Matter Light Bulb sample will crash on connection when CONFIG_SERIAL is enabled

I change the logging to use below config parameters:

# Config logger

CONFIG_LOG=y

CONFIG_MATTER_LOG_LEVEL_DBG=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_RTT_CONSOLE=y

CONFIG_UART_CONSOLE=n

That makes both the RTT logging and serial comms to work.

I also increase the CONFIG_BT_RX_STACK_SIZE from 1200 to 2400 just in case

Hi,

The log indicated that the BT RX thread caused the fault.

Could you check the value of CONFIG_BT_RX_STACK_SIZE in the.config file under build/zephyr and try to increase the value?

Regards,
Amanda H.

Follow up:

If only adding and no more changes than the line below, the device will not crash.

# Config UART

CONFIG_SERIAL=y

I wonder. Is there a conflict between activating matter logs and a serial port?
