Hello,
I have a test board with BG96 module on which I ran my program successfully. After some time, I made my own hardware and flashed the same firmware on the new module with QFlash.
During the test in my hardware, I get +CME ERROR: 23 (for a test command AT+CGSN) and +CME ERROR: 0 with AT+CFUN=1.
I know that +CME ERROR: 0 is related to Phone failure and +CME ERROR: 23 is related to Memory failure. But I don’t know how this error occurred and how should I fix it?
This is the terminal content:

Thanks for any help
