Hi all, could someone help enlighten me to what the different fields returned from the AT!IMAGE? command are? I am using a EM7455 module. I like to know what LRU, FAILURES and the difference between UNIQUE_ID and BUILD_ID.
Also is there a AT command to select the firmware to use without changing the PRI file? Right now I know of only using AT!IMPREF=“xyz” command to pick based on carrier name. This changes both the firmware and the PRI file, right?
Also yesterday used the AT!IMPREF=“ATT” command to change the preferred image from GENERIC to ATT. After doing a at+cfun=1,1 command to reset the module, I do see ATT in both the preferred and current when doing a AT!IMPREF? command.
But then I did a AT!IMPREF=GENERIC to change it back to GENERIC. After doing the same module reset, I see GENERIC as preferred, and ATT as current. There is also 2 lines in AT!PIMPREF? that says something about name mismatch.
Then today after I got into the office and powered up the module and did a AT!IMPREF? again, I see preferred and current both as GENERIC. Strange!
Anyone has a clue why the current stayed at ATT yesterday and today it is GENERIC?
Thanks a lot!
