Hi,

I want to design Zigbee node based on Atmel Atmega128 and AT86RF230/231.

That's why I have initiated this forum.
As far as I know Atmel provide zigbee meshnetic stack by means of Meshnetics.Is it true?

AT86RF230 and AT86RF231 two chip, are they compatible? May I replace one by another?

Have you checked the RZRaven section on Atmel's web-site?

Have you compared the respective data-sheets? What do they say about compatibility?

you mean to say that Zigbee Processor which has inbuilt Zigbee stack.
It is very good I can use it just like module.
But it is very costly(8$)

With compare to 8$ atmel. (Atmega128+Atrf230)

Be sure that you undestand the difference between
ZigBee
IEEE 802.15.4

as you do for
TCP/IP
IEEE 802.3

Basically yes, but the AT86RF231 is newer, and offers some more
options (like the builtin AES module, or the antenna diversity
algorithm). Note that they are not binary compatible,
i.e. some register bits are at different locations even though
they've got the same name.

What may be practical range achieved by AT86RF230 transceiver without any amplifier?
Has any one worked on this transceiver?
Do I necessarily require development kit for this?
Or I will be able to work without it?

That heavily depends on your environment, and your antenna(s).
Using the 6 dBi (nominal value) gain antenna of the RZ200 device,
in free space communication is possible up to a distance of 1 km.
However, the steel-armed concrete wall next to you might as well
cause a full stop for the 2.4 GHz waves.

For typical office or home situations, you can probably expect
ranges of several 10 m, up to maybe about 100 m. Obviously, this
requires the frequency spectrum to be sufficiently free from other
interferers, like microwave ovens or WiFi networks.

I just released the v0.5 version of the FreakZ Zigbee stack on Sourceforge. You can download the source code here:
http://sourceforge.net/projects/...

Its still an early version and only works in the simulator, however the next step is to port it into actual hardware.

Actually, thanks to an applications guy in Dresden, I got a bunch of Atmel AT86RF231 boards so it looks like the first hardware platform it will be ported to is the Atmel radio. Thanks Ingolf.

Anyways, its gonna still be a while, but there will be an open source Zigbee stack that can work on Atmel and other MCU/radio combinations soon. Hopefully next year, the stack will be stable for a 1.0 release and compliance testing.

re open source
As I recall, the work of UCLA and/or UC Berkeley on a mesh routing implementation is open. Perhaps a derivative of it is used by Crossbow and perhaps early versions of modules such as jennic and meshnetics.

Being licensed/controlled by the ZigBee alliance, an open source version of that may be contested legally.

What is more interesting than ZigBee as a network layer for 802.15.4 is 6LoWPAN which is based on an IETF RFC and is truly open. A huge void in ZigBee PRO is the lack of a standard for time synchronized MAC layer rendevous so that one can have battery powered mesh routing nodes. 6LoWPAN is near to having that.

Another fairly open near final standard that DOES have support for battery powered mesh routers is ISA 100.11a. Dust, Inc. is a contributor to the standard in this area. But like ZigBee, ISA controls the trademark and intellectual property use.

Battery powered mesh routers are a requirement in many applications where mesh node members are nomadic or portable. Such as asset tracking in logistics where sensor status important and less so asset location.

ZigBee defines end-nodes as non-routers and has provisions for them to sleep for power consumption. Not so "full function devices" in the mesh or cluster-tree topologies.

The ZigBee gang missed the market window for home automation, such as it is (Z-Wave), and is now chasing the automated utility meter reading (AMR) and automated remote control of power-consuming devices (the wonderful future of time-of-day based rates for electricity for one). This is called the AMR/AMI market. ZigBee has some traction with large utilities, but many meter manufacturers oppose a totally open standard for competitive reasons. In AMR/AMI, the mesh nodes are rarely battery powered.

Atmel mention that they provide free stack by means of Meshnetics ezeenet stack.

So can this Ezeenet stack be used for demonstration of complete zigbee based working hardware system?

Meshnetics also provide BitCloud Stack which may be licensed version.But I can afford that stack right now.
So is it possible to work on Ezeenet stack for hardware development and then to migrate for Bit cloud stack?

I only have STK500 kit with me?And may be AVR JTAGMKIICE programmer.

Will I be able to develop complete zigbee node based on this by using ezeenet stack?

Or I should not waste my time by doing this?

Hi,

I want to prepare PCB of Gerber file provided by ATMEL for RZ502 RF board.

Is it fine to use FR-4/1.6mm board for its PCB?

Or I will have to use some specific board for this purpose.

Please guide me for this if you have any idea.

Hi,
I am implementing RZ500 board(zigbee RF node).

I got its PCB gerber file from the Atmel website named AVR414.

But problem with me is it do not include Drill file and tool list file.

Do you have any details about where to get this complete PCB gerber file.
