Chapter ? 2 ?‐? RF ? Module ? Operation
2.2.6. Command Mode
To modify or read module parameters, the module must first enter into Command Mode (state in
which incoming characters are interpreted as commands). Two command types are supported:
? AT Commands
? Binary Commands
For modified parameter values to persist in the module registry, changes must be saved to non-
volatile memory using the WR (Write) command. Otherwise, parameters are restored to previously
saved values when the module is powered off and then on again.
AT Command Mode
To Enter AT Command Mode:
1.
2.
Send the 3-character command sequence "+++" and observe guard times before and after
the command characters. [refer to ‘Default AT Command Mode Sequence’ below.] The ‘Ter-
minal’ tab (or other serial communications software) of the X-CTU Software can be used to
enter the sequence.
[OR]
Assert (low) the CONFIG pin and turn the power going to the module off and back on (or
pulse the SHDN pin).
[If the module is mounted to a MaxStream RS-232/485 Interface Board, the result can be
achieved by pressing the configuration switch down for 2 seconds.]
Default AT Command Mode Sequence (for transition to Command Mode):
? No characters sent for one second [refer to the BT (Guard Time Before) Command]
? Input three plus characters (“+++”) within one second
[refer to the CC (Command Sequence Character) Command.]
? No characters sent for one second [refer to the AT (Guard Time After) Command.]
All of the parameter values in the sequence can be modified to reflect user preferences.
To Send AT Commands:
Send AT commands and parameters using the syntax shown below.
Figure ? 2 ‐ 09. ? Syntax ? for ? sending ? AT ? Commands ?
To read a parameter value stored in the module register, leave the parameter field blank.
The preceding example would change the module’s Destination Address to "0x1F". To store the
new value to non-volatile (long term) memory, the Write (ATWR) command must subsequently be
sent before powering off the module.
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.
To Exit AT Command Mode:
1.
2.
If no valid AT Commands are received within the time specified by CT (Command Mode
Timeout) Command, the module automatically returns to Idle Mode.
[OR]
Send ATCN (Exit Command Mode) Command.
For an example of programming the RF module using AT Commands and descriptions of each config-
urable parameter, refer to the "RF Module Configuration" chapter [p19].
