I-CUBE-LRWAN AT_SLAVE example AT_DevEUI_set

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.
