Three roads to introduce ZigBee in your product

1. Develop your own application software

2. Hire a consultant-company which has the rights to develop on a software stack-platform

3. Buy an all-embedded module (SPPIO)

Radiocrafts

Member of:

Developing your own application software

- Buy the PHY (radio) + Microcontroller (MCU) + MAC (software and/or hardware)

= RC2200/AT/MM- Buy the rights to use a stack (IP=$$$) and the stack

object code which works on the MCU- With the required tools, develop your application on

top of the stack/MAC/PHY and download on the MCU

Setting up an SPPIO network IAll configurations are done by AT-commands at

the UART interface! The basic steps are:1. Configure one module as the PAN

Coordinator2. Configure all other modules as Routers or End

Devices3. Bind or pair devices by mapping one’s unique

address as the other’s destination address4. Select the UART data transmission scheme

(on full buffer, end character or timeout)

Radiocrafts

Member of:

Setting up a SPPIO network II5. Configure the I/O pins to either analogue or

digital6. Configure the I/O port direction (input or

output)7. Select the I/O data transmission scheme (on

events, interrupts or timers)

The Routers and End Devices will automatically associate to the network coordinator as soon as they are switched on. And all the devices will organize themselves in a mesh network with automatic routing. UART data and I/O data will then be exchanged or mapped between devices that are paired.

-Entering Command Mode; +++, AT$, AT0

-Power saving modes;

Power Down: ATPD-command; (1.3uA)

Needs to re-associate when turn on again

Sleep: SLEEP_MODE parameter to 0 (<20uA) Wakes up on UART interrupt or I/O interrupt (End Device only)

Setting when to do the I/O mapping between paired modules:0: on UART activity1: on pin change2: on interval

Interval-transmissions of the I/O data (default. 1 second) Enable 1 second interval on the transmitter:

ATS10=2ATS11=25

Enable UART-appending on the Receiver:ATS27=1

Will give UART data string;

ZigBee vs. proprietary radio solutionsZigBee is NOT the answer to all wireless communication

needs due to:- Range: 120-170 meter Line-Of-Sight, indoor 10-30

meter indoors, neighbouring room (0 dBm)- Interoperability: Today only one public profile is defined

(HCL)- Extensive development cost and effort with specific

customer application layer - Not for data streaming (audio/video) but smaller data

packets at periodic intervals- Star network (point-to-point) sufficient in most

applications- ZigBee Routers is > 64k program memory ($$$)

Why use Radio Modules?- One single component instead of 20-60;

Less logistics, rapid prototyping, proof of concept- RF knowledge limited to adding an antenna. Shielded modules,

less interference. Easy mounting on cheapest carrier PCB.- Pre-qualified: CE-marking can be re-used (Declaration of

Conformity)- All modules are 100% RF-tested, final product can be function-

tested only (no RF production test-equipment), no yield loss in production

- Simple-to-use standard UART interface: Easy connection to RS232/485 or MCU

- RF-development time reduced from 3-6+ months to weeks- Total development- and production cost significantly reduced- Time-To-Market shortened
