Hi Terry2,

Just follow up on the fix that I mentioned in my last reply. It seems that it is not in NCS v2.3.0 or NCS latest development downstream yet.

It looks like the fix is not dependent on anything, so if you encounter a problem with Bluetooth behavior while build with debug options, you could try cherry picking the commit to your current NCS setup.

Hi Terry2,

It looks like you are building with debug options enabled. With that, the stack use will be higher than what is being set in prj.conf.

I could reproduce your exact issue when I build with debug options. I tried to double the stack size and the sample now works.

Please try the following Kconfig when you build that sample with debug options:

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096
CONFIG_BT_RX_STACK_SIZE=4300

This was not necessary this time, but another stack that usually has problem when building with debug options is the main stack. That is configured by CONFIG_MAIN_STACK_SIZE.

Please watch out for any unexpected behavior when testing application built with debug options. There is also an issue in the BT stack size tracked here. It affects NCS v2.1.x and v2.2.0 to my knowledge. A solution has been added to the Zephyr upstream in this PR, but I am not certain if it has been fixed in v2.3.0 yet. I will get back to you regarding that soon.
