4.2.2. Application-layer Addressing
NI-String Addressing
Coordinator Addressing
Broadcast Addressing
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:
Broadcast transmissions are sent using a 64-bit address of 0x0000FFFF. Any RF module in the PAN
will accept a packet that contains a broadcast address. When configured to operate in Broadcast
Mode, receiving modules do not send ACKs (Acknowledgements).
To send a broadcast packet to all modules
NOTE: When programming the module, parameters are entered in hexadecimal notation (without
the “0x” prefix). Leading zeros may be omitted.
Refer to the “Broadcast Transmissions” for more information.
Application-layer addressing allows the application to specify endpoint and cluster ID values for
each transmission. Addressing multiple endpoints and cluster IDs can be accomplished by
explicitly setting these values as needed.
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.
Set the Destination Addresses of the transmitting module as shown below:
Set the Destination Addresses of the transmitting module as shown below:
