3.2. AT Command Syntax
The syntax rules followed by Telit implementation of either Hayes AT commands, GSM
commands are very similar to those of standard basic and extended AT commands
There are two types of extended command:
- Parameter type commands. This type of commands may be “set” (to store a value or
values for later use), “read” (to determine the current value or values stored), or “tested”
(to determine ranges of values supported). Each of them has a test command (trailing =?)
to give information about the type of its subparameters; they also have a Read command
(trailing ?) to check the current values of subparameters.
- Action type commands. This type of command may be “executed” or “tested”.
• “executed“ to invoke a particular function of the equipment, which generally involves
more than the simple storage of a value for later use
• “tested” to determine:
if subparameters are associated with the action, the ranges of subparameters values that are
supported; if the command has no subparameters, issuing the correspondent Test command
(trailing =?) raises the result code “ERROR”.
Note: issuing the Read command (trailing ?) causes the command to be executed.
whether or not the equipment implements the Action Command (in this case issuing the
correspondent Test command - trailing =? - returns the OK result code), and, if
subparameters are associated with the action, the ranges of subparameters values that are
supported.
Action commands don’t store the values of any of their possible subparameters.
Moreover:
The response to the Test Command (trailing =?) may be changed in the future by Telit to
allow the description of new values/functionalities.
If all the subparameters of a parameter type command +CMD are optional, issuing
AT+CMD=<CR> causes the OK result code to be returned and the previous values of the
omitted subparameters to beretained.
