Yes, I also see the simpleRPL and some other implemeation, but it's strange that there is no general one. Thanks for your explanation. I also see the inter-operation issue between contiki and linux solution.....maybe that's another challenge. -----Original Message----- From: Alexander Aring [mailto:alex.aring@xxxxxxxxx] Sent: Wednesday, October 22, 2014 5:02 PM To: Zhang, Baoli Cc: linux-zigbee-devel@xxxxxxxxxxxxxxxxxxxxx; linux-wpan@xxxxxxxxxxxxxxx Subject: Re: [Linux-zigbee-devel] Questions about the Zigbee in Linux On Wed, Oct 22, 2014 at 08:27:34AM +0000, Zhang, Baoli wrote: > Hi, > > Great, thanks Alexander. > > I also don't see the RPL implementation.....not integrated?

For me it is important to get a working 802.15.4/6LoWPAN implementation at first. But currently there exist no general RPL implementation, some people tried to implement a userspace solution. It would be really nice to have it, but we also detect some critical 6LoWPAN bugs which indicates that multicast, etc... was always broken before. :) - Alex ��.n��������+%������w��{.n�����{�� Z���ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
