Hi, now I will comment some things about the mail here in linux-wpan.

This was the first important thing which was needed to change after now maintainership. To send everything into bluebooth-next this is just because Marcel (bluebooth maintainer) was very friendly and offered to apply everything which is for linux-wpan into bluebooth-next. This behaviour should be changed if the stack implementation is in a more useable state. Since there exist a BTLE 6LoWPAN draft, the BTLE 6LoWPAN and 802.15.4 6LoWPAN implementation shared the IPHC format. > As last resort on ETX and MRHOF on linux and to see it working, I just > tried to use nd6 timers as indication on link quality on linux side. > Basically, when some neighbour moved to state REACHABLE would count as a > good packet delivered.

Since there exists also BTLE 6LoWPAN a RPL implementation is good to have for both subsystems (bt/802.15.4). > About the blog which talks about tests to RPL Linux implementation, I just > want to say that I wasn't contact about it before the post. > I would say, you need to do your things mainline. Maybe simple write a mail to netdev@xxxxxxxxxxxxxxx and talk about your plans for implement your stuff, I think you will 100% get some response to that. Then send patches to netdev so we have your RPL implementation mainline. To get stuff mainline is the most important thing. If you need help to getting patches stuff mainline, I can offer you my help if you want. - Alex [0] https://docs.zigbee.org/zigbee-docs/dcn/05-3739.pdf -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
