Send and receive IPv6 data
The XBee Thread radio modules use the IPv6 network protocol instead of IPv4 to communicate between modules. These modules allow sending and receiving data in a similar manner as IPv4 devices, but it is necessary to specify an IPv6 address.
Note Only the Thread protocol supports the transmission and reception of IPv6 data. This means you cannot transmit or receive IPv6 data using a generic XBeeDevice object; you must use the protocol-specific XBee device object ThreadDevice.
