The XBee Series 2 endpoint table operates similar to the binding table. Entries may be added,
removed, or viewed using the E+, E-, and EV commands respectively. Some table entries are
reserved for special purposes
Table 4‐04.
The command endpoint is used to send or reply to various commands. This endpoint must exist in
the application.
This endpoint is used to send serial data to other XBee Series 2 modules. It must always exist in
the application.
This entry is used as needed to define the source endpoint that must be defined for a data
transmission. If a transmit request is made, and the specified source endpoint does not exist, it
will be created temporarily at this endpoint table index.
User endpoints are controlled entirely by the application. These endpoints may be added,
removed, or viewed in the API firmware using the following commandsSee the command
descriptions for command formatting details. At present, changes to the endpoint table are saved
to non-volatile memory when WR is issued..
Table 4‐05. ZigBee Data Transmissions Addressing Fields
Network mapping has provisions to identify all devices on a PAN.There are currently two ways to
do this either through the Node Discover (ND) Command or the API Child Joined Indicator. Both
are explained below.
Issuing the ND command on a device sends a broadcast node discovery command throughout the
PAN. All devices that receive the command will send a response that includes the device’s 64-bit
and 16-bit addresses, along with the NI-string and other information.
Routers and end devices can be configured to send a transmission after joining to alert the
coordinator, or the entire network, that the device has joined the network. When this message is
transmitted, the receiving device(s), if running API firmware, will send an advanced modem status
indicator out the UART to indicate the 64-bit and 16-bit addresses of the joining device.
