1.9 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.
