•
AT command syntax is incorrect: check the command syntax (refer to "AT Commands Interface
•
AT command syntax is correct, but transmitted with wrong parameters:
•
Enter
the
AT+CMEE=1
command in order to change the error report method to the verbose
method, which includes the error codes.
•
Enter again the AT command which previously caused the reception of "ERROR" message in
order to get the Mobile Equipment error code.
When the verbose error report method is enabled, the response of the FASTRACK Supreme in case of error
is as follows:
•
CME ERROR: <error result code>,
•
Or +CMS ERROR: <error result code>.
Refer to "AT Commands Interface Guide" [6] for error result code description and further details on the
AT
+CMEE
command.
Note
: It is strongly recommended to always enable the verbose error report method to get the Mobile
Equipment error code (enter
AT +CMEE=1
command).
