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].
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.
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?
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
