[Linux-zigbee-devel] 6LoWPAN and linux-zigbee (newbie)
Hello, I saw somewhere on the web that the focus of linux-zigbee moved to 6LoWPAN, beacuse of licensing issues of zigbee itself. My question is this: is currently the development of linux-zigbee intended to be integrated into the maininline linux kernel? (or already integrated)? And does the linux-zigbee project currently only implements 6LoWPAN, and not ZigBee? And last one - is there intention to implement RFC 6775 "Neighbor Discovery Optimization for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs)" in this protocol ? regards, Kevin -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.

I remember a mailinglist entry to rename this project because zigbee is a trademark. Both use the IEEE 802.15.4 layer. > My question is this: > is currently the development of linux-zigbee intended to be > integrated into the maininline linux kernel? (or already integrated)? I think at the beginning the idea was to integrate the sourceforge repo [1] to mainline. In my opinion the state of sourceforge and mainline are too different, so it's not easy to integrate anything from there into mainline. (I stopped to thinking about that) > And does the linux-zigbee project currently only implements 6LoWPAN, and not > ZigBee? Yes, there is a 6LoWPAN Implementation for IPHC and Fragmentation and some udp compression/uncompression in kernelspace. There is no zigbee implementation into linux kernel, but you can write a userspace program and get the 802154 address family packets and write some zigbee implementation. > And last one - is there intention to implement RFC 6775 > "Neighbor Discovery Optimization for IPv6 over Low-Power Wireless > Personal Area Networks (6LoWPANs)" in this protocol ? > No, for me there are too many issues in the current 6LoWPAN code. I figure out that the mac802154 layer has many others issues, too. A list of issues(Only from memory): MAC802154: - Only INTRA PAN is working - Unusual Queue handling (I count 4 Queues when you receiving a data frame to 6LoWPAN stack) - Less support of Frametypes (Only data frames are supported) - and so on... 6LoWPAN: - Unusal device handling - Wrong Fragmentation according to rfc4944 (I have a unclean fix for that) - Wrong traffic class compress/uncompression - and so on... These issues you can split into (new features) and (fixes). Currently I try to understand some more netapi to find some better solution for some 6LoWPAN/mac802154 implementation. - Alex [1] http://sourceforge.net/p/linux-zigbee/kernel/ci/master/tree/ -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
