Hello Sven,
Thank your for your swift reply and advice. As you said TI supports limited number of peers with its driver and hardware in mesh mode. According to TI documentation it is 32 nodes. The question bogging my mind is how could the < :#iw dev adhoc0 station dump > command return 6 active and plink established nodes (with inactive times around 80ms) while batman-adv's last-seen is increasing till timeout occurs on all neighbors and after timeout iw station dump still reports the same active stations (with inactive times around 80ms). Am I missing something to debug or a log to look in to or a configuration tied with batman-adv needed to be made.
Thank you and best regards

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 researched for a while for the cause with no avail. i would appreciate any kind of help to point me to the right direction to solve this.
Please don't use things like wl1835 when building larger meshes. It is known that these kind of devices only support a very limited amount of peers and are most of the time only (more or less) stable in management mode (client). And afaik, the wlcore driver (like other TI wirelss drivers) is also orphaned.
If you're wifi link/driver doesn't work, batman-adv can also do nothing to fix it.
Rule of thumb: If it is a USB/SDIO wifi device, start waving your hands in the air, scream and run away. This strategy is also helpful in other wifi related situations.
Kind regards, Sven
