Send AT commands
Once the device enters Command mode, use the syntax in the following figure to send AT commands. Every AT command starts with the letters AT, which stands for "attention." The AT is followed by two characters that indicate which command is being issued, then by some optional configuration values.
To read a parameter value stored in the device’s register, omit the parameter field.
The preceding example changes NI (Node Identifier) to My XBee.
Multiple AT commands
You can send multiple AT commands at a time when they are separated by a comma in Command mode; for example, ATNIMy XBee,AC<cr>.
The preceding example changes the NI (Node Identifier) to My XBee and makes the setting active through AC (Apply Changes).
Parameter format
Refer to the list of AT commands for the format of individual AT command parameters. Valid formats for hexidecimal values include with or without a leading 0x for example FFFF or 0xFFFF.
