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
