Hi folks, I'm new to the this project and excited at the possibilities of
Linux/Zigbee. I've been playing with a radio driver for a while, and more
so now that there is a SoftMAC available to support radios like the
AT86RF23x series.
I've ported the SoftMAC to linux-2.6.39 running on an ARM and am
experimenting with an AT86RF231 radio driver. The radio is working but
when I follow the instructions in Getting Started and get to "ifconfig
wpan0 up" I get the following:
# ifconfig wpan0 up

Is strange because even though "ifconfig" doesn't show wpan0 as being up
but when I send a packet, my driver receives it and looks as if its
processing the data (debug output below).
mac802154_subif_rx()
parse_frame_start: 0803 dsn35
parse_frame_start(): src addr_type is NONE
parse_frame_start(): dst PAN address ffff
parse_frame_start(): dst SHORT address ffff
mac802154_wpans_rx() frame 3
mac802154_subif_frame Getting packet via slave interface wpan0
Command 07 on device wpan0
Anyone have any suggestions on where to go from here? I'm just getting my
hands dirty in the SoftMAC portion unfortunately - I was hoping it would
just work! :)
Thanks, Matt.
