2.5.4. Command Mode
To modify or read RF Module parameters, the module must first enter into Command Mode - a
state in which incoming characters are interpreted as commands. Two Command Mode options are
supported: AT Command Mode [refer to section below] and API Command Mode [p54].
AT Command Mode
To Enter AT Command Mode:
Default AT Command Mode Sequence (for transition to Command Mode):
" No characters sent for one second [GT (Guard Times) parameter = 0x3E8]
" Input three plus characters ( +++ ) within one second [CC (Command Sequence Character)
parameter = 0x2B.]
" No characters sent for one second [GT (Guard Times) parameter = 0x3E8]
All of the parameter values in the sequence can be modified to reflect user preferences.
NOTE: Failure to enter AT Command Mode is most commonly due to baud rate mismatch. Ensure the
Baud setting on the PC Settings tab matches the interface data rate of the RF module. By default,
the BD parameter = 3 (9600 bps).
To Send AT Commands:
Figure?08.燬yntax爁or爏ending燗T燙ommands?/DIV>
To read a parameter value stored in the RF modules register, omit the parameter field.
The preceding example would change the RF module Destination Address (Low) to 0x1F . To store
the new value to non-volatile (long term) memory, subsequently send the WR (Write) command.
For modified parameter values to persist in the modules registry after a reset, changes must be
saved to non-volatile memory using the WR (Write) Command. Otherwise, parameters are
restored to previously saved values after the module is reset.
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:
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 [p25].
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.]
Send AT commands and parameters using the syntax shown below.
1. Send the ATCN (Exit Command Mode) command (followed by a carriage return).
[OR]
2. If no valid AT Commands are received within the time specified by CT (Command Mode
Timeout) Command, the RF module automatically returns to Idle Mode.
