Hi,

please DON'T use the sourceforge mailinglist. We have linux-wpan now

However, doing real stuff on the MAC seems still broken as already mentioned here (Re: [Linux-zigbee-devel] 802.15.4 scan, scan_req and ieee802154_nl_scan_confirm()<http://www.spinics.net/lists/linux-wpan/msg00365.html>). That is, a scan - which would be the first step in network establishment - still fails

yes you are right any mlme ops was never "right" implemented. What you
see there is only some callbacks structures to make them available for
HardMAC drivers. (Then you need only to implement the interface and not
the real algorithm). That's my assumptation what the previous
maintainers did there.

Yes the rework is still in progress and the MLME ops state isn't changed
yet. The rework will do some things more "generic" so we have the chance
to implement MLME ops.

The rework also contains various changes to grab some good things from
wireless stack but with 802.15.4 functionality.

You need the wpan-tools which is based on iw now. See [0].

I would hope this to be possible with the lowpan-tools but welcome any new tools there as well.

See [0], but we also have no coordinator support. The further plans are
to add a "coordinator" interface type.
