All,

Atmel has just launched the AT86RF212 radio transceiver. It builds on the legacy of the AT86RF230 used in the RZRAVEN kit and AT86RF231.

This is a 868/915MHz part.

Find more information here: http://www.atmel.com/dyn/products/product_card.asp?part_id=4349

Yo, Atmel - if you're reading this, how about handing out a few of these? Little users like samples, too.

I would like to evaluate this one. It certainly looks useful.

There's more than an evening's reading in the datasheet!

seems one of the few 802.15.4 with the 868/915MHz band.
can we expect some other versions of raven with the new chip? :D

change without any change is no change ;-)

Interesting. The fact that 2.4GHz band has high absobtion by water, makes us drop the ZigBee idea. With this new IC, then probably we would reevaluate again.

Will this be easier to use than the Raven?

Can it be used for the same sort of things?

That's something like apples and, no, not oranges but monkeys.
Or like asking whether the ATmega169 is easier to use than the
AVR butterfly... one is an IC, the other one is a demonstration/
evaluation board.

This chip WILL make mid-band UHF (2.4GHz being high UHF) much more common. 802.15.4 is designed for both mid-band and high-band BUT NOT 430MHz (low-band UHF). There are already a few ZigBee devices working in this band, but, now, there will be a LOT more. It also means adding this frequency range to XBee and other 802.15.4 derivatives, as well as 6LOWpan.

I am REALLY encouraged!

Yes, it will be good to have a choice in the bands. Hopefully, it will just ba a case of dropping the right transceiver module onto a board.

i found some interesting news about the chip and its support from meshnatics
http://www.eeproductcenter.com/r...

hope its useful :D

Has anybody been able to get their hands on any Si yet? I just pinged my local Atmel rep to see if they can hook us up. This part looks great! The link budget on it is massive, and with built in support for an external PA as well as support for antenna diversity - this looks like a winner to me. I'm still sifting through the documentation (173 pages! Good lord!) but so far so good!

It does look interesting, especially since I'm working on a project where I intend to use some wireless nodes.

Does anyone know whether there is a c library for driving this transceiver? Or is it similar to that for AT86RF23x?

It's fairly similar to the AT86RF231. Obviously though, there are major
differences when it comes to frequency and modulation selection (aka.
channel and channel pages, in terms of IEEE 802.15.4-2006).

Is there a board (hopefully inexpensive) with AT86RF212 and PCB antenna?
Is there a reference design with PCB antenna and matching balun in public domain?

ZigBee has nothing at all to do with the frequency band or modulation methods. ZigBee is the name of the network layer protocol. ZigBee is to IEEE 802.15.4 as IP is to 802.3 or IP is to 802.11.

So 802.15.4 defines 2.4GHz along with 868/900MHz as options. The 2.4GHz option is by far the most popular because the other bands are not available internationally and universally.

Lastly, the comment that 2.4GHz is vulnerable (to high propagation losses) due to water (rain, fog) is, in my training and experience incorrect. There are much higher frequency bands that do have attenuation issues at high rain rates.

The propagation of 802.15.4's 2.4GHz 2MHz channel DSSS with Offset QPSK is superb. It works down to 4dB SNR. I've done lots of field tests and work and it never ceases to amaze me how well it works, even with 1 or 10mW, in terms of path length and RF occlusions in the path.

But note that 802.15.4 defines the modulation method so in truth, there is a negligible difference in link budget among the many MAC/PHY interoperable '15.4 chips and certified module products. The differentiators are of course the EIRP that you can legally use in your country and that's quite low in most of Asia and France and other places, unlike No. America.

We tested some modules from Freescale (with some troubles with Freescale's local representative) in our application, and it seemed to us that it could give us some issues for the intended application (it involves high humidity, lots of water and ice, frozen food, and some metal walls).

Anyway, this problems could be also due the firmware running in the Freescale modules, so it could be interesting to try again with RAVEN kits (with a better link budget), and even better, at this low frequency.

ZigBee 'per se' (I mean by the protocol itself, not due link issues) was really interesting, and was not totally out of scope, since we need the mesh facility. 6lowPAN adds certain advantages though (royalties, code, etc). But this was not the main reason behind the decission to drop this idea.

Since this is intended to be CE for all Europe, then we should take a look at local limtations.

Steve, does weather radar, that wants to see a cloud full of water, operate about 2.45GHz? And does search radar that wants to punch thru them, operate at 8-10GHz, or is my old rememberer starting to drop bits?

I just got a pair of eval boards from dresden elektronik, but im clueless how to start programming them. Does anyone know of a good starting tutorial for the at86rf212??? anything will be of great help

The software for an IEEE 802.15.4 MAC is coming with the AVR 2025 application note.
If you want to start directly at transceiver level, have a look at http://uracoli.nongnu.org/manual... . I would recommend an anonymous check out of the sources directly from the µracoli CVS.

Hi,

I had bought the RZ600 kit, and i had doubt about MAC address.

Every transceiver stick has unique ID which is written on board but where it is stored in transceiver module.

I had gone through Data sheet of At86RF212B but no where i had found about this MAC address.

Thanks in advance

Regards
