64-bit address

Every XBee device has a 64-bit address to distinguish it from others and prevent duplicate information. That address (also called MAC) is assigned to Digi by the IEEE and is guaranteed to be unique, so two devices cannot have the same address.

You can determine the value of the 64-bit address by reading the Serial Number High (SH) and Serial Number Low (SL) parameters on any device. It is also printed on the back of the device.

Note The concatenation of SH + SL forms the 64-bit or MAC address of the device. It is stored in the device's memory as two 32-bit values: the high part, SH, and the low part, SL. The high part is usually the same for all XBee devices (0013A200), as this is the prefix that identifies Digi devices. The low part is different for every device.

The 64-bit address of 000000000000FFFF is reserved for sending a broadcast message.
