Hello
I am experiencing two problems.
My development environment is STM32L072CZ-LRWAN1.
You are now using a combination of END_NODE and AT_SLAVE examples.
I'll sort out my problems.
The first is that 'SET' values are not operated through features such as AT+DEVEUI, AT+APPEUI, etc.
#define STATIC_DEVICE_EUI 0
Modified to above define to change settings.
but
AT+DEUI=11:22:33:44:55:66:77:88
AT_ERROR
As shown above, only errors continue to occur and do not change.
AT+DEUI=?
AT+DEUI?
The above 2 functions operate normally.
I will attach the serial output as a picture
The second is that once the MCU is reset, it stops working.
I'm currently using LPUART1.
Please advise how to solve this problem.

I found a solution for myself.
I'm posting it because I think there are people who are having the same problem as me.
Please check if the NVIC setting is not wrong.
In my case, I believe that the interrupts between SPI and GPIO collided during the interrupts of the pins that are commonly used with the SPI pins during the GPIO setup process.
