Errors and Messages

The command result codes "+CME ERROR:

<err>

" and "+CMS ERROR:

<err>

" indicate errors related to mobile

equipment or network functionality.

The format of

<err>

can be either numeric or verbose and is selectable via

AT+CMEE

A result error code terminates the execution of the command and prevents the execution of all remaining com-

mands that may follow on the same command line. If so, neither "ERROR" nor "OK" result codes are returned

for these commands. A 30 seconds timeout will deliver "ERROR" when the input of a command is not complete.

Using the wrong command syntax may result in errors: For example, using the execute command syntax

although the command has no execute format, causes "ERROR" to be returned. Likewise, using the write com-

mand syntax although the command has no write format causes "+CME ERROR:

<err>

" to be returned.
