2.2.5. Command Mode
AT Commands
To Enter AT Command Mode:
To Send AT Commands:
To Exit AT Command Mode:
To modify or read module parameters, the module must first enter into Command Mode (a state
in which incoming characters are interpreted as commands). Two command types are supported:
1.
2.
Default AT Command Mode Sequence (for transitioning to Command Mode):
Send AT commands and parameters using the syntax shown below.
Figure 2‐10. Syntax for sending AT Commands
The preceding example would change the module Destination Address to “0x1F”. For modified
parameter values to persist in the module registry, changes must be saved to non-volatile
memory using WR (Write) Command. Otherwise, parameters are restored to previously saved
values after the module is powered off and then on again.
NOTE: To read the current value of a module parameter, leave the parameter field blank. For
example, the following command will return the current destination address: ATDT<CR>
System Response. When a command is sent to the module, the module will parse and execute
the command. Upon successful execution of a command, the module returns an “OK” message. If
execution of a command results in an error, the module returns an “ERROR” message.
1.
2.
For an example that illustrates programming the module using AT Commands, refer to the
Module Configuration chapter [p18].

• AT Commands
• Binary Commands
• No characters sent for one second [BT (Guard Time Before) parameter = 0x0A]
• Input three plus characters (“+++”) within one second [CC (Command Sequence Character)
• No characters sent for one second [AT (Guard Time After) parameter = 0x0A]
Send the 3-character command sequence “+++” and observe guard times before and after
the command characters. [Refer to the “Default AT Command Mode Sequence” below.] The
“Terminal” tab (or other serial communications software) of the X-CTU Software can be used
to enter the sequence.
