? Can you show your changes?

    Do you use I2S or USB?

    Can you provide a full error log?

    Best regards,
    Dejan

  • Yes, I use nrf5340_audio application, and I use USB in.

    Here are my changes, I increased the data length when sending it.

    [audio_system.c]

    static void encoder_thread(void *arg1, void *arg2, void *arg3)
    {
        ...
        if (sw_codec_cfg.encoder.enabled) {
    			/* Send encoded data over IPM */
    			//streamctrl_encoded_data_send(encoded_data, encoded_data_size);
    			streamctrl_encoded_data_send(my_data, 520);
    		}
    	STACK_USAGE_PRINT("encoder_thread", &encoder_thread_data);
    	}
    }

    And I added the max data related log to iso_chan_max_data_len function in iso.c.

    [iso.c]

    static uint16_t iso_chan_max_data_len(const struct bt_iso_chan *chan,
    				      uint32_t ts)
    {
    	...
    	/* Update the max_data_len to take the max_controller_data_len into account */
    	max_data_len = MIN(max_data_len, max_controller_data_len);
    	BT_INFO("Max data len:%d",max_data_len);
    	BT_INFO("Max Controller data len:%d",max_controller_data_len);
    
    	return max_data_len;
    }

    This is the config I added in prj.conf.

    CONFIG_BT_ISO_TX_MTU=2048
    CONFIG_BT_ISO_RX_MTU=2048

    Then this is my error log.

  • Hi,

    Which NCS version do you use?

    Can you show full log?

    Best regards,
    Dejan

  • The NCS version I use is v2.2.0.

    Here is the full log.

  • Now I already know how to increase the maximum iso data length, just change the codec configuration of bis gateway.

    It seems that the maximum value can only be changed up to 251 bytes.

    Here is my change in bis gateway.

    [le_audio.h]

    #define BT_AUDIO_LC3_BROADCAST_PRESET_RECOMMENDED(_loc, _stream_context)                           \
    	BT_AUDIO_LC3_PRESET(                                                                       \
    		BT_CODEC_LC3_CONFIG(                                                               \
    			BT_CODEC_CONFIG_LC3_FREQ_48KHZ, BT_CODEC_CONFIG_LC3_DURATION_10, _loc,     \
    			251u, 1, _stream_context),         \
    		BT_CODEC_LC3_QOS_10_UNFRAMED(251u, 4u,20u, LE_AUDIO_PRES_DELAY_US))

    But I encountered a new problem. When I tried to use bis headset to connect to the modified bis gateway, an Unexpected PA sync lost error occurred in bis headset.

    This is my modification in bis headset.

    [le_audio_bis_headset.c]

    static struct bt_codec codec_capabilities =
    	BT_CODEC_LC3_CONFIG(BT_CODEC_CONFIG_LC3_FREQ_48KHZ, \
    			    BT_CODEC_CONFIG_LC3_DURATION_10, BT_AUDIO_LOCATION_FRONT_LEFT|BT_AUDIO_LOCATION_FRONT_RIGHT, 251u, \
    			    1, BT_AUDIO_CONTEXT_TYPE_MEDIA);

    This is log.
