return error when press BUTTON_0 on ble_app_uart project

This post explains what happens in system off mode in debug mode. The reason ble_app_uart crashes when you set it to sleep in debug mode is that the emulated system off goes into a loop within the UART files in the SDK which I assume conflicts with the UART application and causes the error you're experiencing. The sleep function works just fine in normal mode.

Best regards,

Simon

My description may not be very exactly . Please check the blow snapshot :

In my opinion, it may not be the right behavior :

1. In ble_app_bps project, the same error can't occur when pressing BUTTON_0.

2. in ble_app_uart project, the same error can't occur when pressing other buttons.

So what error, exactly, does it pop up?

Presumably, this is an error from your IDE ?

If you're on Windows, you can capture a screenshot of the current window - eg, the error message - by pressing Alt+PrintScreen.

So that puts the CPU to sleep.

Putting the CPU to sleep will make the debugger lose its connection to the target; so what you describe sounds like expected behaviour - not an error at all?
