Hi, all, >I don't know if there was any licensing issues. Programmers don't have time to read non code... This is what the wiki says: http://sourceforge.net/apps/trac/linux-zigbee/ . . . "While this project was originally started to create a ZigBee implementation for Linux, licensing restrictions put in place by the ZigBee Alliance make it impossible for an implementation of ZigBee to ever become part of the Linux kernel. Once this licensing issue was discovered, this project's primary focus shifted to IEEE 802.15.4 and 6LoWPAN. " . . .
Could it be related somehow to ZigBee lincense ? (http://www.zigbee.org/) Moreover, I saw in a lecture: http://elinux.org/images/7/71/Wireless_Networking_with_IEEE_802.15.4_and_6LoWPAN.pdf from 2012, by Alan Ott: "Wireless Networking with IEEE 802.15.4 and 6LoWPAN" slide 6: A Word About ZigBee ● ZigBee's license conflicts with the GPL and other Free Software licenses. ● Until the ZigBee Alliance changes their license, there will likely not ever be an implementation of ZigBee in the Linux kernel. Any ideas ? is this relevant ? regards, Kevin On Thu, Sep 19, 2013 at 9:47 PM, Alexander Aring <alex.ar...@gmail.com> wrote: > Hi Kevin, > > On Thu, Sep 19, 2013 at 07:21:09PM +0300, Kevin Wilson wrote: >> Hello, >> I saw somewhere on the web that the focus of linux-zigbee >> moved to 6LoWPAN, beacuse of licensing issues of zigbee itself. >> > I don't know if there was any licensing issues.
