Hi Michael,

You have a bridge loop here, you cannot put an interface into
batman-adv and bridge the same one with bat0 again which seems to
be the case for wlan0. Packets will enter wlan0, batman will grab
them, encapsulate it in its own batman header and send the same
packet on wlan0 again, reaching another batman-adv
node, which encapsulates the same packet again etc.

Please check
http://www.open-mesh.org/wiki/batman-adv-quick-start-guide and try
starting with a simpler setup first.

Also have a look at
http://www.open-mesh.org/wiki/batman-adv-troubleshooting, if
there's anything missing in this one, we'll be happy to add it.

Cheers, Linus
