Hi,
Befor I go deeper into CC430F6137 development can someone confirm/deny if it is compatible with
IEEE 802.15.4 standard (PHY)?
Unlike with other transceivers it is not specify (datasheet) that it does.
I see it supports ASK modulation, but does it have DSSS built in?
Is there a MAC stack for CC430?
Is there any progress on TI's 6LoWPAN?
Any pointers will be appreciated.
Regards
Jan
Hi Jan,
No, the CC430 is not compatible with the 802.15.4 standard. It uses the same radio as the CC1101 which is not a DSSS radio. It can be used for proprietary protocols with 2-FSK, 4-FSK, GFSK, MSK or OOK.
As far as I know, there are very few 802.15.4 radios available for the 900MHz band, even though the standard includes that band (TI doesn't have any). The 2.4GHz band is more globally available and has more bandwidth available. The standard for 900MHz uses a lower data rate for narrower bandwidth.
For a stack you can use SimpliciTI on the CC430, which is a simple, proprietary network protocol stack from TI.
Best,
Russ
Hi Russ,
Thank you for that explanation.
I was confused after seeing an advertisement from Sensinode about their 6LoWPAN stack running on CC430. I had an impression
that 6LoWPAN runs on top of 802.15.4 PHY and MAC. Am I right or not necessary?
As I am investigating 6LoWPAN and 802.15.4 transceivers, can I ask you what are the best 802.15.4 radio transceivers?
I know of CC2520 from TI/Chipcon and ATRF231 from Atmel (both for 2.4GHz)
Sorry but I don't know much about 6LowPAN as I have never used it.
Regarding the best 802.15.4 radios - of course TI's are the best :). I have used the CC2520 in a few projects with great success. I have looked at the Atmel radios and they look good but I have not used one in a project yet. One interesting feature I liked the looks of in the Atmel radios is the antenna diversity option. That could be a great feature for some applications.
Good luck,
All,
TI is getting ready to release a 6LoWPAN development kit based on the CC1180 and CC430 series Sub-1GHz devices. We are in the process of finalizing the documentation and release it. You will be able to find more information about the kits at:
http://processors.wiki.ti.com/index.php/CC-6LoWPAN
You will find when reading the Wiki that 6LoWPAN is not fixed to any specific PHY. 6LoWPAN is just a standards based method for reducing the networking overhead of IPv6 for use in memory/speed constrained system. It is possible to run 6LoWPAN on 802.15.4 or 802.15.4g or even PLC.

Hello,
Where is information on the CC1180?

Derek,
Please contact your local FAE or TI Sales reps for more information about the CC1180.

Hi TA,
Thanks for that info and link.
Can you be more specific about the time-frame, is it a matter of months or weeks?
Does the stack come with source code or binary only?
Jan,
Thanks for your interest. We are in early adopter sampling phase now and it will be generally available in late Q1. There are two options:
For both cases we have prepared examples for you get started with.
In addition to TA's comments; the TI/Sensinode development kit will be using a early-version of 802.15.4g frame format. I.e we'll implement as much support for 802.15.4g as possible on the CC1180/CC430 HW.

TA, Jonas,
Good to hear that TI is taking seriously that part of Low Power RF (6LoWPAN) and thanks for all the information provided.
I contacted my local TI people (both Sydney and Melbourne) as advised by TA to ask for more info on CC1180, however they are struggling to find any.
Would it be possible to pass the above mentioned documentation to them Down Under so they can pass it to me and others?
Again, appreciate your support.
Since CC1180 is not yet a released part it not possible to share the datasheet yet. As TA mentioned above you can find more information on the developer wiki: http://processors.wiki.ti.com/index.php/CC-6LoWPAN
Is there any progress on it?
"TI is soon to release a development kit based on TI hardware and Sensinode software for the 868/915 MHz band, utilizing CC430 or the network processor CC1180"
I am looking here http://processors.wiki.ti.com/index.php/CC-6LoWPAN#What.27s_included_in_the_kit.3F
There are 2 diagrams under 6LoWPAN and IPv6 Basics section, specifically:
6LoWPAN CC1180 WNP Stack and 6LoWPAN CC430 Stack
There is a box saying IEEE 802.15.4 Radio within CC1180 and same within CC430Fx (and it was said before, they are not 802.15.4 radios)
How to interpret it?
I'd also like to know if there is any time frame that can be shared at this point.
Also, is it possible, as part of the early adoption stage, to get a 6LoWPAN unit or two to play with?
Thank you,
Cristian
Targeted release for CC-6LOWPAN-DK-868 is 2H11.
Contact your local TI sales representative for information on the Early Adopters program.
Cheers,
Jonas
