The firmware running in XBee devices contains a set of settings and commands that can be configured to change the behavior of the module or to perform any action related to it.
Depending on the protocol and firmware version, the number of settings and their meanings varies, but all XBee devices can be configured with AT commands.
All firmware settings or commands are identified with two ASCII characters.
Applications and documents refer to them as either AT settings or AT commands.
The configuration process of these AT settings varies depending on the operating mode of the device.
Configuring in AT mode
In AT operating mode, you must put the device in a special mode called command mode so it can receive AT commands.
For more information about configuring devices working in AT operating mode, see AT operating mode.
Configuring in API mode
To configure or execute AT commands when the device is in API operating mode, you must generate an AT command API frame containing the AT setting identifier and the value of that setting, and send it to the device.
You can do this with the API Frames tool.
