Hi,
At first everything seemed to work. A node on the one end could ping a node on the other end over the mesh-network. The ping was hopping from node to node as expected.
But sometimes some paths do not work anymore.
Some nodes can only reach their direct neighbors via a "normal ping". A ping to a node via one hop does not work. A "batctl ping" does work!
This only happens to parts of the network and is not permanent. If i wait it will recover, but then the problem appears at another node.
since "batctl ping" works I'd say your mesh works fine - you have a problem in your higher layers. Maybe a mac address collision or an ARP timeout ?
Can you provide specific examples we can go through ? For instance, provide the batctl ping output to the neighbor in question, the ping error message (does it say timeout / host could not be found / etc), a batctl traceroute to the neighbor in question and the output of the global translation table.
Are you trying to ping a 'fixed' node or a node that is roaming ?
