Does anyone else see this? Yes me, currently only Dataframes are supported and when you get an another frametype then it will show this message.
So your frametype is 0 and this is a beacon frame. We don't handle beacon frames at the moment. But you don't get any (type = 2)? > > I then tried a ping6 and this was ok.

It doesn't show the mac header... but this isn't unusual. It's because the current architecture with a wpan and a lowpan device. I need to think about this if we can handle this anyway. > We've still got a few issues to sort on our receiver so as soon as > this is fixed I'll let you know how I get on with the fragmentation. > if you using ssh you should already used some fragmentation. Try a ping6 -s $SOME_SIZE_MORE_THAN_127 (my contiki usb stick can handle up to 1024 bytes and a smaller sensornode can handle 135 bytes. It's possible to use a (2^16)-(PING_ICMPv6_HEADER) size but this will end in a high fragmentation. In a linux<->linux connection without ACKs I can use ~8KB without trouble and this sounds good. In a normal sensornetwork you don't want a 8KB payload) - Alex ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
