The ZAURA RF Wireless Library
This ZAURA RF Wireless Library Programmer’s Reference Manual
describes the architecture and application programming interface that
allows software developers to integrate ZAURA RF Wireless modules
into their products.
Zilog’s ZAURA RF Wireless Modules can be designed into any system to
enable wireless control. The ZAURA RF Wireless Library is used to
establish an ad-hoc peer-to-peer network over radio frequencies in the
Industrial, Scientific and Medical (ISM) band with raw data rates of
50 Kbits/sec. Nodes with compatible configurations within radio range of
each other can communicate directly using either point-to-point or point-
to-multipoint data transfers. The ZAURA RF Library allows developers
to configure, transmit and receive packets on the networks.
ZAURA RF Wireless Module Topology
The ZAURA RF Wireless Module uses an ad-hoc topology. Nodes with
compatible configurations within radio range of each other communicate
directly using either point-to-point (unicast) or point-to-multipoint
(broadcast) data transfer. There is no central coordinating unit in the
ZAURA RF Wireless Network through which nodes must communicate.
This network does not provide routing of any kind between nodes that are
not within radio range of each other. There is no concept of master or
slave in the ZAURA RF Wireless Network; all nodes operate as equal
peers. The modules’ configuration parameters determine whether nodes
will be able communicate with one another when they are within range.
The ZAURA RF Wireless Network configuration parameters consist of
the RF Channel, Network ID and Frame Format. There are two versions
of the ZAURA RF Wireless Module, one using the 868 MHz Frequency
band and the other using the 915 MHz frequency band. The ZAURA RF
channel determines which subset of frequencies within the band are used
