User Guide Troubleshooting the FX Series
Enable the verbose error report method to see the error codes associated with the command syntax.

Enter the AT+CMEE=1 command in order to change the error report method to the verbose
method, which includes the error codes.

Re-enter the AT command which previously caused the reception of an
“ERROR” message in
order to get the Mobile Equipment error code.
When the verbose error report method is enabled, the response of the FX Series in case of error is
either:

+CME ERROR: <error result code>
or

+CMS ERROR: <error result code>
Refer to documents [1] Open AT Application Framework AT Commands Interface Guide and [2]
AirPrime SL808xT and Q2698 Open AT Framework Commands Interface Guide for more information
on the error result code description and further details on the
AT+CMEE command.

Equipment error code (enter the
AT +CMEE=1 command).
