2 Introduction

This highly integrated wireless communication module, embeds all of the necessary
components to perform a virtual plug and play function for ZIGBBE RF transceivers.
The module contains many of the necessary features required to built a reliable RF
communication network such as;, anti-interference ability, support for multiple network
topologies including self healing features, point to point, or point to multipoint
configuration which can be composed as star, tree, mesh tree network structure and of
course low power modes. .

The module is divided into a center coordinator, routers and end nodes, these three
distinct modes of operation provide the user with the option for different network
Structures that can be optimized for the particular application. The center of the network
is the coordinator node which is responsible for launching the network’s organization,
network maintenance and management, The data router function built-into the device,
which is responsible for transferring the data within the Zigbee network to the
coordinator and eventually to the host. The terminal nodes are typically at the end of the
network and typically perform the sensing and data acquisition function.

The coordinator, routers and end nodes configured by software commands. .

4 Product performance

4.1.1 Low power consumption

This module can be configured in a variety of energy-saving modes, in which it is possible to

have a fully operational system run for more than 6 months on two AA batteries.

4.1.2 Network self-organization, self-healing ability

The Network configuration features of this module will allow the self-organizing of the network
without human intervention. The network’s nodes can sense the presence of other nodes and
determine the connection between composition and structure of the network;

The self-healing function can change the order in which data traverses through the network to
compensate for a change in node position, or node failures, etc. Low cost

This Zigbee module operates in the unlicensed ISM band at 2.40 GHz~2.48GHz and comes with
royalty-free firmware thereby yielding an extremely low cost system solution.

4.1.3 Network capacity

The specification for Zigbee network does allow for up to a maximum of 65,534 nodes in the
particular network. The Zigbee module can be configured to communicate via a standard serial

data (RS232 data) via the UART interface, and the firmware will allow you to transmit broadcast
messages to the other devices in the network. Any module in the network can be queried from the
coordinator to determine it operational mode and its relative position within the network.

7.1 Mode switch port

Input/ output port PIO_01 is configured as a mode switching port. When the module is controlled by an

external microprocessor switching this pin will allow the user to switch between the normal operation

running mode and the command mode. When the mode pin is set to a logic low level “0” the module is in

the active, operational mode. When the mode pin is set to logic high state “1” then the module is in

configuration parameters. See table below for a summary.

Mode pin State Operational state
Logic low Zigbee network operational MODE
Logic high Command mode

7.4 Configuration Interface

When the ZIGBEE wireless communication module MODE switch pin (PIO_01) pin is

connected high, the system enters the command mode; low on this pin will shift the module’s

8 The UART

The module provides four-wire+ Ground serial asynchronous communication interface;
The following diagram shows the TXD, RXD, CTS, RTS signals for the UART and the direction of the
data flow. The voltage levels of the UART are low= 0 Volts and Hi = Vdd (3.3Volts). For two (2) wire +
Ground operation do not connect CTS and RTS.

receive the broadcast message.

coordinator. The other nodes in the network simply act as a pass through and do not actually receive the
serial data. The Serial Data terminates at the Central coordinator.

2) Point to point Mode: When operating in point to point mode: the node must format the data as outlined

below, such that the serial transmit and receive data are properly interpreted. (See below for the specific
point to point data format )

10 Point-to-point mode Data specification

When the module is operating in point-to-point mode the data format is based on following format. If the
module are not configured to receive the serial data in to following format then data will be considered
invalid. The AT+_SENDTYPE =2 is the appropriate command.

10.1 Overview of the data packet format (point -to-point)

Packet format is defined as the 5 byte header plus valid data, as follows:

Sync Package Type Sequence Number Data length Valid data

0x55 0xAA 1 Byte 1 Byte 1 Byte

1) Sync: each packet by 0x55, 0xAA start a data packet used to synchronize

2) Package Type: 1 byte length type field, used to indicate the type of the current packet, the case of AT

commands or other types of packets.

Specific packet types are as follows:

Package Type Help Data transmission direction

0x 00

0x01

Additional AT Command Request External MCU Æ Zigbee Module

0x20

3) Sequence Number: This parameter is one byte in length and it represents the sequence of commands

form a particular module. The Serial number sequence is first set by the Zigbee module during the
0x20 package receiving response. Each subsequent communication the serial number will be
incremented by one (1)

4) Data length: 1 byte of data length field, which contains the number of bytes of data. Maximum data

length is

5) Valid data: This field is data, and the length of the data is indicated by the previous byte. .

80 bytes.

10.2 Additional AT command request (0x00) & Response (0x01) Packet

In point to point mode, the following example is used to show how to inquire the local MAC address. This

method can also be used to, a) MAC address lookup of remote devices through a short address queries
through the network Remote

The zigbee module will send the following data

55 AA 10 0C 00 01 48 65 6C 6C 6F 57 6F 72 6C 64.

Special Note:

When the transmission of data starts, the load flow of data packets can be very large, it is recommended to enable

the module's flow control model, which ensures reliable high-speed data transmission.

• If hardware flow-control is set to enable then the external microprocessor must strictly follow flow

control configuration for the entire packet (0x01) including the effective length up to
handle). And the transmission response message (0x20) must be confirmed.

• If you choose not to use flow control then the transmit packet and the reply packet (0x20) for a way to be

should have less than a 100ms delay, otherwise it is possible that there will be a loss of data.

11 Mounting Recommendations

11.1 Recommended Module Locations for On-Board Antenna

For maximized performance please orient the device with the antenna as close to the outside of the
housing as possible. Best performance will occur if the underlying PCB does not have a ground plane
under the area where the antenna is located. A ground plane directly underneath the antenna region will
drastically reduce the range of the module. The absolute minimum nearest ground plane should be 3mm
away from any point on the antenna; 5 mm or greater is preferred.

Solder Profile

ZBA Inc.

NOTE: Contact ZBA if you wish to reflow the Modules in your production environment. There are

specific configurations that need to be reviewed with the production facility to allow for proper reflow of

the modules. SAMPLE QUANTITIES OR SMALL PRODUCTION RUNS WILL TYPICALLY BE

CONFIGURED FOR HAND SOLDERING

The soldering profile depends on various parameters necessitating a set up for each application. The data
here is given only for guidance on solder re-flow. There are four zones:

1. Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-2.5°C/s.

2. Equilibrium Zone - This zone brings the board to a uniform temperature and also activates the

flux.

3. The duration in this zone (typically 2 -3 minutes) will need to be adjusted to optimize the out

gassing of the flux.

4. Reflow Zone - The peak temperature should be high enough to achieve good wetting but not so

high as to cause component discoloration or damage. Excessive soldering time can lead to inter­metallic growth which can result in a brittle joint.

5. Cooling Zone - The cooling rate should be fast, to keep the solder grains small which will give a

longer lasting joint. Typical rates will be 2-5°C/s.
