Dear all;

We have mc39i gsm modules and most of them send the same " EXIT: 740F 08 00 EEFULL" message right after i turn on the modules  using ignition line. Also all the modules which send this message do not respond to any AT command i sent.  I search through the datasheets and internet and didn't find anything related to this problem. Does anyone experienced this kind of issue? Thanks in Advance.
