Hi Alexander, Yes, I did read the documentation, this is how I came up with the series of command I pasted in my original mail. The documentation says: "1. Add IEEE802.15.4 interface and initialize PANid;", which I translated by: > izattach /dev/ttyUSB1 > iz add wpan-phy0 > ip link set wpan0 address ca:fe:ca:fe:ca:fe:ca:fe > ifconfig wpan0 up > izcoordinator -i wpan0 -s 1 -p 777 -c 11 -l lease &
I guess it should be compatible with the use of 6LoWPAN. And then, step 2 to 4 are just copy and paste from the documentation. Could you confirm that this should work? As for the status of the Linux-zigbee kernel, there is only one change in the 6lowpan.* files: lowpan_set_address has been replaced by eth_mac_addr. I overwrote the 6lowpan.* files with the corresponding files of the mainline kernel (Linus branch), but it didn't do me any good and my laptops are still crashing when I "up" the interface. Perhaps, were you implying that some important ieee802154 files have changed as well? I'll give a try to a mainline kernel, and I'll let you know. In case you are interested, I attached after my signature the two call trace I mostly obtain when the kernel crash (perhaps depending on the other application that are running at the moment of the crash).
