NI-String Addressing
Coordinator Addressing
API Mode provides the ability to store and maintain 16-bit network address tables on an external
processor. The 16-bit network address information is provided to the application through the
following:
With this information, a table can be built in an application that maps a 64-bit Address to the
corresponding 16-bit network address.
The ZigBee Transmit Request API frame specifies the 64-bit Address and the network address (if
known) that the packet should be sent to. By supplying both addresses, the module will forego
network address Discovery and immediately attempt to route the data packet to the remote. If the
network address of a particular remote changes, network address and route discovery will take
place to establish a new route to the correct node. Upon successful packet delivery, the TX Status
Frame will indicate the correct network address of the remote.

The NI string can alternatively be used to address a remote module.
To send a packet to an RF module using its NI-string (Transparent Mode)
To send a packet to an RF module using its NI-string (API Mode)
When the DN command is issued, a broadcast transmission is sent across the network to discover
the module that has a matching NI (Node Identifier) parameter. If a module is discovered with a
matching NI-string, the DH and DL parameters will be configured to address the destination node
and the command will return both the 64-bit Address and the 16-bit network address of the
discovered node. Data can be transmitted after the DN (Destination Node) command finishes.
the AO command. See “API Frames” section for details.
A Coordinator can be addressed using its 64-bit address or NI string as described in the “NI-String
Addressing” section. Alternatively, since the ZigBee Coordinator has a network address of “0”, it
can be addressed by its 16-bit network address.
To send a transmission to a Coordinator using its 16-bit network address:
Set the Destination Address of the transmitting module as shown below:

Issue the DN (Destination Node) command using the NI (Node Identifier)-string of the destina-
tion node as the parameter.
Issue the DN command as stated above using the AT Command API frame.
