About nRF5340 Audio operation

[Junichi]

What is the possible reason that LED1 blinks and LED2 does not light up when the nRF5340 Audio source is operating?

I have read and understood the source code, but I am not sure what causes the above phenomenon.

Hello,

LED1 blinks blue when the gateway is streaming, LED2 lights up when sync has been achieved. So the scenario where LED1 is blinking and LED2 is off is when the gateway is streaming and sync has not been achieved. See the LED overview here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/applications/nrf5340_audio/doc/user_interface.html#leds

Best regards,

Maria

What causes a gateway to be out of sync while streaming?

This will depend on your application mode and the stream parameters. You can get some information from the device logs.

Which NCS version are you using?

Which mode are you running the audio application in?

Best regards,

The version of ncs is 2.5.0.

It is running in release mode.

In debug mode, the following error occurs when building.

The error is as follows:

Do you get any errors or warnings before "-- Configuring incomplete, errors occurred!"? The last part is quite generic and I think the actual error is printed before in the build log.
