EC25 AFX at+qprtpara=4 returns ERROR

HI

I am using EC25 AFX and would like to use command at+qprtpara=4.But I found that it may return ERROR and you cannot get OK until the LTE reboots.
Any commands need to be called before calling at+qprtpara=4 to make sure it can return OK?
Thanks.

hi there
AT+QPRTPARA=4 can read the number of CEFS file system restores and the number of bad blocks in the efs partition. You can query it 5 seconds after the module is turned on, or you can restart the module, thank you.
