There is a problem sending auracast

[chelalv]

I use nRF5340 audio DK,iso_time_sync example, can successfully send BIS data, then I use DK as controller, bumble(google.github.io/.../index.html) as host and it fails to send.

 I don't understand what went wrong. Can you give me some advice?

Here is the entire log

Hi, 

You could build the hci_uart sample with EXTRA_CONF_FILE='debug.conf' and connect the net core via RTT to check if it works as expected. You could also capture HCI packets in Wireshark and provide the output PCAP file to help investigate the issue.

Hi, Sorry for the late reply.
I don't know how to do this: build the hci_uart sample with EXTRA_CONF_FILE='debug.conf' and connect the net core via RTT to check if it works as expected.
I recompiled the hci uart example according to docs.nordicsemi.com/.../hci_logger.html
But when I use bumble to test, It looks like there is a problem with hci communication

I enabled Monitor protocol over UART, so prj.conf will increase CONFIG_BT_DEBUG_MONITOR_UART=y and reduce CONFIG_CONSOLE=n.

CONFIG_STDOUT_CONSOLE=n
CONFIG_UART_CONSOLE=n
CONFIG_GPIO=y
CONFIG_SERIAL=y
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_BT=y
CONFIG_BT_HCI_RAW=y
CONFIG_BT_HCI_RAW_H4=y
CONFIG_BT_HCI_RAW_H4_ENABLE=y
CONFIG_BT_BUF_ACL_RX_SIZE=255
CONFIG_BT_BUF_CMD_TX_SIZE=255
CONFIG_BT_BUF_EVT_DISCARDABLE_SIZE=255
CONFIG_BT_CTLR_ASSERT_HANDLER=y
CONFIG_BT_MAX_CONN=16
CONFIG_BT_CTLR_DTM_HCI=y

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=512

# Workaround: Unable to allocate command buffer when using K_NO_WAIT since
# Host number of completed commands does not follow normal flow control.
CONFIG_BT_BUF_CMD_TX_COUNT=10

CONFIG_BT_DEBUG_MONITOR_UART=y

Another question: Why can other programs sysbuild compile two hex, one application mcu and one network mcu, but hci uart only has one application mcu?

It appears that Bumble is attempting to initialize the controller, but is receiving invalid responses. Does the hci_uart work as expected?

Do you get the same result if testing with the NCS v3.0.2 iso_time_sync sample?

There is no multi-image build config to support that combination.

Hi Amanda, I don't quite understand this question: "Does the hci_uart work as expected?" 

I can run the iso_time_sync example on the nRF5340 audioDK without issue. 

I have some doubts whether the combination of hci_uart as net core and empty_app_core as app core can work properly. 

You can see my original question, I use hci uart as app core, the net core image of other examples， the controller is responsive.

According to the figure, it shows the controller doesn't support "creating BIG".

Probably you just use the default setting of the controller configs. 

You can refer to the configs used in the audio project:

https://github.com/nrfconnect/sdk-nrf/blob/v3.0.2/applications/nrf5340_audio/sysbuild/ipc_radio/prj.conf

Since the default one for hci_uart might not enable LE audio-related features.
