Run wireshark on your Linux box and capture from the network interface. First packet received will crash the kernel.

This needs to get sorted out to something that works. - As discussed in previous posts in linux-zigbee mailing list, > I had to have my channel setted (done as a hack of mac802154_wpan_xmit() > from net/mac802.15.4/wpan.c) to see my packets sended. there's no good UI for changing the channel at the moment.

There is some stuff that needs to be sorted out in Contiki. Contiki is always using 16b addresses in places where long and short address should both be legal. > > For whom who are interested i join the PCAP files for initial RS/RA > exchanges, and an example of Ping send with Local then global with a Contiki > IPV6 device. > > Pierre-emmanuel > > > -- Jon Smirl jonsm...@gmail.com ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Linux-zigbee-devel mailing list Linux-zigbee-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
