hi,
this mail would be my first post to the list so for a starter i would like
to thank to the project owners, contributors and the community for the great
work being done and appreciate the effort and time being spent for this piece of
software like it is said software is hard.
the main reason i am writing is as follows;
for about 10 months i have been experimenting with batman on various platforms
my current platform is ti's beagleboneblack wireless board running openwrt
distribution (the required bbbw dtb and wl1835 driver firmware applied) with
batman enabled and configured. with this high level description of the
components i am able to build a mesh network 6 nodes (i.e. bbbw cards) but as
soon as i introduce a 7th card into the network batman mesh becomes unresponsive
as the last seen times start to increase and finally, after 200 seconds all the
nodes drops from the originator and neighbor tables which could be inspected
with < :#batctl o> and < :#batctl n> commands respectively. all the cards are on
the same table and well powered.
i would like to give some details about the
configurations of the cards which are identical except the ip addresses

at this point everything is fine i can level 2 ping each neighbor etc. but when
i boot up the 6th neighbor (i.e. 7th node in the mesh network) last-seen values
start to increase and finally nodes disappear
