Thank you for reporting this issue and sending us the dumps.
Actually it is very hard to link the ap isolation mechanism to this problem.

First of all I would like to make a simple test. Please, could you use dump
packets received on T003 and see if the ARP request (the first one that receives no reply)
reaches the node (T003)?

In particular I would
suggest you to use wireshark (it can parse batman packets) and to sniff at the
same time packets either from the physical interface used by the mesh (I'd say wlan0)
and bat0.

Then tell us if you see the ARP request on both interfaces, on wlan0 only or on none
of them.

Another question, why are you using the bridge loop avoidance? If possible I
would like you to disable any optional feature you have in order to have the
cleanest testbed possible. I know that you already tried to disable it without
effect, but it is better to perform test without any other "noise".

Cheers,
