6.2 Receiving "ERROR" Message

The M1306B returns an "ERROR" message (in reply to an AT command) in the

following cases:

• AT command syntax is incorrect: check the command syntax (refer to "AT

Commands Interface Guide" [7]),

• 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 M1306B in

case of error is as follows:

• Either +CME ERROR: <error result code>,

• Or +CMS ERROR: <error result code>.

Refer to "AT Commands Interface Guide" [7] for error result code description and

further details on the

AT +CMEE command.

Note

: It is strongly recommended to allways enable the verbose error report method

to get the Mobile Equipment error code (enter

AT +CMEE=1 command).

6.3 Receiving "NO CARRIER" Message
