[B.A.T.M.A.N.] Version help

[Corey Combs]

Hello,

I'm currently working on a project that uses BATMAN for a mesh network
across multiple Beagle Bone Blacks which are running a Debian version
7.9 at the moment.  They also are running batctl debian-2012.1.0-1
[batman-adv 2012.5.0].  I would like to connect a laptop to the
existing network either using Debian or Ubuntu, however I have run
into issues with compatibility.  I configured everything identically
with the laptop and I believe I'm connected to the network, but I
cannot see any other devices on the network.  Is it advisable to
upgrade the version of batctl on the 'bone or downgrade the version on
debian or Ubuntu so that the versions align?  Or is there something
else I am missing in my efforts?

My process for configuring the BBB and the laptop follow this
construct, using appropriate hardware names when required.  I have it
all in a script that runs on startup so it differs a little from the
lines below.  Each node has it's own assigned IP address as well.

modprobe batman-adv
batctl if add eth0
ifup wlan0
ifconfig wlan0
ifconfig wlan0 down
ifconfig wlan0 mtu 1532
iwconfig wlan0 mode ad-hoc essid reynoldsplus ap CA:FE:C0:DE:F0:0D channel 11
batctl if add wlan0
ifconfig wlan0 up
ifconfig bat0 up
ifconfig bat0 10.200.8.1
route add default gw 10.0.99.1
echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
echo 1 > /proc/sys/net/ipv4/ip_forward

Thank you.

Corey

Hi Corey,

there are some differences between batman-adv <2013.4 and after that. Please 
see here:

https://www.open-mesh.org/projects/batman-adv/wiki/Compatversion

In general, we would advise to update both Kernelmodule and batctl to 
something newer. 2012 is ... ancient.

Cheers,
     Simon

Uhm, 2012.5.0 is extreme old and I would advise not to use such an old 
version. And beside that, it is using COMPAT_VERSION 14 [1]. The current 
COMPAT_VERSION is 15 - batman-adv kernel modules with different 
COMPAT_VERSIONs cannot talk to each other.

Why batctl? The biggest problem here is the extreme old batman-adv version 
which is not compatible with every batman-adv version since 2014.

And btw. you didn't tell us what batman-adv version your laptop is using. If 
they are really using the same version then it could be that either the laptop 
or the beagle bone blacks have problems with their wifi driver. Wouldn't be
the first time that things like broadcast or unicast communication via IBSS 
is broken with some wifi hw/driver.

Kind regards,
	Sven
